Product Description

Fiberglass Reinforced Plastic (FRP) Winding Process Pipe

FRP pipe is a lightweight, high-strength, corrosion-resistant non-metallic pipe. It is the glass fiber with resin matrix wound layer by layer onto the rotating core mold according to the process requirements. The wall structure is reasonable and advanced, which can give full play to the role of the material and improve the rigidity under the premise of meeting the use of strength to ensure the stability and reliability of the product. FRP with its excellent chemical corrosion resistance, lightweight and high strength, non-scaling, seismic, and ordinary pipe and cast iron pipe compared with the use of long life, low overall cost, fast installation, safety and reliability, etc., accepted by the user. FRP pipe applications involve petroleum, chemical, water supply and drainage industries.

Connection of FRP pipe

1, FRP pipe commonly used connection method has five kinds.

Wrapped butt, take on the rubber connection, flange connection and socket coupling (with rubber ring sealing socket connection) the first three methods are mostly used for fixed connection between the pipe and the pipe, flange connection is used for frequently disassembled parts, and socket coupling is mostly used for the connection between the underground pipeline. (See figure below)

Wrap butt method is suitable for large-diameter pipe bending parts of the connection and on-site repair, to undertake the rubber connection method is suitable for fixed-length pipe connection (but there is a corrosion-resistant layer of pipe can not be used) pipes and pumps to connect, due to vibration, the application of flexible joints in order to reduce the deformation of the pipeline and fittings parts.

2, Pipe accessories

Fiberglass reinforced plastic pipe accessories are elbow, tee, flange-type joints, T-type joints, reducers, etc., all kinds of fiberglass reinforced plastic pipes have corresponding accessories to match see the following chart.

Main Molding Process

Controlled by computer, the inner lining layer is made and defoamed according to the requirements; after the inner lining layer is gelatinized, the structural layer is wound according to the designed line shape and thickness; finally, the outer protective layer is laid; if requested by the users, flame retardant, ultraviolet ray protection agent and other special functional additives or fillers can be added.

Product Feature

Key Features of FRP Pipes

Superior corrosion resistance

It can resist the erosion of various chemical media such as acids, alkalis, salts, solvents, etc., and does not rust or electrochemical corrosion.

Lightweight and high-strength

The weight is only about 1/4 of the same specification steel pipe, but the strength is high, and the specific strength (strength/density) is close to or even exceeds that of steel.

Excellent interior wall performance

The inner wall is very smooth, with low friction resistance (low roughness), and it is not easy to scale and breed microorganisms.

Design flexibility and long life

Customized production to meet specific needs by changing resin systems, fiber types and ply designs; The overall design has a long life, usually up to 50 years or more.

Good comprehensive performance

It has the characteristics of insulation, non-magnetic, thermal insulation, and fatigue resistance.

Main raw and auxiliary materials

Resin, glass fiber mat, continuous glass fiber, etc.
