New HK1 Hydraulic Wonder Wrench
Seriously. Hydraulic. Replaces twenty-three separate size wrenches with this one compact tool. The narrow profile allows it to fit into the tightest of workspaces and a ten degree tapered head leaves plenty of knuckle clearance too. Each end of the wrench features a hexagonal head with an adjustable piston slider to provide a three sided, full surface contact fitting with the bolt. Even works to extricate damaged, stripped and rounded-off bolts. It's hydrokinetic slider system is faster and easier to adjust to the proper size. Turn the valve located in the center of the wrench a quarter turn to release piston, adjust to bolt or nut diameter, and tighten for a firm, custom grip on every fastener. Cold forged steel construction and nickel plating combined with superior versatility make this tool destined to become a favorite. 7.25" x .5", 10 oz.

Hydraulic Leak Delays Test Ahead Of 'Static Kill'
This is MORNING EDITION, from NPR News. Good morning. I'm Renee Montagne.
STEVE INSKEEP, host:
And I'm Steve Inskeep.
This could be the day that BP plugs its damaged well in the Gulf of Mexico. The oil company says it plans to pump heavy fluid down into the well, and in the lingo of the gas and oil industry: kill it. Also today, BP has a better idea of the scope of the disaster and the fines it will have to pay.
We're going to catch with all of this with NPR's science correspondent Richard Harris, who's been covering this story from the beginning. He's in our studios.
Richard, good morning.
RICHARD HARRIS: Good morning, Steve.
INSKEEP: Okay, the plan to kill the well, as it's put - how's that going to work?
HARRIS: Well, you start with a huge pile of heavy fluid called drilling mud, and it's up on a ship. You take pumps - they're giant pumps on a ship, also. You pump it down 5,000 feet through the water column, and it plugs right into -these pipes plug right in to the blowout preventer, which is down on the seafloor. You very gently turn up the volume of this pressure, and the mud gets - very slowly starts to push in. And...
INSKEEP: Basically, it's like clogging a drain, pretty much.
HARRIS: Like clogging a drain. They call this bullheading, which is a great term, because you can just think of bull's head pushing against something. And they basically want to push the oil that's in the well right now down gently, but firmly and continuously, till it get all the way to the reservoir - 35,000 feet below the seafloor. And if they can do that with the mud, then think about it, you have 13,000 feet of mud stacked up there.
It's heavy enough that, basically, it neutralizes the pressure that's been up in the well all the time. And so the well stops flowing. And that's it. It's killed.
INSKEEP: How is that different from the effort to kill the well with drilling mud that was used back earlier in the summer, with no successful result?
HARRIS: Yeah, the so-called top kill...
INSKEEP: Yeah.
HARRIS: ...which was an utter failure. It is the same principle, pretty much. You want to put heavy stuff in the well and push the oil back down. The difference is now they have this cap on top of the well, so with the top kill, essentially, the mud they put in was just immediately spewed out of the well by the oil that was in there, and it just ended up on the seafloor.
INSKEEP: Like a volcano.
HARRIS: Yeah, exactly. And so basically, that didn't work because there was nothing to hold it in. Now they have this cap, they can hold the mud in place. And so this seems to be something that has a very high degree of likelihood of success.
INSKEEP: Are there still some risks here, though?
HARRIS: There are always risks, although they seem to be pretty calm about this one, because they only have to turn the pressure by just a little bit in order to move the mud down. And so they're not terribly concerned about doing damage to the well.
INSKEEP: And then having gotten the mud in there, you put cement on top of the mud?
HARRIS: Yup, there are a couple of plans for putting in the cement, 'cause that's what you ultimately want to do to make sure it's sealed permanently. The mud will sit there, but you obviously want cement caps. And one way you can do it is you can do the same thing. You can put a slug of cement on the top of the well and gradually push it down. And again, you would want to push it all the way down into the bottom of the well, if you could do that.
Or, remember, we have that relief well that's within like a hundred feet of intercepting at the very bottom of the well. And the original plan, actually, was to pour cement down, pump cement down the relief well and plug using the relief well. They might actually do a combination of both, or one or the other. That remains to be seen.
INSKEEP: We're talking with NPR's Richard Harris on this day when BP might be able to plug this well, permanently, in the Gulf of Mexico.
And, Richard, I'm glad you're here, because a few months ago, you assembled some scientists, independent scientists, to try to estimate how much oil was actually coming out of this well. And now we have from the government a little better idea of how much oil really did come out. How close were you?
