| Glass-reinforced Plastic Pipe (FRP) |
| Fiber winded glass-reinforced plastic pipe is mainly used in fields of petroleum, chemical industry, metallurgy and medicine etc. It has advantages such as light weight, strong corrosion resistance and convenient installation and maintenance. |
| 1. Struture of Tube Wall ¡¡¡¡ |
| Li'an brand glass pipe products integrates three aspects of factors of economical efficiency, producibility and practicability. It adopts internationally advanced structural level of tube wall according to long-term application at home or abroad. |
| 2¡¢Main Shaping Process |
| Controlled by computer, make liner and process defoaming treatment according to the requirements. After gelation, use liner layer to wind structural layer according designed linear and thickness and outer protection layer is laid at the last step. If required, we can add antiflammability agent, ultra-voilet protectant and other additives with special functions or real materials and so on, or resin of raw materials and auxiliary materials, fiberglass felt and continuous GRP fiber etc. |
(1) Raw Materials and Auxiliary Materials Resin, chopped strand, continuous fiber glass and other auxiliary etc.
