Pipe Seals & Wall Sleeves

Pipe Seals

BWM Pipe Penetration Seals have been designed to assist in achieving an efficient, low-cost mechanical seal between any Electrical Conduit, Concrete, Cast Iron, Steel, Copper or PVC/CPVC pipes passing through Walls, Floors, Tanks, Pipeline Casings and Vaults. The PIPE SEAL, while being used to seal the gap in electrical conduit lines, will also act as an insulator.

The PIPE SEAL has been designed to provide a gas and watertight seal. All sizes have been tested to withstand a hydrostatic seal up to 20 psig or 40 feet of head pressure in addition to withstanding temperatures up to 250° F.

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.

Wall Sleeves

BWM produces a full line of wall and floor sleeves. All sleeves are fabricated from steel pipe conforming to ASTM A-53. Wall collars are produced from steel conforming to ASTM A-36. Wall collars are attached to the O.D. of the sleeve by means of continuous MIG welding to achieve a watertight seal. Wall collars are normally 2-inches wide. Special widths and heights are available. BWM sleeves are designed to mate with BWM pipe seals for a leak free performance.We manufacture our own, so any special designs are welcome.
