Leak Testing of Pressure Vessels
Hydrostatic testing helps evaluate the integrity of vessels that are used under pressure. The hydrostatic test can locate leaks, verify performance or confirm the durability of pressure vessels that undergo testing. The procedure used in performing the hydrostatic test includes filling the test piece with water or oil, then removing air before pressurizing the vessel. Hydrostatic testing of pressure vessels can also be performed by filling the piece with air while it is submerged under water. The test piece is completely examined for any leaks or changes to its shape.
Although leak testing by the hydrostatic test method is considered a nondestructive test, failures can occur when the test piece does not meet performance or durability specifications and may render the piece unusable.
Let Laboratory Testing Inc. evaluate the reliability of pipe, tubing, and coils used under pressure with our leak testing service. Our lab is equipped to perform hydrostatic testing up to 10,000 PSI of pressure. Although the hydrostatic test can be performed by filling the test piece with water, oil or air under water before it is pressurized, LTI most often performs hydrostatic testing with water. This is a very efficient and reliable leak testing process, and is the lowest price of the three methods for our customers.
