How do you service test an expansion joint?

December 1, 2010

Expansion joints are maintenance free. They can only be tested if the expansion joint is supplied with 2-ply testable bellows using vacuum or air pressure testing.

How do you perform a burst test?

The burst test is primarily conducted on bellows. Normally, hydraulic pressure is slowly increased until failure occurs. Based on the burst test results, a safety factor is applied. This establishes the ultimate pressure rating.

What is burst testing?

The objective of the burst test is to determine the ultimate pressure resistance. This test is primarily conducted on bellows. Normally, hydraulic pressure is slowly increased until failure occurs. Based on the burst test results, a safety factor is applied. This establishes the ultimate pressure rating.
