One of the differences between 3PE anti -corrosion steel pipes and plastic pipes: different meanings.
Plastic pipes, also known as plastic composite steel pipes, steel -plastic pipes and plastic composite steel pipes. The steel pipe is used as a substrate, and high -pressure polyethylene or epoxy resin glue is used as a key anticorrosive raw material. , Rolling, impregnating, and liposuction processing, the surface welding in the steel pipe has a high -pressure polyethylene anticorrosive layer or inner and outer surface welding with an epoxy anti -corrosion layer; and 3PE anti -corrosion steel pipe refers to the three -layer isoprene rubber coating external anticorrosive steel pipe. The mother material can be a seamless tube, a spiral tube, or a straight seam welded pipe. Its anticorrosive structure is one layer of epoxy powder, two layers of adhesives, and three layers of polyethylene.
The difference between 3PE anticorrosive steel pipe and plastic pipeline: The performance characteristics are different.
Plastic pipes, because of its production process and anticorrosive raw materials, so that it has excellent corrosion resistance and high and low temperature resistance. Its excellent insulation performance can be used as a protective tube for cables. If the interference is strong, if the plastic composite steel pipe is used as a cable protective pipe, it can reasonably block the external signal interference; the rolling bearing pressure is good, the work pressure reaches 5MPa; the hairless edges, the wall is clean, and can be used as a cable layer.
Because of its raw materials and production processes, 3PE anticorrosive steel pipes make it use long, large content, good reliability, and anti -aging. Under all normal operating temperature and work pressure, the use period can ensure more than 50 years. Long -term operation still operates. It can save great resources and significantly reduce energy cost fees; in addition, it also has a strong moisture -proof and anticorrosive ability, which can resist the chemical corrosion of oil and gas, vaporized vapor, and artificial gases. There is any degradation effect. In addition, 3PE anti -corrosion steel pipes are also light weight, convenient operation, and simple engineering construction. It can be immediately buried in the ground or water. In the frozen soil layer.
