Concrete operation method for surface treatment of steel surface treatment and erw technique steel pipe

Concrete operation method for surface treatment of steel tube. We know that steel pipe surface treatment is one of the key factors determine the service life of the pipeline corrosion, it is a precondition for whether the anti-corrosion layer and steel tube can be combined. It is verified by the research institutions that the life of the coating depends on the quality of coating types, coating surface treatment and erw technique steel pipeCorrosion Resistance Treatment of Seamless Steel Pipe SurfaceIn order to improve the seamless steel pipes for oil transportation, usually the surface should be treated for corrosion resistance. Common treatments include cleaning, descaling, pickling, shot blasting four methods. 1. Cleaning. The grease, dust, lubricants, organic matter on the surface of seamless steel pipes usually can be cleaned by solvent or emulsion.Difference between Seamless & ERW Stainless Steel pipeCommon sizes for ERW Steel Pipe range from 2 3 8 inch OD to 24 inch OD in a variety of lengths to over 100 feet. Surface finishes are available in bare and coated formats and processing can be handled on site to customer specifications. What Technologies are used to manufacture Seamless & ERW Pipes?
