Innovative Stopple~r Train Plugging System Achieves Double Block And Bleed

摘要

Whether it's routine maintenance or an emergency repair, work done on a pressurized piping system requires both excellent equipment and proper procedure. The work might take place on a remote section of transmission pipeline far removed from the nearest city, deep below the surface of an ocean, or in the middle of a busy chemical processing plant, but wherever it is, modifications to any active line must be done with the utmost care, and with all appropriate safety measures in place.rnBecause they typically require high concentrations of personnel and large infrastructure investments in a highly volatile environment, hydrocarbon processing facilities such as refineries are increasingly seeking out a double block and bleed option when isolating a section of an active line for repairs or additions without interruption of service.
