What is FRP pipe?

The complete form of FRP is glass fiber reinforced plastic, which is a composite material consisting of a fiber-reinforced polymer matrix. Thus, FRP pipe is a pipe manufactured from FRP material by contact molding or fiber winding methods. Various types of resins, such as thermosetting polyesters, epoxy resins, phenolic resins, etc., are used to obtain specific FRP pipe properties in the final product. The most widely used reinforcement material is glass fiber "E-glass". FRP piping systems are used worldwide as a corrosion resistant alternative to metal piping. FRP piping systems are available in a variety of sizes, ranging from 1" to 144".

 

FRP pipe is manufactured by a winding process that reinforces thermosetting epoxy resins with continuous glass filaments. As the resins cure, they undergo an irreversible chemical reaction, giving them excellent resistance to temperature changes, while the glass fibers give them excellent mechanical strength. In microtunnels, steel casing is used for jacking where significant force is required. frp pipe is now widely used for this purpose because of the reduced force of hydraulic jacks, making it cost effective and also allowing longer lengths to be installed. frp can also be used for non-excavation repair methods such as slip lining. frp is resistant to corrosion and chemicals, making it an ideal material for pipes carrying such wastewater.

 

Classification of FRP pipes

According to the shape of media, FRP vessels can be divided into three categories of liquid, gas, solid tank; according to the pressure grade,can be divided into two categories of ATM tank and pressure tank; According to shape of vessel, can be divided into three categories of horizontal cylinder tank, vertical cylinder tank, rectangle tank; And PVC/FRP, PP/FRP, PVDF/FRP composite tanks.

 

Applications of FRP pipes

The use of FRP piping is increasing due to its high durability, corrosion resistance and moderate strength.FRP piping systems are used in various industries, such as

Drinking water and seawater desalination industries

Chemical, petrochemical, oil and gas industries.

Piping and ventilation ducts

Irrigation and sanitation services

Water distribution and delivery

Slurry piping

Power plants, etc.
