How do you perform a burst test?

December 1, 2010

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 are the quality tests that are conducted on expansion joints?

At U.S. Bellows, we perform a variety of tests:

  • Burst Testing – The objective of the burst test is to determine the ultimate pressure resistance. Primarily conducted on bellows. Normally, hydraulic pressure is slowly increased until failure occurs.
  • Dye Penetration Testing – Liquid dye is used to locate leaks or cracks in the bellows.
  • Hydro Testing – Bellows are pressurized for 30 minutes to locate leaks or cracks.
