AIR BAGS General function and application: PE™s inflatable air bags, for low pressure applications, allow safe air or water testing of pipes and drains, as well as stopping gas or liquid flow along the line. Manufacture Our’s air bags are made by covering a natural rubber bladder with either proofed canvas or nylon. This construction allows the deflated bags to be passed through quite small holes in the side of the pipe. To suit pipe sizes up to 96” (2400mm) and in special circumstances larger bags can be made. Application Our’ s air bags can be used for a number of applications including: pipe testing, oil pipeline maintenance, gas pipeline maintenance, and drain testing. It is generally accepted that the pressure which a bag will hold back depends on five factors: 1. 2. 3. 4. 5. The surface of the pipe into which the bag is to be inserted. The frictional resistance of the bag cover material. The total area of contact between bag and pipe. Whether or not a bag is supported. The pressure inside the bag itself.

It is worth noting that any slight physical support will dramatically increase the holdback pressure. Double length bags with restraining loops to which hawsers can be attached are also available. Provided these are properly anchored these bags whose safe working pressure is twice that of standard bags will hold back pressures up to 75% of their safe working pressures. PE air bags come with a choice of Brass & Plastic Taps or a Schraeder Valve and a standard hose/tubing of approximately 6ft length on sizes 2” to 18”, and approximately 4’ 3” length on sizes 20” to 84”. However, the hose/tubing...
