Surface cleaning method of Seamless pipe

Surface cleaning method of seamless steel pipe: cleaning,Seamless pipe using solvents and emulsions to clean the steel surface to remove oil, grease, dust,Seamless pipe lubricants (function: can reduce or avoid friction and wear) and similar organic matter, but it cannot remove the surface of the steel Rust, oxide scale, welding powder, etc.so they are only used as auxiliary means in anti-corrosion production. Tool rust removal,Seamless pipe mainly using tools such as wire brushes to polish the steel surface, which can remove loose or warped oxide scale, rust, welding slag,Seamless pipe etc. The rust removal of hand tools can reach Sa2 level, and the rust removal of power tools can reach Sa3 level. If the steel surface is adhered with solid oxide scale, the tool rust removal effect is not ideal,Seamless pipe and the anchor pattern depth required for anti-corrosion construction cannot be reached.

Pickling: Generally, two methods of chemical and electrolysis are used for pickling. Only chemical pickling is used for pipeline anticorrosion, which can remove oxide scale, rust,Seamless pipe and old coatings. Sometimes it can be used as a reprocessing after sandblasting and rust removal. Although chemical cleaning can achieve a certain degree of cleanliness and roughness on the surface, its anchor lines are shallow and easily pollute the environment.

Spray (throwing) rust removal: spray (throwing) rust removal is driven by a high-power motor to drive the spray (throwing) blades to rotate at a high speed, so that the steel grit,Seamless pipe steel shot, iron wire section, minerals and other abrasives will act on the centrifugal force (role) Spraying (projecting) the surface of the steel pipe can not only completely remove rust, oxide and dirt, but the steel pipe can achieve the required uniform roughness under the action of the violent impact and friction of the abrasive. Boiler tubes can be used for pipelines,Seamless pipe thermal equipment, machinery industry,Seamless pipe petroleum geological exploration, containers, chemical industry and special purposes. It is a kind of seamless tube. The manufacturing method is the same as that of seamless pipes, but there are strict requirements on the steel grades used in the manufacture of steel pipes. According to the operating temperature,Seamless pipe it can be divided into general boiler tubes and high-pressure boiler tubes.
