| Industrial pipe >> RPMP Pipe |
RPMP pipe (fiberglass reinforced plastic mortar pipe) is wound with glass fiber and its products as reinforced materials, with unsaturated polyester resin as matrix and quartz sand-inorganic non-metallic grain materials as filling. The process includes fixed length winding, centrifugal casting and continuous winding .
Production range:
Diameter DN50mm--DN4000mm; Pressure 0.1Mpa--3.5Mpa
Executive standard:
Glass fiber reinforced plastic mortar pipe GB/T21238-2007
Application field:
Be widely used in fields like: oilfield, chemical industry, municipal water supply and drainage, water conservancy construction, power plant, ports, sewage treatment plant, the papermaking, tanning, medicine engineering and other high water consumption projects.
Performance characteristics of products:
Excellent physical property, light weight, and high specific strength;
Good corrosion resistance performance, long service life;
Very smooth internal wall, excellent hydraulic characteristics;
Easy installation and low comprehensive cost;
Good insulating performance;
Low heat loss;
Stable chemical structure, no secondary pollution;
Good sealing performance.
