What is Hydrotest Header Incident Alert about?
During a hydrotest on a pipeline, a pig launcher acting as a hydrotest header ruptured, causing a massive spill of water into the environment. An investigation found that the header material was subjected to pressures exceeding its yield strength since it was made from low yield strength casing pipe. Lessons included determining material strengths before testing, monitoring pressure from a distance, and using high yield pipe for headers reinforced with end caps to prevent future ruptures. Actions were taken
