LineStop Heads

The LineStop heads or Pivots are used, after hottap operation, as a mechanical stoppers. They are introduced by an actuator to stop the flow in the line.  They should be manufactured very close to the ID of pipeline.

We manufacture them for ID from 2″ to 56″ and for different maximum pressure of operation.
