Applications
Torre® Bagging off system allows for flow stopping operations without gas leaks: repairs, network extensions, branching and any other kind of operation needing flow to be stopped.
Bag inflation
Bags can be inflated with air or nitrogen. Highest inflation pressure is marked on the bag.
Advantages
Advantages over other systems:
- Full safety as no gas leaks occur.
- Flow can be stopped in non squeezable pipes.
- Squeezing release is eliminated and pipes don’t suffer from squeezing.
