FRP pipe is made of unsaturated polyester resin, continuous glass fiber yarn and glass fiber mat, the pultrusion process control, and has high strength, light weight, antiseptic, beautiful, impact resistance and other characteristics. It is widely used in petroleum, chemical industry and other corrosion environment of stairways and railings, operating platform, corridor, supporting frame, etc.
FRP gratings with light weight, high strength, corrosion protection, prevent slippery, ageing resistance, impact resistance, opening, cutting character such as convenient and not scattered, widely used in petroleum, chemical, electric power, electroplating, sewage treatment and other industries work platforms, equipment platforms, stair tread, trench cover, pier aisle, etc., is in corrosion environment is the ideal substitute of traditional metal grille.
FRP pipe is a kind of linear FRP pultrusion profiles production process, this process is irreversible, it can’t be melt or forming again again.
This is different from PVC (polyvinyl chloride), PVC under the action of thermal deformation.
Glass fiber reinforced plastic pipe used in FRP pultrusion profiles is thermosetting resin, PVC is a thermoplastic resin.
In pultrusion process, under the effect of heat and pressure, the thermosetting resin and glass fiber to form a new kind of inert materials, it is not affected by temperature.
Temperature increased to 350 ° F (176 ° C) ago, pultrusion will not alter physical properties of glass fiber reinforced plastic, and polyvinyl chloride (PVC) in the temperature reaches 155 ° F (69 ° C) is not stable.
