GRP pipe or Glass Reinforced Polyester Pipe (GRP) is a pipe that uses polyester resin, glass fiber filament reinforcement, and silica sand as the main raw materials. GRP pipe has a property of good corrosion resistance, rustproof, lightweight, and useful life of longer than 50 years.

Manufacturing technology that Thai GRP uses is Filament Winding. It is a system that uses modern technology to design and control continuation of winding angle and number of layers in winding glass fiber filament reinforcement enabling quality control in manufacturing each pipe in terms of stability, stiffness, and deformation as well as pressure load to comply with international standards.

Advantages of GRP pipe

• Good corrosion resistant by chemicals which can be buried underground without any rust.
• Lighter when compared with steel pipe and cement pipe of the same size; easy to transport and lower installation cost.
• Inner surface lining of the pipe is smooth causing low friction loss and energy saving in transporting water.
• Pipe is strong and flexible providing good resistance to external compressive force and internal pressure.
• Longer useful life compared with steel pipe or cement pipe.
• Thai GRP pipe is gasket bell and spigot joint with double seals. Pipes can be pushed to connect without using any fittings, saving a lot of time and expense. Pipe length can be ordered in 4 meters, 6 meters, 9 meters or 12 meters according to using.
• Furthermore, GRP pipe can be manufactured using food grade resin to be used with drinking water of food industry.
