We produces polyvinyl chloride (PVC) composite pipes and joints integrated and reinforced with fiberglass reinforced plastics (FRP) and pre-fab products (by dispatching supervisors).
AV pipes
- 1.Hard PVC pipes
A special method exclusively for the ASAHI AV series is employed to eliminate residual stress from the pipe. - 2.Treated surface
The pipe surface is treated to increase the adhesiveness of the primer. - 3.Special primer
A special primer that bonds the hard PVC tube with the FRP layer is adopted. - 4.FRP layer
It is reinforced with lamination created by impregnating glass fibers with polyester resins. - 5.Surface finish layer
This finish layer is made of a corrosion-resistant polyester resin.
Features of FRP-reinforced PVC products
- Superior in chemical resistance (Ideal for plants handling acids, alkalis or halogens)
- A high level of mechanical strength (Excellent impact-resistance strength thanks to massive pressure capacity)
- Good heat resistance (May be used for long-term under high temperature conditions)
- A low coefficient of linear expansion (around half that of PVC)
- No risk of exterior corrosion or electric corrosion (perfect insulator)
- Lightweight
- Easy to work
- SU type / Standard (maximum temperature for use: 90 deg. C) It is a reinforced by FRP resin layer prepared with a U-PVC pipe and fittings.
- GU type / High Grade (maximum temperature of use: 95 deg. C) By adding to reinforce the FRP layer, it may be used under high-temperature and high-pressure conditions.
