Roughness effects of coated steel pipe coating layer
Steel pipe surface treatment is a key factors to determine pipeline life, it is the ability to securely and steel pipe coating combined premise verified by research institutions, in addition to the life of the coating depends on the type of coating, coating quality and construction environment and other factors, steel pipe coating surface treatment on the life of about 50%, therefore, it should be strictly in accordance with the specification for the steel surface coating requirements, and continuously explore and summarize the continuous improvement of steel surface treatment method.
