Flowstop - Inflatable Pipeline Stoppers

FLOWSTOP products fall into two broad categories:

Pipeline stoppers which, when deflated, are slightly smaller than the diameter of the pipe to be sealed. These require access to the main diameter of the pipe.

Stoppers which when delated can be compressed to fit through an opening of ¼ the pipe diameter or less.
Some have a spinal tube so that they can be pushed into position against the flow in the pipe. Others are unsupported and when inserted go with the flow in the pipe.

The major criteria which need to be considered when choosing the right stopper for your application are the following:

The internal diameter of the pipe to be temporarily sealed

The condition of the pipe

Whether the pipe is circular or possibly distorted

The fluid in the pipe (gas, oil, chemical, milk, effluent)

The hold back pressure required

FLOWSTOP pipeline stoppers are in use throughout the world. The more common applications are gas pipeline stop-offs, drain testing, pipe testing, pipeline maintenance, chemical factory pipe work maintenance, milk processing plant maintenance, food processing plant maintenance, and as cores to form special shapes of concrete pipe.
