Project Description

Pipe Penetration SealsPipe Penetration Seal

The Pipe Penetration Seal is designed to provide a gas and water-tight seal. Pipe penetration seals PTFE lined with Teflon for corrosive chemical applications. 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.

Piping seals, while being used to seal the gap in electrical conduit lines, will also act as an insulator. The pipe seal has been designed to provide a gas and watertight seal. Sizes are tested to withstand a hydrostatic seal up to 20 PSIG or 40 feet of head pressure, in addition, to withstand temperatures up to 250° F.

Standard elastomer material is EPDM, which is suitable for temperatures ranging from -40° F to 250° F. EPDM is ideal for most applications in water—above ground and direct burial—and will provide the electrical insulation where cathodic protection is required.

The silicone material is also available for higher temperature applications up to 400° F. Where the pipe seal may come in contact with hydrocarbons, oil, gas, jet fuel, and various solvents, a nitrile material is available with temperatures ranging from -40° F to 210° F.

Piping seals 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 pipe seal

  • Wall Sleeves • Precast Concrete • Valve Pits
  • Floor 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

Pipe Seal

The Pipe Seal provides cost-effective and specific protection pipes and passage through walls and floors for twenty psig. Wall sleeves are available. Selection starts with materials. Three sorts of rubber and two types of metal hardware are available.

EPDM is that the correct choice for many applications. However, an organic compound is best if the seal is also exposed to hydrocarbons. Likewise, chrome steel hardware may be used rather than galvanized hardware. Furthermore, polymer is the choice for high-temperature applications.

When selecting materials, you identify which model and the way several links are going to be needed. Help may be provided in filler or check our filler tables or our filler calculator spreadsheet.

Rubber expansion joints and Metal expansion joints. are often used on a pipe system where pipe seals are used.

What is a Pipe Seal?

The sizing tables recommend hole sizes for numerous sorts and sizes of piping, in conjunction with the Pipe Seal model and, therefore, the range of links required. The sizing program is best used once the opening scale used isn’t recommended within the sizing tables.

The PipeSeal provides an economical and sure method of sealing pipes and conduit through walls and floors for 20 psig. Wall sleeves are also available.

Choice starts with materials. Three types of rubber, and two types of metal hardware are available. For most applications, EPDM is the proper choice, but Nitrile is best if the pipe seal may be exposed to hydrocarbons. Stainless steel hardware can also be used instead of galvanized hardware in areas where corrosion is a tougher problem. Additionally silicone is the choice for high temperature applications.

First choose materials. Next determine which model and how many links will be needed. Furthermore, we can provide help with sizing. The sizing tables suggest hole sizes for various types and sizes of piping, along with the PipeSeal model and number of links required. The sizing spreadsheet is best used when the size of the hole used is not what we have suggested in the sizing tables.

What are the functions of a Pipe Seal?

The following main criteria for the development of pipeline joints are:

  • Leak tightness from both infiltration and exfiltration
  • Ease and reliability of jointing on site
  • Long term durability

The first two requirements have been a focus for many years but now long term durability is becoming increasingly important as modern pipeline networks are often required to perform in excess of 100 years.

Piping Seals

Piping seals forms a mechanical rubber seal between pipes going through walls, floors, vaults, tanks, and pipeline casings and makes a watertight seal between a pipe and a wall hole. It can also be used to seal a gap between an inner pipe and an outer pipe sleeve or pipeline casing. The pipe seal also will seal the gap between the electrical conduit and the outer conduit, or between the electrical conduit and the wall hole it passes through. Our pipe seal is designed to form a hydrostatic seal of up to 20 psig and up to 40 feet of head.

The PIPESEAL, in addition to its sealing properties, helps absorb vibrations, shocks, and sound waves. It also insulates the inner pipe from all other outer structures, including outer pipe sleeves, pipeline casings, walls and tanks. The pipe seal is made from synthetic rubber with heavy duty plastic pressure plates, which are resistant to sunlight and ozone. All bolts and nuts are plated with an anticorrosive Schedule 40 or Standard Weight Pipe corrosive coating. Stainless steel nuts and bolts are also available.

Piping seal installation instructions

1. Properly select the size of the Pipe-seal required to seal the penetration using the Sizing Charts on pages 2 through 7.

2. Wrap the Pipe-SEAL around the pipe and connect the ends.

3. Slide the Pipe-SEAL into position.

4. Tighten each bolt on each pressure plate about 2–3 turns, going around the pipe (do not cross-tighten bolts) until a proper seal is formed. A socket or offset wrench for 5/16, 1/2, 3/8, 9/16, 3/4, or 1-13/16” bolts will handle all installations.
