Penetration seals

Hydrocarbon fire rated penetration seals are designed to maintain integrity, fire rating and gas tightness of a penetration through fire and blast rated partition (bulkheads, decks, blast walls, MCT). While geometries of the openings and services going through openings will vary, AIS sealing technology offers a flexible ‘pump in place’ solution to suit multiple configurations.


Our solution
