Yellow 3PE anti-corrosion steel pipe
details
Introduction of Yellow 3PE Corrosion Resistant Steel Pipe
Yellow 3PE corrosion-resistant steel pipe for a buried pipeline life is critical, the same material pipe, and some buried in the underground for decades without corrosion, and some years to leak. It is because they use a different outer coating.
3PE anti-corrosion generally consists of three-tier structure:
The first layer of epoxy powder (FBE> 100um)
The second layer of adhesive (AD) 170 ~ 250um
The third layer of polyethylene (PE) 2.5 ~ 3.7mm
The actual operation will be three kinds of materials blend into one, after processing to make it firmly with the steel pipe to form an excellent coating. The processing methods are generally divided into two types of winding and round-type coated.
Yellow 3PE anti-corrosion anti-corrosion layer of the advantages
Yellow 3PE anticorrosive coating is the bottom layer of contact with the steel surface is epoxy powder coating, the middle layer with branched functional groups of copolymer adhesive. The surface layer is a high-density polyethylene anticorrosive coating. Yellow 3PE anti-corrosion coating that is (three-tier polyethylene anti-corrosion coating), is the European 2PE coating and widely used in North America epoxy powder coated steel pipe coating (FBE) cleverly combined to produce a new anti-corrosion Steel pipe coating. Has been recognized and used in the world has been more than a decade.
Yellow 3PE anti-corrosion quality test methods:
First of all, the corrosion of steel pipe inspection, a variety of conditions to test the steel pipe, making it in line with the conditions of production of steel pipe insulation. Check the pipe is not corroded, check and remove the embroidery on the pipe. The next step is to rust after corrosion of steel pipe sets in the polyethylene casing, the wear pipe molding. However, after the head repair, in which the injection of polyurethane foam, to fully fill the gap, so that full filling. Inspection of anti-corrosion steel pipe, the completion of the production of finished steel pipe insulation test.
