48" Hottap for a 72" Linestop with a 48" By Pass Video

The City of Kansas City presented IFT with the opportunity to provide our services in order to allow the replacement of 72” valves on a Pre-Stressed Concrete Cylinder Pipe (PCCP) sewage force-main. Their 72” force-main being under pressure was a critical component of the Kansas City sewage collection system and the line could not be shut down.

Continuation of the raw sewage flow was performed by direct pumping from the wet-well into two 48” temporary pipelines that were hot tapped upstream of the 72” Linestop®. The 72” Linestop® plugged sewage from heading toward the wet well infrastructure thus allowing various large diameter valves to be replaced without a shutdown.

This raw sewage was successfully bypassed with use of the IFT Linestop® so the 72” pipeline remained active while the system was upgraded. IFT provides Large Linestop® services on most types of pipelines through 78”. IFT now headed to Houston to perform another 72” Linestop.
