3PE anti-corrosion steel pipe and 2PE anti-corrosion steel pipe are two classifications of PE anti-corrosion steel pipe. I believe that some friends will ask at this time, why is 3PE anti-corrosion steel pipe more favored by people? Let us analyze it below: In terms of structure, 3pe anti-corrosion steel pipe refers to 3-layer structure polyolefin coating (MAPEC) outer anti-corrosion steel pipe, generally used for electric resistance welded pipe, first layer epoxy powder (FBE>100um), second layer adhesive (AD)170 ~250um, the third layer of polyethylene (PE) 2.5 ~ 3.7mm, the actual operation of the three materials mixed into one, after processing to firmly bond with the steel pipe to form an excellent anti-corrosion layer; and 2PE anti-corrosion (two-layer polyethylene Pipeline two-layer PE anti-corrosion structure, the first layer of adhesive (AD), the second layer of polyethylene (PE), the two materials are integrated. In terms of price performance, the service life of 3pe anti-corrosion steel pipe is 3-5 times longer than other steel pipes, so the price of 3PE anti-corrosion is higher than that of other steel pipes. In recent years, due to the sustainable development of th...