HARRIS: Actually those scientists turned out to be remarkably accurate. They estimated about 70,000 barrels of oil and gas a day coming out of the well. The new federal estimate is that something like 62,000 barrels of oil were coming out of the well at the time. They were really almost right on the money. It's quite remarkable. And this was just looking at really raw video that was not high quality. They just had some pretty sophisticated ways of looking at that and figuring out how much oil was flowing.
So let's put these numbers in a little bit of perspective. Now, if you add up over the 86 days, the amount of oil has gradually decreased coming out of the well. But the federal government now estimates that over the entire time, about five million barrels of oil came out the well. BP captured about one million of it - well, not quite. But that left about four million that went into the Gulf. And that's a pretty big number from the standpoint of the ecosystem, but it only represents about five hours of oil consumption in the U.S.
INSKEEP: Wow. Two quick questions, though. How much do have to pay when you spill that many millions of barrels of oil in the ocean?
HARRIS: Well, it's - the fines started at $1,000 per barrel, up to $4,300 per barrel, depending upon negligence, and so on, like that.
INSKEEP: Billions of dollars.
HARRIS: Billions of - so it could be $18 billion, something along those lines.
INSKEEP: Eighteen billion dollars. Well, that raises another question having to do with money, Richard Harris, and also having to do with oil. There are still millions of barrels underneath the Gulf in this well that's being plugged as soon as today, right?
HARRIS: That's correct. And there's been a lot of speculation about whether BP would go back in and try to get it. They do have - they've drilled these two relief wells that are tantalizingly close to this reservoir. But yesterday, somebody at BP, a vice president was asked: Are you going to go after that oil with those relief wells? He said, absolutely not. We're going to seal it up, and we're going to leave them alone.
INSKEEP: Not worth the PR costs or...
HARRIS: Apparently not.
INSKEEP: ...or the risk. Or the risk.
Richard, thanks very much.
HARRIS: My pleasure.
INSKEEP: That's NPR's science correspondent Richard Harris this morning.

Hydraulic drive trencher
The improvements made as a result of the experience of the 300P series 1 to 3 have made it possible for the UNAC research department to design and produce the UNAC series 4 300P, equipped with a new generation 300hp Caterpillar diesel engine. The UNAC 300P carrier is versatile. Changing from one tool to another - saw, chain orvibrating ploughshare - can be done in an average time of one hour. This makes it possible for the same carrier to be available for all types of worksite. Thanks to the tilt corrector and hydraulic offset, the tool remains permanently vertical.
The 300P also exists in a 500hp version. On the same basis as the 300P carrier, UNAC has developed the 300C carrier, on caterpillar tracks. It has been studied for work in all conditions, and is equipped with a chain and vibrating ploughshare.

Hydraulic fracking spells disaster
Despite industry claims that the rapidly expanding practice of hydraulic fracturing to extract natural gas from deep underground shale layers is “perfectly safe,” on April 15 the Pennsylvania Department of Environmental Protection fined Houston-based Cabot Oil and Gas $240,000 for causing the contamination of 14 residential water wells in Dimock Township, Pa.
The company was also ordered to plug three gas wells it was operating in the town, which sits atop the Marcellus Shale formation, and was banned from drilling in the area. One water well in Dimock exploded last year, and DEP inspectors witnessed gas bubbling up at the base of eight other wells in March. Despite the ruling, Cabot has plans to drill 100 new wells in Dimock this year.
Independent newsroom ProPublica has reported on 50 similar cases across Pennsylvania, including reports of fish kills, water and air pollution, fires, out-of-control flaring, human illnesses and animal deaths.
The concern over the safety of hydraulic fracturing has prompted calls for a moratorium on drilling in Pennsylvania. In the process, often referred to as fracking, 2 to 9 millions of gallons of water, mixed with sand and up to 250 chemicals, are pushed into underground shale layers to release natural gas.
In January the Pennsylvania state Legislature opened up 32,000 additional acres of state forest land to be leased for drilling. As a result, 692,000 acres of the 2.1 million acres of state forest land are now open for gas wells. During a recent push to expand the practice into the Delaware River basin, the Philadelphia City Council was pressured to pass a resolution on March 25 calling for an environmental impact statement before any new permits are issued.
Fracking has been in use for a number of years throughout the U.S., particularly in the Southwest. Five natural gas sites border the town of Dish, Texas, in a quarter-mile complex. In nearby Fort Worth, Texas, 1,400 wells have been drilled in urban areas, many near schools and residential centers.
