Hammered Pipe Still Standing: Is It Fit for Service?

Author: Kraig S. Shipley, P.E., Piping & Fired Heaters, Principal, Engineer I

Steam piping systems that are not adequately controlling condensate levels may experience a steam hammer event, which is when a slug of condensate is propelled at high velocity down the piping system. When the large dynamic slug force hits an elbow or pipe cap, it can displace the piping system or slide the pipe shoes off the structural members. In this case study, Kraig Shipley discusses a recent consulting project that used SIMFLEX-IV to determine if a steam header was still fit -for -service after a steam hammer event.
