Pipe Penetration Seals
The Pipe Penetration Seal is designed to provide a gas and water-tight seal. Pipe Penetration Seals PTFE Lined are Rubber Expansion Joints are lined with Teflon for corrosive chemical applications. Pipe Penetration Seals PEN-SEAL Pipe Penetration Seals have been designed to assist in achieving an efficient, low-cost mechanical seal between any Electrical Conduit, Concrete, Cast Iron, Steel, Copper, or PVC/CPVC pipes passing through Walls, Floors, Tanks, Pipeline Casings, and Vaults. The PEN-SEAL, while being used to seal the gap in electrical conduit lines, will also act as an insulator. The PEN-SEAL has been designed to provide a gas and watertight seal. All sizes have been tested to withstand a hydrostatic seal up to 20 psig or 40 feet of head pressure in addition to withstanding temperatures up to 250° F.
PEN-SEAL’s standard elastomer material is EPDM, which is suitable for temperatures ranging from -40° F to 250° F. EPDM is suitable for most applications in water—above ground and direct burial—and will provide the electrical insulation where cathodic protection is required. Silicone material is also available for higher temperature applications up to 400° F. Where the PEN-SEAL may come in contact with Hydrocarbons, Oil, Gas, Jet Fuel, and miscellaneous solvents, a Nitrile material is available with temperatures ranging from -40° F to 210° F. The PEN-SEAL utilizes glass-reinforced plastic for the pressure plates and all hardware is manufactured from Steel Zinc Dichromate. For corrosion resistance, 316 Stainless Steel hardware is also available. Various applications for the PEN-SEAL:
- Wall Sleeves • Precast Concrete • Valve PitsFloor Sleeves • Mining • Offshore Oil Platforms
- Interior Piping • Marine • Telecommunications
- Noise Dampener • Water & Wastewater • Dual Containment Seal
- Electrical Contractors • HVAC • Underground Steel Tanks
- Coal Preparation Plants
- Pulp & Paper
- Power Generation
