Pipe Through Floor Sealing

WA-GP-SP pipe though floor slab seals

pipe-penetration-floor-seals

floor-seal-for-pipe-passage WA-GP-SP are annular space seals designed for sealing  pipes, cables and conduit passing through floors and ceilings. They are polished 316L stainless for visual effect when the pipes are visible between floors.

They protect against water, gas and smoke migrations through floors and ceilings. 


Fireproof barriers may be used to fill the space between the seals to create a fireproof barrier.

WA-GP-SP pipe seals make a 36 psi seal. Pipe penetrations up to 8 inch (200 mm) diameter pipe may be made waterproof..

Flange material is stainless steel compression plates.. Sealing element disk may be EPDM, NBR, or silicone.

 

 

The advantages :

  • Prevents migration of liquids, gases and smoke, between floors.
  • Suppresses noise transfer between floors.
  • Pipeline flex is limited 2 degrees.

Annular seals for Vibration Dampening.

WA.GP-PT Pressure Disk Seal have a double seal for vibration absorption.

Sounds and vibration sometimes travel along pipes that pass through wall structures. WA.GP-PT pipe seals provide a silencing effect in these events. The double seal design isolates and insulates contact between the pipe and the opening. Noise transmission is diminished along the pipe.

Axial and Annular Pipe movement compensating seals

WA.GP-NS seals: compensates for 22 mm axial movement and 10-15 mm of angular deflection.

WA.GP.NS seals may also be installed when settling deflection is expected between structures.

Max pipe size is 300mm (12 inch) pipe.

The flexible design compensates for shear stress up to 10-12 mm acting on the pipe.

The pipe seal maintains an hydrostatic 22 psi Integrity seal. Elastomers: EDPM, NBR or Silicone.

Pipes with axial movement

WA.GP-AM type 1 is used for sealing pipes where axial movement of a pipeline may be significant. Type 1 seals are placed inside the pipe passage opening and expands against the inside diameter of the opening.

axial-movement-pipe-seals

- The seal maintains integrity up to 14 psi pressure or 33 ft. head.

- Pipe OD and opening ID is required for sizing.

- The GP- AM can accommodate pipe sizes up to 56 inch pipe (1400mm).

- The rubber elastomer may be EDPM or NBR for Oil and Gas applications.

The WA.GP-AM cannot be manufactured in a split version, the pipe must fit through the seal.

Pipes seals for pipes with axial movement through wall openings

axial-pipe-expansion-sealingWA.GP-AM type 2 external wall mount pipe seals, mount to a concrete wall and compensate for axial movement of the pipe.

They perform the same functions as Type 1.

The WA.GP-AM type 2 I cannot be manufactured in a split version, the pipe must fit through the seal.

Application range:

- Sealing pressure 0.1 MPa (14.50 psi). Pipe diameters up to 56 inch.

- Pressure sealing for pipes, Conduit, Cables penetrating a concrete wall or seal a carrier pipe through a casing.

- Seals against Liquids, Gases and Smoke.

- Allows axial movement and annular deflection of the pipe. Reduces Vibration.

Scope of delivery: Seal Elastomer, Pressure Plates, anchor bolts for external wall mounting - type 2.

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

Tightness: Tight to 0.14MPa
