Custom Fiberglass Pipe & Pipe Headers

Filamanet Wound PipeStandard & Custom FRP Pipe

Fiberglass reinforced polyester and vinylester pipe is a standard material for transporting corrosive liquids and is in wide use in the chemical, oil, paper, power, municipal water, sewage, and many other industrial applications.

Fiberglass pipe is often referred to as Fiberglass Reinforced Plastic (FRP), Glass Reinforced Plastic (GRP), and Reinforced Thermosetting Resin Pipe (RTRP).

The use of these products continues to grow. Bittner FRP Pipe resistance to corrosive chemical environments and cost effectiveness has proven its ability to replace carbon steel and stainless steel pipe at a lower overall cost.

Advantages of Bittner fiberglass pipe include:
  • Light weight - Fiberglass pipe weighs only about one-quarter as much as similar steel products. This reduces the cost of handling, supporting, and installation.
  • Pressure PipeStrength to weight ratio - Fiberglass pipe has a higher ratio of strength to weight than carbon or stainless steels.
  • Dimensional Stability - Fiberglass pipe can maintain the critical tolerances required of the most demanding applications.
  • Electrical properties - Standard fiberglass pipe is nonconductive.
    However, Bittner pipe offers conductive pipe and duct systems for
    applications where it is necessary to dissipate static charge
    buildup when transporting flammable fluids or gasses
