In the oil and fuel pipeline anti-corrosion development process, LSAW metal pipe anti-corrosion area procedure is to decide the lifetime of one particular of the vital things, it is LSAW metal pipe anti-corrosion layer and irrespective of whether the mixture of a good premise.nThe analyze of qualified corporations, in addition to the lifetime of the coating depends on the variety of coating,Coating excellent and building of environmental elements, LSAW metal pipe coating area treatment of existence-span of about 50%, thus, ought to be strictly in accordance with normal coating the surface area of LSAW welded steel pipe requirements, continual advancement straight seam metal surface area treatment method system,LSAW steel pipe are predominantly the pursuing procedures in addition to embroidery classes:nn1, the use of solvent cleaning, emulsion cleaning the steel surface area, in buy to attain the removal of oil, grease, dust, lubricants
similar organisms, but it can not take out the steel floor rust, oxide, welding flux, etc., so the anti-federal government operations only as an adjunct.nntwo, pickling
nGenerally two strategies utilized to do chemical and electrolytic pickling approach, coating metal pipe using only chemical etching, to take away oxidation, rust, previous coatings, occasionally utilized as a sand-blasting right after reprocessing. Despite the fact that chemical cleansing can accomplish a specified area cleanliness and roughness, but the anchorpattern light, and straightforward to pollute the surrounding setting.nn3, equipment rust
nMainly use a wire brush and other resources on the polished metal area, can remove free oxide, rust, welding slag. Hand resources rust can get to Sa2 quality energy resources rust up Sa3 degree, if attached to a sound metal area oxide scale, equipment rust is not satisfactory,Attain the building prerequisites of corrosion depth of anchor pattern.n4, spray rust spray rust by large-electrical power large-speed rotating blade motor pushed spray, so that steel shot, grit, wire segments, minerals and other abrasive solid centrifugal power in the motor straight seam steel pipes underneath the floor of the spray treatment method, not only You can fully take out oxides, rust and dust and delicate steel pipe in severe abrasive effect and the purpose of friction, but also to realize the demanded uniform roughness.nnSpray rust, can not only broaden the role of bodily adsorption tube surface, and can enhance the corrosion layer and the mechanical adhesion of the tube surface area. Thus, the jet rust is the great way to pipe corrosion. Usually, shot peening rust inside the tube is mostly utilised for floor treatment, shot blasting straight seam metal pipes largely made use of for the outer area treatment method.stringent requirements of the output method to be rust-connected complex technical specs, to avoid operational mistakes consequence in straight seam steel pipe to 2nd injuries, in addition to straight seam metal pipes as a result of embroidery, embroidered products visual appeal and in addition it will be far more easy than before, than straight seam metal pipes embroidered in the metal market is a usually utilized technique.
