Hydrostatic Pressure Testing

Hydrostatic pressure testing, also known as hydrostatic testing or leak testing, provides a method for finding leaks or verifying performance and durability in pressure vessels. The hydrostatic pressure test is classified as one of LTI’s nondestructive testing techniques, meaning the sample is typically not harmed during the test.

Hydrostatic Pressure Testing at LTI

The procedure used for hydrostatic pressure testing entails the following steps:

Filling the test piece with water or oil
Removing air from the test piece
Pressurizing the vessel to the appropriate PSI
Examining the test piece for any leaks or changes to shape

A decrease in the applied pressure, leakage through the product, or deformation, distortion, or bulging in the product indicates inadequate vessel quality. Hydrostatic testing can also be performed by filling the piece with air while submerged under water.

LTI is equipped to perform hydrostatic pressure testing using water, oil, or air, depending on the specification and customer requirements. The most common method of hydrostatic testing is with water as the test medium because it is less expensive than oil and easier to set up than pneumatic (air underwater).

The hydrostatic test is often ordered with our ultrasonic testing (UT) service. Our state-of-the-art UT/hydro facility has an automated identification marking system for tubing, pipe, and bar.

I wanted to thank you guys for really coming through for us. You guys were relentless responding to our requests. LTI Rocks!

I just wanted to take a moment here to thank you and LTI team for making it a great year for us. I have been recently getting great feedback on the data that I compiled for our project. And needless to say – the only reason I was able to accomplish this was for your timely testing of all the 100s of coupons I had this year. It all so beautifully played out. Really appreciate your on-time turn-around of data, even though I sometimes make it hard for y’all, haha! And also your very prompt responses to my every question. It has been great working with you all this past year and looking forward to the new year. Thank you once again! Heads-up – we have a ton of samples that will be coming your way in the new year!

A warm and friendly customer service, with a phenomenal technical team always willing to support.