Speaking at a meeting at Temple University’s Department of Civil and Environmental Engineering on April 16, Dish Mayor Calvin Tillman described how carcinogenic air pollution from natural gas drilling has damaged the quality of life in his town of 180 residents. The town sits atop the Barnett Shale, a geological formation similar to the Marcellus Shale.
Using his own money, Tillman has been traveling to Pennsylvania and New York to warn about the dangers of the gas boom. In his small town, trees are dying on a 30-acre farm that adjoins a labyrinth of small underground pipelines used to transport fuel from the fracking wells to outside markets. Horses have also fallen ill. Residents report problems with frequent nausea, severe headaches, breathing difficulties, chronic eye irritation, allergies, throat irritations and even brain disorders.
When Texas state inspectors, who are usually linked to the drilling companies, reported they could not find any problem with the wells, Dish town officials hired an environmental firm to collect one-day air samples near the compressors. Their study found high levels of 15 chemicals, including benzene, a known carcinogen. As a result the Texas Commission on Environmental Quality conducted air studies at 94 sites in the region. They found two sites with very high levels of benzene and 19 others with levels that raised concern.
In April, blood and urine testing of 28 adult Dish residents revealed that half the residents had slightly elevated levels of benzene and other contaminants. Four residents tested positive for benzene, including Tillman. Tillman noted that no testing was done on children, pregnant women or the elderly — groups likely to be most susceptible to the contaminants. Tillman’s water also tested positive for traces of styrene, ethyl benzene and xylene.
Growing concern over the danger of fracking has led to a push for legislation in Pennsylvania that would require drillers to disclose chemical ingredients in hydraulic fracturing fluids. Other proposed legislation calls for a moratorium on drilling until environmental impact studies can be performed. Both bills have yet to be passed and face mounting opposition from the natural gas industry.
Nationally, the oil and gas industry won exemption from major provisions of the Safe Drinking Water Act, the Clean Water Act and other federal environmental laws with the passage of the 2005 Energy Bill. The bill’s “Halliburton loophole” protected the company from having to reveal the composition of their fracturing fluid, despite the fact that the list of hazardous substances compiled by the Environmental Protection Agency’s Superfund — the program established to address abandoned hazardous waste sites — includes toxic profiles on benzene, styrene, toluene and other agents known to be in the mix. Efforts are also underway to challenge this legislation.
The EPA announced it will spend $4.4 million to start a study on the impact of fracturing in October, but Dr. Michel Boufadel, director of the Environmental Hydrology and Hydraulics Laboratory at Temple University College of Engineering, expressed concerns that the EPA’s study does not go far enough.
Speaking at the April 16 meeting, Boufadel noted that very few scientific studies on fracking have been conducted by researchers not connected to the drilling industry. He also pointed out that most studies assume that any leak of water contaminated by fracturing fluids would spread horizontally from a holding tank and be detected by ground level monitors.
Boufadel explained that the 250 chemicals contained in the fracturing fluid create “gooey, high density water” — a gel that suspends the sand particles needed to work into cracks in the shale layers. The result is “radioactive water six times more saline than sea water and containing known carcinogens.”
“If you don’t account for this heavy density you would expect water to move outward, but the reality is that it moves down,” Boufadel stressed. “If you only use existing traditional models of monitoring wells at ground level, you won’t detect contamination until it’s too late.”

The company was also ordered to plug three gas wells it was operating in the town, which sits atop the Marcellus Shale formation, and was banned from drilling in the area. One water well in Dimock exploded last year, and DEP inspectors witnessed gas bubbling up at the base of eight other wells in March. Despite the ruling, Cabot has plans to drill 100 new wells in Dimock this year.
Independent newsroom ProPublica has reported on 50 similar cases across Pennsylvania, including reports of fish kills, water and air pollution, fires, out-of-control flaring, human illnesses and animal deaths.
The concern over the safety of hydraulic fracturing has prompted calls for a moratorium on drilling in Pennsylvania. In the process, often referred to as fracking, 2 to 9 millions of gallons of water, mixed with sand and up to 250 chemicals, are pushed into underground shale layers to release natural gas.
In January the Pennsylvania state Legislature opened up 32,000 additional acres of state forest land to be leased for drilling. As a result, 692,000 acres of the 2.1 million acres of state forest land are now open for gas wells. During a recent push to expand the practice into the Delaware River basin, the Philadelphia City Council was pressured to pass a resolution on March 25 calling for an environmental impact statement before any new permits are issued.
