Watertight Pipe Passage Through Walls

Building connection sealing systems from Westatlantic.

Disk Compression Seals may be used for fractional pipe diameters or large pipe diameters.

Seal single or multiple pipes through the same wall opening. Split versions for existing pipes.

Material Specs:

  • Compression plates stainless steel, for maximum corrosion resistance.
  • Elastomer rubbers may be EPDM for water applications, or NBR for oil and gas.
  • Silicone for high temperature applications.

For all American and International pipe sizes.

WA.GP-SD for large annular space.

  • Split Disk-seals for pipes that already exist.
  • 2.5 to 5 bar (36 -72 psi) pressure seals.
  • Multi pipe sealing through same opening.disk-seal-for-pipe-through-a-wall
  • Sealing for large annular spaces.
  • Sample Installation, tighten nuts on the sealing assembly.
  • Only ordinary wrenches required.

Non-Metallic dielectric pipe through wall compression seals

Pipe casing end seals

WA-GP-P disk compression seals are 14 psi seals. WA-GP-P-DL models are 28 psi Seals. They fit pipes from 3 inch up to 120 inch, (3000mm).

Non - Metallic compression seals may be used for non centered pipes by varing the port location in the seal or have multi port openings for several pipes, cables through the same opening.

When used as end seals the port opening axially accommodates the leg height for the pipe/casing combination.

 


Application range:  Sealing pressure 0.1 MPa (14.50 psi). WA-GP- P-DL models (double seals) seal against of 29 psi hydronic pressures. May be used up to 120 inch pipe.

Advantages: Pressure sealing for pipes, Conduit, Cables that penetrate a concrete wall. Pressure sealing for end seals on a casing carrier pipe.  Seals against Liquids, Gases and Smoke. Reduces Vibration.

Scope of delivery: Seal elastomer, Non-metallic (Nylon) pressure plates, compression bolting. Seal elastomers may be: EDPM (-30 C to + 90 C) NBR (-20 C to +90 C)

Material: Pressure plates - corrosion resistant stainless steel V2A (AISI 304L); (V4A (AISI 316L) on request). Rubber: EPDM: -30C - +100C, NBR: -20C - + 90C

Tightness: Tight to 0.1MPa – 0.2MPa


Multi-Pipe / Multiple Conduit Sealing through the same wall opening.
WA-GP-W models or WA-GP-WK split models

Compression Disk seals, WA.GP-W multiple sealing models may be used for sealing penetrations in new walls or pipe through existing wall openings. GP systems are available for outside pipe diameters from 6mm to 3000mm (1/8 to 120 inches).

The only limiting factor on the number of pipes or conduit that may be sealed through the same hole, is the opening size and the total pipe outside diameters through the opening.

WA.GP-W and WA.GP-WK models are 36 psi water tight seals. Water-tight, gas-tight, smoke-tight seals for pipe, cable or conduit through concrete walls, tanks and hydrological structures.

Compression disk-seals consists of an elastomer ring or grommet and two compression plates made of stainless steel.

Compression disk annular space seals may be used for steel pipes, PVC, PE, Ductile Iron and power cables. GP metallic pressure seals, provide 36 psi (2.5 bars) (80 foot head) seals.

To calculate size of the multi-pipe disk seal required provide:

  • Pipe/conduit outside diameters and number of penetrations.
  • Type of elastomer EDPM, NBR, Silicone. EDPM normal, NBR for applications involving Oil/Gas and Silicone for temperature applications.

Through wall pipe sealing for square or rectangular concrete wall openings
WA-GP-WT models, Stainless Steel compression Plates.

 

 

 

 

 


Use EDPM, elastomer rubber for water applications, Oil resistant NBR, for hydrocarbon applications or Silicone elastomers for heat affected pipes. Sealing to 36 psi (80 ft. head)

  • Seals are designed for all dimensions.
  • Provides watertight tight seals to 36 psi.
  • Prevents migration of liquids, gases and smoke.
  • Reduces noise.
  • Split version fir existing pipes, cables (etc.).
  • Flexibility sealing.
  • Angular deviation of pipe axis from the bore axis may not exceed 2 °.

WA-DL.GP Models providing 72 psi sealing (160 foot water head)
