Did you know? Do not just heard this word, I heard a yes, but also to understand, little grasp, understand it some, then we together look. 3PE anti-corrosion steel corrosion methods are generally used anti-corrosion coatings, anti-corrosion coating is uniformly dense coated on the surface of metal pipes by rust paint, cut it with a variety of corrosive media, is the most basic steel corrosion One approach. Pipe corrosion coating increasing use of composite materials or composite structure. These materials and structures to have good dielectric properties, physical properties, chemical stability and a wide temperature range and so on. 1, wall corrosion coating: pipe wall coating material types and conditions of use. ② wall corrosion coating: In order to prevent pipe corrosion, reduce friction and improve the transmission capacity and the inner surface of pipes coated film. Common amine-cured epoxy coatings, and polyamide resin, the coating having a thickness of 0.038 to 0.2 mm. To ensure a strong bond coating and the wall must be on the tube inner wall surface treatment. Since the 1970s tend to the inner tube, the outer wall of the same coating material selection, so that the tube inner and outer walls of the coating at the same time. ③ corrosion insulation coating: hot medium and small caliber in the output of crude oil or fuel oil pipeline, to the soil in order to reduce the heat pipe, the pipe insulation and corrosion plus external composite layer. Common insulation material is a rigid polyurethane foam, a temperature of -185 ~ 95 ℃. This material is soft texture, in order to improve its strength, plus insulating layer deposited on the outside layer of high-density polyethylene layer, forming a composite structure, in order to prevent infiltration of groundwater within the insulation. 2, such as the outer protective tube is polyethylene pipe, do not need anti-corrosion polyethylene odorless, non-toxic, feel like wax, has excellent low temperature performance (the lowest temperature up to -70 ~ -100 ℃), chemical stability Good resistance to most acid-base erosion (impatience with oxidation properties of acid), room temperature, soluble in common solvents, water absorption, but because it is a linear molecule can be slowly dissolved in certain organic solvents, not swell, excellent electrical insulation properties.
