Specialty Line Stops

Providing innovative line stops solutions for
unique challenges.

Inflatable Line Stops

Inflatable bag stops are another method of line isolation. This method is used when a pipe is out of round or inside surface conditions of the pipe prevent a standard line stop. It can also be used to back up a line stop. A smaller hot tap is made into a pipe and an inflatable bag is inserted into the pipe which stops the flow in the line.

Freeze Stops

The freeze stop is an economical and non-intrusive method used to isolate piping systems. It is ideal for piping made of carbon steel, stainless steel, alloys or cast iron that contain water, hydrocarbons or any chemical with a suitable freeze point and no flow. It is also suitable for effectively isolating sections of pipe where valves are unavailable or inoperable.
