Manufacturers in the nuclear, oil & gas, aerospace and chemical industries need to verify that a given product or component will withstand the conditions in which it is built to operate. Maxbar is the go-to source for quality, customized proof pressure testing services. Regardless of the size or nature of your particular device, we can provide pressure testing to fit your particular need.

What is Proof Testing?

Think of pressure proof testing as a “stamp of approval.” It’s a non-destructive test that verifies that a component, product or system is capable of withstanding a pressure slightly above the intended operating pressure without suffering permanent damage. For instance, if a given pipe or tube is rated at 1,000 PSI internal pressure, we might subject it to 1,500 PSI and observe the effects, checking for any deformation, bending or warping of the material.

Pressure testing is by nature a highly customized service – generally speaking, there are no standard approaches to proof testing. As a result, Maxbar is extremely flexible. We are able to provide the following forms of testing on site:

  • Air testing up to 6,000 PSI
  • Nitrogen or helium testing up to 30,000 PSI
  • Liquid testing up to 200,000 PSI

We have tested components of nearly every conceivable type, ranging from glass chemical vessels (7 PSI) to steel distribution manifolds (170,000 PSI).

In addition, Maxbar provides external pressure testing services. If your component will be subjected to external pressures (such as in subsea applications) and needs to be tested for external compression or bending, Maxbar can design and administer a test to replicate the real-world conditions in which your product will have to perform.

Affordable Proof Testing Services

Because of the specialized nature of pressure testing, many companies don’t have the necessary equipment and manpower. Other companies may have access to proof testing facilities, but are willing to consider alternatives due to the expense involved. This is where Maxbar thrives. We have developed processes and equipment that allow us to provide first-class pressure proof testing services at a price within your budget.

We have the flexibility and experience to provide the customized proof testing services you require. To learn more, contact us.
