Brief introduction of FRP flange: production of various specifications series of FRP flange, FRP elbow, FRP tee, FRP cross, FRP reducer (FRP size) and other FRP pipe fitting products or FRP composite pipe13081807766 Order hotline: 13081807766
Brief description: production of FRP flanges, FRP elbows, FRP tees, FRP crosses, FRP reducers (FRP size) and other FRP pipe fittings or FRP composite pipes
The manufacture, inspection and acceptance of FRP flanges are in accordance with HG / T21633-1991 "Glass Steel Pipe and Fittings" standard. Flange connection dimensions are in accordance with HG20592-1997, HG20615-1997, HGJ44-1991, HG5010-1958, ASME B16.5-1996, ANSI B16.5-1988 standards, or according to user requirements.
2. Prepare raw materials
The specifications and models of the raw materials used are determined according to the working conditions. After the raw materials enter the factory, they are inspected and an inspection report is issued.
4. Pipe prefabrication
According to the design specifications, connect the flange to prepare the flange mold, clean the oil and dust on the mold surface, and apply the release agent.
5, making lining
Brush the prepared gel coat resin on the mold, and then spread the surface felt and chopped felt after gelation, and fully roll, there should be no bubble cracks.
After the lining is cured, a low-pressure contact molding process is adopted, and alkali-free chopped fiber or glass cloth is laid. Each layer should be fully rolled with a pressure roller to reach the designed size.
Lining is the same.
