Mechanical wound FRP pipe is a kind of light weight, high strength and corrosion resistant non-metallic pipe. It is made of resin fiber reinforced by special technology. This kind of pipethe advantages of anti-corrosion performance, anti-leakage performance, heat insulation performance, light weight, high strength, long life, strong designability, small fluid resistance, easy installation, low comprehensive cost and so on. It can be widely used in petroleum, chemical, rmaceutical, electric power, papermaking, urban water supply and drainage, factory sewage treatment, seawater desalination, gas transportation, mining and other industries. In recent years, China's FRP pipe production has developed rapidly, the of years on the increase, the scope of application and departments are increasingly wide. Connecting parts: socket type, butt type, flange type, o-ring type elbow pipe, t-pipe, reducing pipe, welding flange and other FRP pipe from the production process mainly include the following categories: pure FRP pipe, sand pipe, high pressure pipe, heat insulation pipe. FRP pipe mainly applied in the following fields: petroleum pipemical pipeer pipermaceutical pipeermaking pulp, urban water supply and drainage pipeustrial sewage pipewater desalination pipe transmission pipeural gas transmission pipe.
