FRP pipe fittings

FRP pipe fittings are a new type of pipe material composed of fiberglass reinforced plastic (FRP) and a resin matrix. It has excellent properties such as light weight, high strength, corrosion resistance, high temperature resistance, and insulation. It is widely used in municipal administration, electric power, chemical industry, petroleum, agriculture and other fields.

Main Features

Lightweight and high strength: The density of FRP pipe fittings is about 1/4 to 1/5 of steel, but its axial tensile strength can reach more than 300MPa, the specific strength is higher than steel, and it is light in weight and high in strength.

Chemical corrosion resistance: FRP pipe fittings can resist corrosion from a variety of acids, alkalis, salts and organic solvents, and are suitable for conveying corrosive media such as chemical wastewater, acidic liquids, etc.

High temperature resistance: FRP pipe fittings can still maintain stable mechanical properties in high temperature environments and are suitable for high temperature working environments.

Insulation performance: FRP pipe fittings have good electrical insulation performance, can effectively prevent current leakage and static interference, and are suitable for power transmission.

Easy installation: FRP pipe fittings are light in weight, easy to transport and install, and reduce project costs.

Long service life: Due to its excellent corrosion resistance and aging resistance, the service life of FRP pipe fittings can reach more than 50 years.

Application Areas

FRP pipe fittings have been widely used in many fields due to their unique performance characteristics:

Municipal engineering: used in water supply projects, drainage projects, rainwater projects, etc.

Electric power industry: used in power plant circulating water, desulfurization systems, etc.

Chemical industry: used to transport corrosive media, such as chemical wastewater, acidic liquids, etc.

Petroleum industry: used for oil well water injection pipes, oil and gas transportation, etc.

Agricultural irrigation: used for farmland water conservancy irrigation.

Other areas: such as large water diversion projects, chimney desulfurization, food fermentation tanks, etc.

Product classification

The structural forms of FRP pipe fittings mainly include the following:

FRP flange: used for pipe connections.

FRP elbow: used for pipe steering.

FRP tee: used for pipeline branches.

FRP four-way: used for multi-directional pipeline branches.

Y-joints and T-joints: used for specific pipe connections.

Fiberglass reducer (large and small heads): used to change the diameter of the pipe.

Classified by pressure level

FRP pipe fittings can be divided into low-pressure, medium-pressure and high-pressure pipe fittings according to the pressure level, which are suitable for transportation needs under different pressure conditions.
