75mm/3” Sarco Flameshield inflatable air bag, with an expansion range from 75-84mm. This air bag can be inflated to a maximum pressure of 15 psi.
Please note: Flameshield air bags are not suitable for pressure retaining purposes, and are designed for use as a barrier to protect the main pipe stopper installed further along the pipe.
Flameshield air bags can be purchased with a 2m or 5m steel braided inflation hose, with firesleeve cover, for a completely fire-retardant set-up. We can manufacture different lengths on request – please contact us if you have specific inflation hose requirements.
Sarco Flameshield inflatable air bags are a heavy-duty stopper, fitted with a spark retardant PROBAN® cotton outer cover and nylon/Kevlar joints. Flameshield bags are designed for use as a secondary blanking stopper, providing spark and flame protection to the main pipe stopper (for example, when welding within a pipe, a Flameshield bag can be used to protect the pipe stopper from gases and sparks in the hot work area).
