Pipe Passage Through Concrete Walls

Watertight Sealing - Westatlantic Class - Systems.

Compression Seals for fractional pipe diameters or large pipe diameters.

Multiple pipes and conduit sealing through the same wall opening, drill cored walls or cast in wall sleeve assembly for new walls.

Material Specs:

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

Fits all American and International pipe sizes.

Split compression models seals used for for existing pipes

watertight-pipe-sealWA GP-SR non-split or WA GP-SR Split models for existing pipe.

WA.GP-SR pipe seals are used on fractional and small pipe sizes. The seating area required is only 2 1/4 inches, making them an effective choise for small diameter manholes or thin wall chambers.

WA.GP.SR seals may be used on Large pipe diameters with large or small annular spaces. The seal size matches field conditions. Waterproof pipe through wall penetrations.

Pressure Seal Diameter range: up to DN 3000 for large pipes
Maximum operating pressure: 36 psi (0.25 MPa) (2.5 bar)
Material: Stainless steel - 304 - 316
Operating temperature: EPDM (-30 ° C - + 100 ° C), -NBR (-20 ° C - + 90 ° C), SILICONE (-55 ° C - + 230 ° C)

 

For existing pipes use WA.GP-SR Split model Compression Seals.

dis-seal-for-a-existing-pipeSplit Models provide pipe sealing for existing pipes or conduit.

WA.GP-SD model pipe compression seals are used where large annular space between the pipe and wall opening.

Split models for existing pipes or non split for new pipe penetrations.

  • 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.

Multi-Pipe / Multiple Conduit Sealing through the same wall opening.

Multi-port WA-GP-W models or Multi-port WA-GP-WK split models.

Compression seals, WA.GP-W multiple sealing models may be used for sealing penetrations in new walls. WA.GP.WK (split) models are used for eisting pipes.

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 opening, is the opening size and the total pipe or conduit through the opening.

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

Compression seals consists of an elastomer ring 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.

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).

dielectric-seals-pipe-casing

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


Rectangular or square openings - through wall pipe and conduit sealing

WA-GP-WP models, Stainless Steel compression Plates. The sealing assembly may be a split version for pipes or conduit that already exist or when long pulls are involved.

Water tight sealing for multi pipe or conduit clusters.

 

 

 

 

 


EDPM, elastomer seals for water applications, NBR elastomer 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 °.
