Floor (Slab) Pipe Penetration Sealing

WA-GP-SP disk compression seals, pipe though slab sealing

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.

Used in pairs, floor and ceiling, they protect against penetration of water, gas and smoke. 


Fireproofing barriers may be used to fill the space between the seals.

SP disk compression seals are a 36 psi seal with an extended pressure plate flange. Pipe penetrations up to 80 inch (2000mm) diameter pipe may be sealed.

Flange material is stainless steel. 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 axis angular deviation from the bore axis may not exceed 2°

Pressure disk seals for annular space, compensates and absorbs vibration in the pipeline.

The double pressure seal design isolates structure contact with the pipe.

Radial and Axial Pipe movement compensating seals

WA.GP-NS Disk Seals: compensates for some axial movement and 10-15 mm of angular deflection.

WA.GP.NS seals are used when settling deflection is expected between structures. E.g. short pipe runs between existing foundations and new instal at ions, where soil samples are not similar.

Max size for 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 exist. Type one is placed inside the pipe passage opening.

axial-movement-pipe-seals

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

Pipe OD and opening ID is required for sizing.

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

The rubber elastomer may be EDPM or Oil and Gas resistant NBR.

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

Axial pipe movement Seals external mount

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

They perform the same functions as Type 1.

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

Summery:

Application range: Sealing Pressure 0.1 MPa (14.50 psi). Up to 56 inch pipe.

Advantages: 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 II.

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 0.14MPa
