The Pipestoppers® division of HFT® has introduced standard and nonstandard inflatable stoppers for tubes, pipes, pipework fabrications, and ductwork. They help simplify routine maintenance or the blocking of pipes for purging.
The stoppers can provide a strong barrier in pipelines to prevent foreign bodies from entering the line during downtime. In machining applications, they can be inserted below a horizontal flange on a vertical pipe to prevent machining fluid from falling into pumps and turbines. Inflated stoppers also can reduce the volume inside large tanks and vessels so that argon purging takes less time and uses less gas.
Standard stoppers are available in cylindrical or spherical formats in sizes from 1 to 96 in.
