The wall structure of fiberglass reinforced plastic (FRP) pipes is divided from the inside out into: FRP inner lining layer, FRP secondary lining layer, FRP winding layer, and FRP external protective layer. For the production of FRP pipes, the far-infrared deep curing process is very important. It is to perform far-infrared deep curing treatment on FRP pipes, thereby improving the curing degree of the inner lining layer and the corrosion and temperature resistance performance of the pipes.
