What Goes Into Testing For Leaks
Design, research and development and manufacturing work by most industries remains reliant on the use of cylinders, pipes, valves, and the like. To ensure that all these infrastructural installations are in good working order at all times, leak testing houston tx work, amongst a number of other risk management exercises, still needs to be carried out. This contributes towards ensuring the installations’ integrity and reliability.
A range of testing services are currently being handled to help determine things like proof pressure. Testing measurements will range from as low as just a few PSI to as high as 200,000 PSI. A variety of materials will be used. These could include the use of helium, compressed air, nitrogen and liquid. Test transducers are designed to cover pretty much all pressures. And they need to be calibrated in accordance with the laid down standards of the NIST.
Instrumentation requirements will always vary in accordance with the industrial setting. These will range from the manually recording of data to high speed computer based data capturing utilizing a number of channels. Proof testing and leak testing are closely related. Proof testing is non-destructive. It will determine that a system is able to withstand pressures just above its operating pressure without incurring permanent damage or leaks.
The checking for leaks will require immersions of the part into a clear liquid. This could be water. The part is also pressurized with air, helium or nitrogen. The more complex testing procedure will require the use of a spectrometer. Burst pressure testing, on the other hand, is destructive. It measures pressures at which parts could be permanently damaged. An investigation on how the failure occurs will also be carried out.
Finally, a procedure known as autofrettage helps to improve the fatigue life of high pressure components through pressurization.
