Hydro test on HDPE

About 10 years ago, I was writing welder qualifiion and hydro testing procedures for HDPE to B31, and was suprised to find that the testing parameters are much more stringent than for steel. I always figured it was becase HDPE, in industrial settings, is often used to carry caustic materials, but that''s just an opinion. Tim

Hydrostatic test - Wikipedia

A hydrostatic test is a way in which pressure vessels such as pipelines, pluing, gas cylinders, boilers and fuel tanks can be tested for strength and leaks. The test involves filling the vessel or pipe system with a liquid, usually water, which may be dyed to aid in visual leak detection, and pressurization of the vessel to the specified test pressure.
