Pipe Through-Wall Seal System Disk Compression Seals

pipe-through-concrete-sealing

Westatlantic Class pipe seals underground or above ground

Wall pipe sealing - for multiple pipe/conduit through the same opening

WA-GP watertight systems seal pipes through drill cored and wall sleeve openings. WA-GP seals are low profile units used for thin walls, floor slabs and manhole sealing. They are only 2 3/4" thick, pressure seals to 36 psi, they require a very small seating area.

Fractional diameter pipes or large pipes may be sealed with WA-GP disk seals. Split models are available for existing pipes.

Silicone disk elements provide hydraulic sealing in fire wall applications when combined with fireproofing materials. WA-GP low profile seating profile allows both fireproofing and watertight sealing in the same wall opening.

Material Specs

  • Seal compression plates are stainless steel for maximum corrosion resistance.
  • EPDM elastomers for water applications, or NBR for oil and gas and Silicone for high temperature applications.
  • Operating pressures to 36 psi (0.25 MPa) (2.5 bar)

WA-GP seals fit all American and International pipe sizes. Inquiry at Westatlantic with your pipe sizes, we will provide seal models required, opening size and delivered pricing.


WA-GP Models

WA.GP-SR non-split models for single pipe or conduit penetrations.

watertight-pipe-seal

WA.GP-SR pipe seals, seal pipe penetrations for fractional and small pipe diameters, or larger pipes.

Low profile thickness (only 2 3/4 inches), make them an effective choice for pipe penetrations through manhole walls and thin concrete slaps. WA.GP.SR pipe seals may be used in drill cores or wall sleeves.

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

gpw

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 existing pipes.

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 required.

WA.GP-W and WA.GP-WK models are 36 psi watertight seals. they provide water-tight, gas-tight, smoke-tight sealing for pipe, cable or conduit through concrete walls.

Seals consists of an elastomer disks and two stainless steel compression plates. They are annular space seals used for steel pipes, PVC, PE, Ductile Iron and power cables. Pressure seal for up to 36 psi (2.5 bars) (80 foot head).

Large annular space seals:

WA.GP-SD seals are used where large annular space between the pipe and wall opening exist, or a small carrier pipe through a large casing exist. They are used to seal an opening when a large flange must pass through a wall which requires an opening larger than normal.

Split model WA-GP-SD.

  • Split Disk-seals for pipes that already exist.
  • 2.5 to 5 bar (36 -72 psi) pressure seals.
  • Multi pipe sealing through same opening, with a large annular space..
  • Sealing for large annular spaces.

WA-GP-W compression pipe seals
Silicone temperature withstanding elastomers with stainless pressure plates

WA.GP-W compression seals and Modular Hi-Temp pipe seals with silicone rubber elastomer, for high temperature applications.

Silicone elastomer seals are used for sealing steam pipes or other high temperature piping projects. Silicone pressure seals may be used with fires top materials through the same wall penetration.

WA-GP-W-Silicone watertight seals may be used for single pipe entries or multi pipes through the same core drill or pipe sleeves.

 


Non-Metallic pipe seals - through wall compression seals

Pipe casing end seals - or Special requirement 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.

dielectric-seals-pipe-casing

Non - Metallic compression seals may be used for non centered pipes by off setting 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, with stainless steel compression plates. The sealing assembly may be a split version for pipes or conduit that already exist. A split version is used when long pulls are involved, for conduit or pipe after that penetrate the wall.

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 °.
