Line stop is a method of temporarily isolating and bleeding down part of a pressurized system, for purposes of alteration or maintenance within the isolated section. This is done without shut down of the entire system and without loss of product. If flow must be maintained, a temporary or permanent bypass can be installed around the isolated work section.
Ultrasprings maintains a large inventory of completion style fittings in common sizes and flange ratings for use in low and high-pressure line plugging services / line stop applications. These specialty fittings allow us to work through temporary valves, which Ultrasprings provides, during the plugging operation.
