Expandable Steel V0 Patch
Some applications require remedial operation with maximum sealing efficiency with high gas pressure. Performing a gas tight sealing is a big challenge compared to water tight solution. Our solution was designed to reach the ISO 14310 V0 criteria. The most difficult criteria of this standard.
In addition to our labyrinth sealing system, available on standard patch range, we developed a dynamic sealing system allowing the elastomer seal to auto-energize with differential pressure. The result is a gas tight patch able to seal with internal pressure and external pressure through temperature cycles.
