FRP/GRP Fiberglass Reinforced Plastic pipe
Glass Reinforced Plastics, commonly known by various standards, as Fiber Reinforced Plastics (FRP), GRP, Glass Fiber Reinforced Plastic (GFRP), Reinforced Plastic Mortar Pipe (RPMP) or Reinforced Thermo-set Resin Plastic (RTRP) is an amalgamation of resin, glass fiber, manufactured using appropriate additives and treatment methods. It is a composite engineering material uniquely capable of meeting a wide variety of specific processes and end product requirements of various applications of fluid transport requirements.
Glass Reinforced Plastics pipes (GRP Pipe), it is a composite engineering material uniquely capable of meeting a wide variety of specific processes and end product requirements of various applications of fluid transport requirements.
It has a combinations of properties generally not found in any other traditional or conventional material, these include exceptionally high strength to weight ratio (have low thicknesses and high mechanical properties-with stands high pressures), superior corrosion resistance (no scaling and no buildup), maintenance free, higher hydraulic efficiency (smaller sizes), light weight (lower transportation and installation costs), higher resistance to surge pressure (more safer under worst conditions due to its low modulus of elasticity), best joining systems, excellent workability and design flexibility’s.
Thus allowing GRP piping to be used for high pressures and in very tough and rough conditions.
GRP piping system is often utilized in almost all applications to with stand aggressive service, ambient and environmental conditions. It has been successfully used in various piping systems and applications in all of the world.Specification:
—Length of single pipe: DN<250 ,L=6m ;DN≥12m ;the length can also be made according to the requirement of the user.
— Light weight, high strength, and convenient transportation and installation.
— Excellent corrosion resistant, it can be used under the condition of seawater environment for long time.
— Good low temperature resistant, it can be used under the condition of -45°C-120°C for long time.
— Smooth inner surface, its roughness coefficient is 0.0084, good conveying, and no fouling, no secondary pollution, decrease the cost of the running & maintenance.
— Fire retardant, it meets IMOA.753(18) Level-3 fire resistance class.
Main raw material
1.Resin:can according to different operating requirements choose different property resin
Main forming process
Our company use international advanced level computer control continuous fiberglass winding
forming process,according to design procedure on the mold make inner layer,inner structure
layer,resin mortar layer,outer structure layer,outer protection layer in turn,and then through the
far infrared baking sheet do heat treatment,after curing according to the standard do hydrostatic test.
Double “O” sealing ring bell and spigot,single “O” sealing ring bell and spigot,butt joint and
bell and spigot splice,flange connection etc.
Main application filed
1.Drinking water transportation pipe
2.Sewage water collecter and transportation pipe,reuse of recycled water pipe
3.Municipal water supply and drainage pipeline
4.Seawater transportation pipe and other kinds of buried pipe
