Many industries, whether they are industries centered around manufacturing, research, or property development, often need to rely on pipes, cylinders, or other such related products in order to operate at full capacity. In order to ensure absolute quality with the types of pipes or cylinders used in these industries, it is important to test and provide consistent results in their performance and integrity. For this purpose, there are methods of pressure testing to help provide the assurance needed for clientele.
Burst Pressure
In simplest terms, burst pressure is the amount of pressure a pipe or tube will be able to handle before it begins to rupture or burst. While the pipe or tube is designed in order to withstand a certain threshold of pressure, it is important to also consider other variables, such as environmental conditions, that may also allow the product to fail. While there are a number of formulas and equations taken into account when going through burst pressure testing, the entire method is important to ensure quality and control over the pipe or tube before industries are able to purchase and use in large quantities.
Proof Pressure
While somewhat similar to burst pressure testing, proof pressure testing is a method of testing that shows the maximum amount of pressure that can be supplied before causing permanent damage to its function. The function of this test simply puts the component under an increasing amount of pressure until the pressure rating is reached and held for a specified amount of time. This is often used to also provide fluid leak measurements and expansion measurements.
Combination Testing
It is safe to assume that both burst and proof pressure testing are not done daily, but the idea of combining pressure testing into other stands is an increasing trend in today’s market. Combining the testing capabilities into things like the Impulse Test Stand or ATP test stand are much more common and are, many times, more cost-effective. However, if combining these tests into a stand, keep in mind that there are other variables at play, such as the maximum possible weight or whether or not there will be projectiles upon bursting.
When considering pressure testing for pipes, cylinders, valves, or tubes, keep in mind that the most important part of the operation is to ensure that the tests are done by reputable companies that are completely transparent in their tests. If you are ever in doubt about the pressure testing involved, be sure to contact a professional who can help you further.
