The anti-corrosion method of good price and quality Anti-corrosion pipeline is generally to use coating anti-corrosion. Let's learn about the knowledge of coating anti-corrosion.

Coating anti-corrosion is to apply paint evenly and densely on the surface of the derusted metal pipeline to isolate it from various corrosive media. It is one of the most basic methods of good price and quality Anti-corrosion pipeline. Anti-corrosion coatings for good price and quality Anti-corrosion pipelines are increasingly made of composite materials or composite structures. These materials and structures should have good dielectric properties, physical properties, stable chemical properties and a wide temperature range.

1. Outer wall anti-corrosion coating
Good price and quality Anti-corrosion pipeline outer wall coating material types and conditions of use.

2. Inner wall anti-corrosion coating
In order to prevent corrosion in the good price and quality Anti-corrosion pipeline, reduce frictional resistance, and increase the transmission capacity, the film is applied to the inner wall of the pipe. Commonly used coatings are amine-cured epoxy resin and polyamide epoxy resin, and the coating thickness is 0.038 to 0.2 mm. In order to ensure that the coating is firmly bonded to the pipe wall, the inner wall of the pipe must be surface treated. Since the 1970s, the same material has been used for the coating of the inner and outer walls of the tube, so that the coating of the inner and outer walls of the tube can be carried out at the same time.

3. Anti-corrosion and thermal insulation coating
In order to reduce the heat dissipation of the pipeline to the soil on the medium and small diameter heat transfer crude oil or fuel oil pipeline, a composite layer of heat preservation and anticorrosion is added to the outside of the good price and quality Anti-corrosion pipeline. The commonly used thermal insulation material is rigid polyurethane foam, and the applicable temperature is -185 to 95 °C. This material is soft in texture. In order to improve its strength, a layer of high-density polyethylene is applied outside the insulation layer to form a composite material structure to prevent groundwater from seeping into the insulation layer.

4. Other situations
For example, the good price and quality Anti-corrosion pipeline is a polyethylene pipe, so there is no need to do anti-corrosion. Polyethylene is odorless, non-toxic, feels like wax, has excellent low temperature resistance (the lowest operating temperature can reach -70 ~ -100 ℃), good chemical stability, and can resist the erosion of most acids and alkalis (not resistant to oxidation It is insoluble in common solvents at room temperature and has low water absorption, but because it is a linear molecule, it can slowly dissolve in some organic solvents without swelling, and has excellent electrical insulation properties.
