Tapping Valves and Isolation
Tapping valves are used to isolate main line media while the main line is tapped mechanically. Some tapping valves are designed to be used while the line is under working pressure and in operation, eliminating system downtime. We have done all the dirty work and reduced the never ending lists of tapping valves to our favorite cost effective, durable, time tested, dependable valves you will need for any job.
Tapping Valves Description
Tapping valves are installed using a variety of techniques, including hot tapping, wet tapping, line stopping or plugging, or pipe freezing. Other applications use tapping valves for installing flow meters, probes, or control valves into an existing line. Tapping valves may be installed using a hot tap or a wet tap technique. A hot tap or a wet tap is installed using a pressure-contained tapping machine to attach a tapping valve to the existing pipeline. Hot tapping uses a nozzle or split tee welded to the surface of the existing pressurized pipe. Hot taps are used in refineries, heating and cooling applications, and steam lines. Wet taps use a tapping sleeve that is bolted to the existing pipeline to make a branch connection. Wet tapping is used on sewer or water systems.Need a tapping valve installation?
