A new function was established to better characterize the variation of fracture permeability on pore pressure, and a mathematical model was derived for the buildup test of fractured wells with stress-sensitive conductivity. Several simulation cases involve various conductive fractures were run to plot ...
Hydrostatic testingis performed by filling the piping system with water to the specified test pressure. The test pressure is usually 1.25 to 1.5 times the design pressure. The piping being tested is isolated and filled with water to the test pressure. All joints, both welded and mechanical, are...
The best way to efficiently clean outdoor surfaces is with a pressure washer, a blaster that uses less water to do its work than a garden hose and nozzle.
Explorer Jacques Piccard and U.S. Navy Lt. Don Walsh, are the first people to reach Challenger Deep after a five-hour descent in the Trieste submersible, setting a new record in underwater exploration. They spent approximately 20 minutes on the ocean floor. March 26, 2012 James Cameron make...

Now it has been said in some quarters that trying to impassion a test team can be like coaxing a cat into water and there is a popular misconception that testing can be mundane and boring (I really cannot understand why). So it is imperative that good team dynamics are employed and ...
range of industries and applications. We provide complete systems for a variety of applications, including high-pressure water jetting, hydro blasting, and hydrostatic pressure testing. We also offer high-pressure cleaning, sewer jetting, UHP fire fighting, and high-pressure water sand blasting ...
In particular, one major crack centred on the sides of the blocks, the which may be attributed to bending, was always present after testing. According to Lee, the top and the bottom parts of the specimens were slightly reinforced to minimize shrinkage cracks. In the authors’ opinion, ...
It is important that the outlet lines be unrestricted to ensure minimum back pressure. Orifice B in Fig. 2.15a is placed differently, as is the pilot valve. The port V in Fig. 2.15 offers a new method of control for the compound-type unit. If port V is allowed to be open to the ...
Figure 5. Gerotor pump testing device for (a) oil pump fixtures; (b) monitoring equipment; (c) test console. Figure 6. The test gerotor pump prototype. The gerotor pump is simulated under four different operating conditions, namely, P1 = 0.1, 0.2, 0.3, and 0.4 MPa. The comparison be...
