During a turnaround at a gas plant, pressure testing was performed on a sulphur condenser’s (the “vessel”) shell side. The vessel was accidentally overpressured to 5.3 times its MAWP (maximum allowable working pressure). A new vessel would have cost over a million dollars and would have taken over 6 months to be built. Acuren performed Level 3 API 579-ASME FFS-1 Fitness for Service, followed by different NDE techniques, hardness testing and strain gauging during a pressure test. We worked very closely with the regulator and the customer to eventually bring the vessel back to service.

Acuren’s Ammonia System Inspection group helped a food industry giant avoid a possible shutdown. Acuren’s experts were tasked with inspecting the pipes and vessels involved in a 75,000 pound ammonia system in Arkansas. The main concern of every ammonia system is corroded pipe that can risk the safety of employees, surroundings, and efficiency of the plant that could ultimately even cause a shutdown. Acuren’s combined testing solution helps clients avoid these risks while meeting all regulatory compliance.

There are two 30 inch diameter ¼” wall thickness steel water mains, which run along the underside of the bridge over a river way, that provide major water distribution to the community. The leak locations were difficult to access and on pipe which had an old asbestos coating. Acuren’s engineering and rope access crew provided a safe, economical, and timely repair solution to get the lines back into operating condition.