Fracking has been in use for a number of years throughout the U.S., particularly in the Southwest. Five natural gas sites border the town of Dish, Texas, in a quarter-mile complex. In nearby Fort Worth, Texas, 1,400 wells have been drilled in urban areas, many near schools and residential centers.
Speaking at a meeting at Temple University’s Department of Civil and Environmental Engineering on April 16, Dish Mayor Calvin Tillman described how carcinogenic air pollution from natural gas drilling has damaged the quality of life in his town of 180 residents. The town sits atop the Barnett Shale, a geological formation similar to the Marcellus Shale.
Using his own money, Tillman has been traveling to Pennsylvania and New York to warn about the dangers of the gas boom. In his small town, trees are dying on a 30-acre farm that adjoins a labyrinth of small underground pipelines used to transport fuel from the fracking wells to outside markets. Horses have also fallen ill. Residents report problems with frequent nausea, severe headaches, breathing difficulties, chronic eye irritation, allergies, throat irritations and even brain disorders.
When Texas state inspectors, who are usually linked to the drilling companies, reported they could not find any problem with the wells, Dish town officials hired an environmental firm to collect one-day air samples near the compressors. Their study found high levels of 15 chemicals, including benzene, a known carcinogen. As a result the Texas Commission on Environmental Quality conducted air studies at 94 sites in the region. They found two sites with very high levels of benzene and 19 others with levels that raised concern.
In April, blood and urine testing of 28 adult Dish residents revealed that half the residents had slightly elevated levels of benzene and other contaminants. Four residents tested positive for benzene, including Tillman.

D*1FP servo valves enhance large hydraulic systems
Parker Hannifin has brought out the D*1FP range of pilot-operated servo proportional valves.
These are based on the company's direct-operated DFplus hydraulics control valve, which features Parker's Voice Coil Drive (VCD) technology.
The control behaviour of the Parker Hannifin D*1FP series valves ensures high stability in operation and easy, time-saving installation and set-up.Parker is using it to control the high forces within hydraulic valves.
By producing dynamics on a par with modern servo valves, the VCD technology results in a much simpler valve structure.
The new pilot-operated D*1FP series has transferred the advantages of the VCD to larger frame sizes and higher flow-rate valves.
The high dynamics and precision of each new pilot valve deliver optimum control of the main spool, resulting in servo-class performance from the complete valve.
The control behaviour of the valves ensures high stability in operation and easy, time-saving installation and set-up.
Whether in the direct or pilot-operated valves, the VCD technology offers the same benefits of robust design and long life.
A new safety concept with the pilot valve can also reduce the need for additional shut-off valves in hydraulics systems.
It ensures the main stage is hydraulically balanced at power down and the main spool is in a safe position.
The D*1FP range is available in four sizes: NG10 (CETOP05), NG16 (CETOP07), NG25 (CETOP08) and NG32 (CETOP10).
With flow rates of up to 3000 litres a minute, the valves bring the advantages of VCD technology to almost any size of hydraulics system and are supported around the world by Parker's global network of manufacturing, sales and customer-support centres.

Australian Brake Controls’ air/hydraulic brakes keep tractors and trailers controlled
A CONTRACTOR from Mel-Ray Industries has installed a dual-line air/hydraulic braking system from Australian Brake Controls in his tractors and trailers.
According to Ray Galdes, towing a heavy trailer around worksites can be a potentially hazardous, high maintenance undertaking.
Trucks, tractors and specialized machinery can be subjected to loads that will place unusual stresses on standard components, including high demands on braking systems in situations where operators need to selectively and powerfully apply stopping and holding power.
Examples include going down a one-in-four slope with a 90-degree turn at the bottom. Gravity will see the trailer trying to push straight ahead, off the road. Galdes says he helped increase the responsiveness and control over the vehicles with the Australian Brake Controls system.
His latest system enables the driver to simultaneously control both the tractor’s hydraulic brakes and trailer’s air brakes from the same brake pedal. The operator can also operate the trailer brakes separately using an in-cab hand control.
Galdes says air brakes are the most effective, as other types of brakes get burned out quickly on slopes.
Australian Brake Controls engineered a system which incorporates a tractor-mounted half horsepower electric compressor feeding a nine litre pneumatic holding tank linked by airlines to the trailer brakes.
