PIPE SEAL standard elastomer material is EPDM, which is suitable for temperatures ranging from – 40° F to 250° F. EPDM is suitable for most applications in water – above ground and direct burial – and will provide the electrical insulation where cathodic protection is required.
Where the PIPE SEAL may come in contact with Hydrocarbons, Oil, Gas, Jet fuel and miscellaneous solvents, a Nitrile material is available with temperatures ranging from -40° F to 210° F.
The PIPE SEAL utilizes glass-reinforced plastic for the pressure plates and all hardware is manufactured from Steel Zinc Dichromate. For extremely corrosive environments, Stainless Steel hardware is available upon request. The BWM Company’s PIPE SEAL is made from synthetic rubber with heavy duty plastic pressure plates, which are resistant to sunlight and ozone. All bolts and nuts are plated with an anti corrosive coating. Stainless steel nuts and bolts are also available.
The BWM Company’s PIPE SEAL forms a mechanical rubber seal between pipes going through walls, floors, vaults, tanks, and pipeline casings and makes a watertight seal between a pipe and a wall hole. The BWM Company’s PIPE SEAL can also be used to seal a gap between an inner pipe and an outer pipe sleeve or pipeline casing. BWM Company’s PIPE SEAL also will seal the gap between the electrical conduit and the outer conduit, or between the electrical conduit and the wall hole it passes through.
The BWM Company’s PIPE SEAL is designed to form a hydrostatic seal of up to 20 psig and up to 40 feet of head. The BWM Company’s PIPE SEAL, in addition to its sealing properties, helps absorb vibrations, shocks and sound waves. It also insulates the inner pipe from all other outer structures, including outer pipe sleeves, pipeline casings, walls and tanks.
