Canvas Inflatable Pipe Air Bags

Flexible canvas-covered inflatable air bags for temporarily sealing and testing pipes where access is restricted. Available for pipe diameters from 50mm up to 4,000mm, with a choice of inflation valves and hose lengths.

Product overview

Canvas Inflatable Pipe Air Bags provide a practical solution for temporarily sealing pipelines during inspection, maintenance, testing and repair work.

Each air bag combines a durable canvas outer cover with an internal rubber bladder. When deflated, the flexible construction allows the bag to pass through openings considerably smaller than the pipe being sealed. Once correctly positioned inside the pipe, it is inflated to form a temporary seal against the internal pipe wall.

The range is suitable for applications across drainage, sewerage, utilities, petrochemical processing, food production, mining and general industrial maintenance.

A wide selection of sizes is available for nominal pipe diameters from 50mm to 4,000mm. Inflation pressure and allowable back pressure vary according to the selected size and must always be checked before use.