This pneumatic system is synchronized with the tractor’s hydraulic system via a reaction valve that automatically senses the amount of pressure being applied to the hydraulic system and turns this into an air signal for the trailer’s air system when the brakes are applied.

Hydraulic fracing dominates ExxonMobil-XTO merger hearing
A congressional hearing that ostensibly was supposed to consider a proposed merger’s market impacts quickly became a forum for debating whether to federally regulate hydraulic fracturing.
Chairman Edward J. Markey (D-Mass.) convened the Jan. 20 hearing of the House Energy and Commerce Committee’s Energy and Environment Subcommittee to examine energy market impacts of ExxonMobil Corp.’s proposed $41 billion purchase of XTO Energy Corp. “This merger heralds a fundamental long-term shift in US energy markets, and one that deserves our close attention,” he said in his opening statement.
But the discussion quickly turned to hydraulic fracing because the proposed combination’s agreement includes a termination provision if Congress enacts legislation making hydraulic fracing too costly and uneconomic.
“This country has a propensity to regulate. We need to protect our shareholders,” ExxonMobil Chief Executive Officer Rex W. Tillerson told the subcommittee.
ExxonMobil wants to acquire the Fort Worth, Tex., independent because XTO’s US unconventional gas resource base and technical expertise would go well with the major’s global reach, research and development capabilities, and financial capacity, Tillerson said.
“The development of our combined resources will create the opportunity for more jobs and investment in the production of natural gas across many parts of the United States,” Tillerson said. “It will support our nation’s economic recovery, strengthen [its] energy security, and help meet [its] environmental goals.”
Focus on gas
Bob R. Simpson, XTO chairman and founder, said the company’s management decided soon after it started to focus not only on gas, but also on long-lived, high-producing reserves. That led it to tight shale gas, where it eventually became an industry leader, he indicated.
“In reviewing our future path, we realized that we needed to look at options to take what we have achieved and bring it to a new level,” he testified. “We recognized that the opportunities before us could best reach their potential if we could find an organization that could bring additional scale, technology, and financial capacity to the work we have been doing. We found that organization in ExxonMobil.”
Markey suggested that the proposed merger has positive aspects, including the signal that another multinational oil company is willing to invest in developing unconventional US gas resources. But he also said that Congress wants to make certain those resources are developed safely, which is why it asked the US Environmental Protection Agency to study hydraulic fracing’s operating record.
Republicans on the subcommittee said the technology is safe. “It is well known that gas will play a more prominent role in a carbon-restrained world,” said ranking minority member Fred Upton (R-Mich.). “In fact, the success of any climate-change policy will need to rely heavily on gas. Yet some members of Congress are seeking policies that would take a majority of our domestic gas off the table.”
Several Democrats said the process uses toxic substances that would create serious problems if they entered drinking water supplies. Rep. Diana DeGette (D-Colo.), who is not a member of this subcommittee, was allowed to participate because she introduced a bill last year to federally regulate hydraulic fracing under the Safe Drinking Water Act.
“I support hydraulic fracturing,” she said. “My bill would not make it illegal or impractical. It simply would require disclosure of ingredients in an emergency situation while protecting proprietary information.”
Fluid confined
Tillerson and Simpson both said they would not have a problem as producers disclosing ingredients in hydraulic fracing fluid, which is primarily water. They also pointed out that the process occurs several hundred feet below drinking water supplies, and that concrete casing keeps hydrofrac fluid confined while it’s pumped below the surface.
States already regulate hydraulic fracing aggressively, they continued. DeGette immediately challenged that idea, noting that only four states have regulations that specifically deal with the process. The executives responded that several others have water-management regulations that serve similar purposes.
They also contended that federally regulating hydraulic fracing simply would add another layer to a process that states already regulate well. Restricting its use would harm conventional production too, Tillerson added. “A lot of conventional wells use hydraulic fracturing to make production commercial,” he said.
When DeGette asked them how much they think having to comply with SDWA regulations in using hydraulic fracing would cost their companies, the ExxonMobil and XTO executives said they did not know. “Much of it would depend on how EPA decided to implement its regulation,” Tillerson told her. “I don’t know what would be in it, and neither do you.”
Markey concluded the hearing by stating, “There is no secret plot on this side of the aisle to ban hydraulic fracturing.” But when he was asked by reporters afterward if he planned to schedule DeGette’s bill for markup, the subcommittee chairman replied, “I’m going to have to have further discussions with her on it before I decide.”
