Anti-corrosion treatment methods for steel pipes and pipelines

The anti-corrosion specifications for steel pipes mainly depend on the anti-corrosion materials you choose. Such as buried pipeline polyethylene anti-corrosion SY/T0414-98 0413-02, etc. With the continuous development of our country's economy, the country is vigorously developing the energy industry. Long-distance oil and gas pipelines are an important way to ensure energy security. During the anti-corrosion construction process of oil (gas) pipelines, the surface treatment of steel pipes is one of the key factors that determine the service life of the anti-corrosion pipelines. First, it is the prerequisite for whether the anti-corrosion layer and the steel pipe can be firmly combined. It has been verified by research institutions that, in addition to factors such as coating type, coating quality, and construction environment, the surface treatment of steel pipes accounts for about 50% of the impact on the life of the anti-corrosion layer. Therefore, the anti-corrosion layer specifications should be strictly followed. The requirements for the surface of steel pipes are constantly explored and summarized, and the surface treatment methods of steel pipes are constantly improved.
