Steel pipe anti-corrosion

Steel pipe anti-corrosion

Steel pipe anti-corrosion is a series of measures taken to prevent steel pipes from being corroded during use. If steel pipes are not treated with anti-corrosion, they are prone to corrosion. Corrosion will make the wall thickness of steel pipes thinner, reduce their strength and bearing capacity, and may cause problems such as rupture and leakage during use of steel pipes, affecting their normal use functions. For example, in pipelines that transport media such as oil and gas, once the steel pipe is corroded and perforated, it will not only cause medium leakage, but also may cause safety accidents and environmental pollution.

Coating anti-corrosion

Use coating to form a protective film on the surface of the steel pipe to prevent the corrosive medium from contacting the steel pipe. Commonly used coatings include epoxy coatings, polyurethane coatings, etc. This method is easy to construct and relatively low in cost, and is suitable for steel pipe anti-corrosion under various environmental conditions. Cathode protection By applying cathodic current to the steel pipe, the steel pipe becomes the cathode, thereby inhibiting the occurrence of corrosion. Cathode protection is usually used in combination with coating anti-corrosion, which can effectively improve the anti-corrosion performance of the steel pipe. Corrosion inhibitor anti-corrosion Add corrosion inhibitors to the transported medium to slow down the corrosion rate of the steel pipe. The selection of corrosion inhibitors needs to be based on the properties of the transported medium and the conditions of use.
