Evaluating and Reducing the Risks of Pneumatic Proof-Pressure Testing in Metal Expansion Joints

The pressure testing of Expansion Joints is essential in the industry.

The proof-pressure test shall always be hydrostatic, except where the hydrostatic pressure test is harmful or impractical or the Expansion Joint cannot safely be filled with water. In these instances, a pneumatic pressure test or other alternative tests may be performed.In this article, we focus our attention in evaluating and reducing the risks of Pneumatic Proof-Pressure Testing in Expansion Joints.
