Steel Pipe cleaning and maintenance need to follow certain methods to clean up. The main use of tools such as wire brush the surface of polished steel. Steel pipe cleaning and removal of loose or tilt can preheat the oxidation, rust, welding slag. Hand tools rust can reach Sa2 grade power tools rust up Sa3 level. If attached to a solid steel surface oxide scale, the result is not ideal tools rust, corrosion construction requirements not reach the depth of the anchor pattern.
Acid using solvent, emulsion cleaning fluid low pressure welded steel pipe surface, in order to achieve the removal of oil, grease, dust, lubricants and similar organisms, but it can not remove the steel surface rust, oxide, welding medicines, and therefore the production of anti-corrosion only as an adjunct. Different forms of ways and means to clear rust will cause some of the important impact of seamless, affecting a large number of performance and factors, in strict accordance with traditional Chinese medicine in cleaning certain principles and methods to clean up, to ensure that in use reflect a good value.
Generally two methods is used including chemical and electrolytic pickling process, pipeline corrosion using only chemical etching, to remove oxidation, rust, old coatings, sometimes used as a sand-blasting after reprocessing. Although chemical cleaning can achieve a certain surface cleanliness and roughness, but the anchor light pattern, and easy stacking of environmental pollution caused by spiral steel pipe. Rational used of means to clean up the rusty pipe fittings to ensure long time service in the production, create more production efficiency.
