Steel pipe anticorrosion refers to the surface of the steel pipe coated with a variety of anticorrosive materials to protect the steel pipe from environmental factors, to extend the service life of the steel pipe. There are many methods of steel pipe anticorrosion, the following is an introduction to several common methods of steel pipe anticorrosion.

Coating anti-corrosion

Coating anticorrosion is a coating on the surface of the steel pipe, forming a dense film, thus isolating the surface of the steel pipe and the surrounding environment to prevent corrosion of the steel pipe. The advantages of coating anticorrosion are simple construction, low cost, long life, the disadvantage is that the coating of wear resistance, impact resistance, resistance to bending and other performance requirements are high, otherwise it will affect the effect of anticorrosion. Commonly used coating anti-corrosion materials are epoxy resin, polyurethane, acrylate and so on.

Thermal spraying anti-corrosion

Thermal spraying anti-corrosion is the molten state of the spray material through the high-speed airflow sprayed on the surface of the steel pipe, forming a dense layer of coating, thus isolating the surface of the steel pipe and the surrounding environment, preventing corrosion of the steel pipe. The advantages of thermal spraying anti-corrosion are dense coating, strong adhesion, good anti-corrosion effect, the disadvantage is the construction difficulty, high cost, short life. Commonly used thermal spraying anti-corrosion materials are aluminum, zinc, stainless steel and so on.

The advantages of anti-corrosion plating are simple construction, low cost, good anti-corrosion effect, the disadvantage is that the thickness and uniformity of the plating layer requires high, otherwise it will affect the anti-corrosion effect. Commonly used plating anti-corrosion materials are chromium, zinc, tin, etc..

Corrosion inhibitor anti-corrosion

Corrosion inhibitor anti-corrosion is a corrosion inhibitor added to the surface of the steel pipe or the surrounding environment, thereby slowing down the corrosion rate of the steel pipe. The advantages of corrosion inhibitor anti-corrosion are simple construction, low cost, long life, the disadvantage is that the performance requirements of the corrosion inhibitor is higher, otherwise it will affect the anti-corrosion effect. Commonly used corrosion inhibitors are imidazoline, pickling corrosion inhibitors and so on.
