FOAMBAG™
Details
Low pressure – The Steve Vick International FOAMBAG™ flowstopping system involves the injection of expanding foam into a fabric bag which is placed in the pipe. The bag holds the liquid foam in place whilst it expands, providing a gas tight seal at full expansion. This technique is used on diameters from 12” – 36” low pressure gas mains.
The SVI Contract Service team has been successfully carrying out FOAMBAG™ operations for over 30 years.
Medium pressure – Using the FOAMBAG™ technique, flowstopping operations are carried out on medium pressure gas services and mains from 3/4” up to 8” at pressures of up to 2bar. Problems associated with flowstopping tapering, vertical pipes, bends and non-standard sizes are easily resolved using the Steve Vick International methods.
