One of the differences between 3PE anticorrosion steel pipe and plastic coated pipe: the meaning is different.
Plastic-coated pipe, also known as plastic-coated composite steel pipe, steel-plastic pipe and plastic-coated composite steel pipe, steel pipe as the base material, the selection of hot dip forming of high-pressure polyethylene or epoxy resin adhesive as the key anticorrosive raw materials, and subsequently through the spray painting, rolling, impregnation and liposuction processing technology, welded to the inner surface of the steel pipe with a high-pressure polyethylene anticorrosive layer or welded to the inner surface of the inner and outer surface of the epoxy corrosion protection layer; and the 3PE anticorrosive steel pipe refers to the three-layer isoprene rubber Coating external anticorrosion steel pipe, its parent material can be seamless pipe, can be spiral welded pipe, can also be straight seam welded pipe, its anticorrosion structure is a layer of epoxy powder, the second layer of adhesive, three layers of polyethylene.
3PE anti-corrosion steel pipe and plastic coated pipe difference of two: performance characteristics are not the same.
Plastic-coated pipe, because of its production process and anticorrosion raw materials, so that it has excellent corrosion resistance and resistance to high and low temperature performance; its excellent insulation properties, can be used as a cable line protection pipe, leakage basically will not appear; strong anti-interference, if the plastic-coated composite steel pipe as a cable protection pipe, can be reasonably shielded from the outside world signal interference; rolling bearings with good pressure strength, the working pressure reaches 5Mpa; no burr! The wall is smooth and clean, can be used as cable laying casing.
And 3PE anti-corrosion steel pipe because of its raw materials and production processes, so that its long service life, content, reliability, aging resistance, in all normal operating temperatures and working pressures, the use of the period of time to ensure that more than 50 years, long-term operation can still save a lot of resources, significantly reduce the cost of energy; in addition to having a strong moisture-proof and corrosion-resistant ability to resist the oil and gas, vaporization of vapors, artificial gases and other Chemical corrosion, compounds in the soil layer does not have any degradation effect on the pipeline, in addition, 3PE anticorrosion steel pipe is also light weight, easy to operate, easy construction, can be immediately buried in the ground or water, without additional trench, in certain natural environments can also be buried directly in the permafrost layer.
