Surface treatment of ERW steel pipe

With the sustainable development of economy in our country, the country to vigorously develop the energy industry, long distance oil and gas pipeline is an important means of energy security, in the process of oil (gas) pipeline anticorrosion construction, steel tube surface treatment is one of the key factors determine the service life of the pipeline corrosion, it is a solid combination of anti-corrosion layer and steel tube can be provided. Verified by research institutions and the life of the coating depends on the quality of coating types, coating and environmental factors such as construction, steel tube surface treatment effects on coating life accounted for about 50%, therefore, should be in strict accordance with the specification on the coating on the surface of steel pipe requirements, continuously explore and summary, continuously improve steel pipe surface treatment.
