Performance characteristics of engineering plastics and modified plastic pipes and their main application areas:
Pipe is one of the main products processed by plastic raw material extrusion molding. The outstanding advantage of plastic pipe is that the relative density is small, which is equivalent to 1/4-1/7 of metal; electrical insulation performance and chemical stability are excellent; installation and construction are convenient, maintenance is easy; unit energy consumption is low. However, compared with metal, its mechanical properties are lower, the operating temperature range is narrower, and the expansion and contraction deformation is large. People are constantly making up for the lack of performance of the above materials through chemical or physical modification methods, and expanding the application fields of plastic pipes through the combination of polymers and other materials.
The use of plastic pipes is to transport liquids, solids, gases, and as wires, cable jackets, and structural materials. The main application areas of plastic pipes at home and abroad are: drinking water pipes, building water pipes, building drainage pipes, buried drainage pipes, gas pipes, sheath pipes, agricultural pipes, industrial pipes. Housing construction, environmental protection and governance, agricultural water-saving irrigation, transportation, communications, water conservancy, energy and other infrastructure projects make water conservancy pipes have a very broad market.
