Then, look for corrosion and mold in exposed basementpipes. Take note that leak repair is required nearby if there are signs of corrosion, dampness, mold, or rottenwood. Most likely, behind the wall is where the brokenpipeis. 3. Sewage odor If you still cannot find the leak visible, cons...
Inside of pipe surface leak-prevention toolPURPOSE: To provide a pipe inner face water leakage preventing device which can easily mend water leakage from a pipe body in the case of leakage because of eccentricity of more than a specific value in a pipe body.HASHIMOTO TAKAO橋本 孝夫...
A third potential benefit from casings is that a slow pipeline leak can be contained in the casing and detected via the casing vent pipe rather than slowly undermining the roadway or forming underground pockets of accumulated product. An industry controversy arises because the benefits casings provide...
When a pin and box are made up, the flat surfaces of the shoulders mate against each other and seal to form a strong structure that is also leak proof. The shouldered connection protects the thinner walled body of the drill pipe and the threads inside the connection from damage when the ...
Pipe wall thickness calculation is one of the important basic activities for every piping engineer. Process plants deal with the fluids that flow inside the…

A device for sealing the gap or void between the outer circumference of a pipe and a hole in a wall the pipe passes through includes a sheet metal casing flexible enough to be bent around the pipe. The inside wall of the casing includes... R Graf,D Annemaier - US 被引量: 25发表:...

the pipe A be provided with the absorbent layer 8 and with the detector element 2, both extending along the length of the pipe A where leak detection is desired. Next, an impervious tube 10 of rigid or semi-rigid material is formed inside the tube 8, that impervious tube 10 thereafter ...
Thus this method induces a degree of error for leak detection. In this article, time-frequency method is developed to classify the wave speed of direct waves (non-dispersive waves) and the reflective waves (dispersive waves), respectively. It can determine the leak location with more accuracy ...
