Fiberglass pipe and fittings

Fiberglass pipes and components are a very good alternative to metal equipment inadvanced industries because of their unique properties, such as excellent corrosion resistance as well as high strength bonding, for use in chemical and aggressive weather conditions. The pipes made by this technology are more economical compared to corrosion resistant steel pipes and are more robust compared to thermoplastic tubes (polyethylene, PVC, etc.). This technology generally uses fibers as reinforcements and resins as matrices.

applications

The application of fiberglass pipes and fittings are in the fields of energy, especially the oil, gas and petrochemical industries, chemical products, water and sewage, power plants, melting of metals, sea and offshore industries, have been found abundantly and Among these, the following can be mentioned:

  • Water and wastewater collection and transmission lines
  • Pipelines for the collection and transmission of crude oil and gas
  • Firefighting pipelines
  • Industrial water and wastewater pipelines
  • Desalination systems
  • Seawater transmission pipelines
  • Cooling water systems
  • Irrigation and drainage systems
  • Fiberglass poles for transmission lines
  • All transfer pipelines inside ships and berths
  • Chemical and corrosive transport pipelines

Based on type of fiber and resin, these materials are classified as:

CFRP

Tubes and parts made from carbon fiber and thermoset resin

GRE

Tubes and parts made from glass fiber and epoxy resin

GRVE

 Tubes and parts made from glass fiber and vinyl ester resin

GRP

 Tubes and parts made from glass fiber and polyester resin
