Extending and Modifying Operational Pipeline Systems

Aging pipelines that are in place around the world, carrying time critical and costly contents, often need to be shut down for maintenance and repairs. Installing new sections through line stopping can be comprehensive solution to repeated repairs.

Financial Perspective of Shutdown
 
In any system that uses pipelines take big financial hits whenever there is an interruption. Loss of revenue is one, coordinating with manpower is second and finally there is the cost of provisioning alternatives is another. There are many more small ones that add up to big figures at the end of the day when everything is said and done. Hence, interrupting operations is hardly a choice. 

 

Uninterrupted Repairs

 
Line stopping is perfect for pressurized systems. The process allows an operational pipeline to be repaired with interrupting flow. Operation consists of a special flanged fitting, a temporary valve, and our actuator. The fitting is installed and tested, the temporary valve is installed, and the hot tap is completed. After the hot tap, a line stop actuator is installed and stopping head is inserted into the line.

Once repairs have been carried out, the stopping head is removed and a completion plug is set in its place. This seals the flange in place and once a blind flange is set the operations are complete. You may have noticed that not even for once the operations had to be interrupted. Companies which supply important fluids cannot afford downtime of even a few hours which is why line stopping is the ideal procedure for preventive as well as corrective maintenance.
