BJB’s NEW FREEZE JACKETS

BJB’s New Freeze Jackets Provide a Safer Way to Isolate Live Pipelines.

 

For many years, pipe freezing has been a simple method of stopping the flow through sections of pipeline that do not have shutoff valves.   BJB’s new freezing jackets are non-invasive, harmless to the pipe, and easy to apply and use.  Even better, nitrogen is non-toxic, and environmentally friendly.  (Almost 80% of the air we breathe is Nitrogen)

 

Most ordinary freezing jackets vent evaporated nitrogen directly into the air above the pipe.  Normally the Nitrogen will disperse harmlessly into the atmosphere.  However, when these jackets are operated in a trench, the Nitrogen cannot disperse as quickly, and can pose a hazard to operators if it displaces the oxygen in air around the pipe.  BJB’s Freezing jackets conduct the evaporated nitrogen away from the trench so that it can be safely vented.  This can be done with none of the leaking problems that are seen in most freezing jackets.
