API-5L Q345 Spiral Welded Pipe



Spiral pipe is mainly used for oil and natural gas pipeline, its specification is expressed by outer diameter * wall thickness.Spiral pipe has one side welding and two sides welding, welding pipe should ensure the water pressure test, weld tensile strength and cold bending performance in accordance with the provisions.


Surface treatment:


1, cleanSolvent,


 emulsion cleaning steel surface, in order to reach the removal of oil, grease, dust, smooth agent and similar organic matter, but it can not remove steel surface rust, scale, flux, etc.


2. Rust removal of tools


First use steel wire brush and other tools to polish the appearance of steel, can remove loose or warped oxide, rust, welding slag and so on.Manual tool derusting can reach Sa2 level, power tool derusting can reach Sa3 level, if the steel surface adheres to a strong scale, tool derusting results are not ideal, not up to the anti-corrosion construction requirements of anchor depth.


3, pickling


Common chemical and electrolytic pickling treatment, pipeline corrosion only using chemical pickling, can remove the scale, rust, old coating, sometimes used as sand blasting after the treatment of rust.Chemical cleaning is able to make the appearance of inevitable cleanliness and roughness, but its shallow anchorage, and easy to form a pollution of the situation.


4. Spray (toss) jet derusting


Spray shot derusting (cast) is a high power motor drive spray (cast) blade high-speed twist, make steel shot, steel grit, wire section, minerals and other abrasive under the centrifugal force effect on steel tube appearance spray (cast) disposal, not only can completely eliminate rust, oxides and dirt, and the effect of steel tube in the fierce impact and friction abrasive, can reach the requirements of coarse degree on average.After spraying (throwing), 


the physical adsorption effect on the surface of the pipe can be expanded, and the mechanical adhesion effect between the anti-corrosion layer and the surface of the pipe can be enhanced.Therefore, spraying (throwing) jet derusting is the ideal derusting method for pipeline anticorrosion.Generally speaking, shot peening (sand) derusting is primarily used for pipe internal surface treatment, and shot blasting (sand) derusting is primarily used for pipe surface treatment.
