Floor (Slab) Pipe Penetrations
WA-GP-SP disk compression seals, pipe though slab sealing
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°
GP-PT Pressure Disk Seal
Pressure disk seals for annular space, compensates and absorbs vibration in the pipeline.
The double pressure seal design isolates structure contact with the pipe.
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.
Opposing Structure settlement compensating 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
They perform the same functions as Type 1.
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
