1. The common method of external anticorrosion of steel pipes: using cathodic protection alone is not economical due to too much power consumption. Therefore, the combined protection of the anti-corrosion layer and cathodic protection, the cathodic protection that will be concentrated on the exposed metal surface at the defects of the anti-corrosion layer, etc., is the most economical protection form. “Combined protection” is a protection method “mainly based on anti-corrosion layer and supplemented by cathodic protection”.
2. Anti-corrosion treatment inside the steel pipeline: main anti-corrosion measures: anti-corrosion layer and cathodic protection. The anti-corrosion layer mainly plays an isolation role in metal corrosion control. The metal exposed at the defect and the part covered by the anti-corrosion layer form a localized corrosion cell with a small anode and a large cathode, which will accelerate the corrosion rate of the exposed metal. Therefore, the effect of using anti-corrosion layer protection alone is not ideal. Prepare the tools needed for steel pipeline corrosion and protection and the basic introductory course of external anticorrosion measures for steel pipelines.
3. External anti-corrosion materials for steel pipes: The external anti-corrosion measures for metal pipes will be beneficial. Polyethylene and polypropylene tapes to assess the corrosion status of steel pipelines and the safety risks of steel pipeline operations.
4. Steel pipeline anti-corrosion treatment: A set of proprietary external anti-corrosion layer detection technology has been summed up by combining various detection methods, which can use advanced instruments and technologies to detect the external anti-corrosion layer without excavation and without affecting the normal operation of the steel pipeline. Conduct comprehensive and systematic detection of defects on the steel pipeline body, accurately locate the damaged point, evaluate the risk, integrity, and operation status of the steel pipeline, analyze the cause of steel pipeline corrosion and put forward repair suggestions, timely repair the damaged anti-corrosion layer of the steel pipeline, and aim at local corrosion. Steel pipeline maintenance and repairs to extend steel pipeline life.
