Cleaning of seamless elbows Abrasion-resistant elbows should be cleaned with solvents and emulsions. Ceramic elbow, ceramic composite elbow surface, in order to achieve the purpose of removing oil, grease, dust, smoothing agent and similar organic matter, but it cannot remove rust, oxide scale, flux, etc. on the steel surface, so it is only used for anti-corrosion consumption wrist Belt auxiliary material.

The rust removal of seamless elbows is mainly to use wire brushes and other tools to stop the grinding of the steel surface, which can remove loose or warped oxide scale, rust, welding slag, etc. The rust removal with hand tools can reach Sa2 level, and the rust removal with electric tools can reach Sa3 level. If the steel surface adheres to solid oxygen

If the steel surface adheres to the solid scale, the rust removal of the tool will not be affected and the depth of the anchor pattern required for corrosion resistant construction will not be achieved.
Pickling of seamless elbows Generally, two methods, chemical and electrolytic, are used for pickling. Wear-resistant elbows, wear-resistant ceramic elbows, ceramic elbows, ceramic composite elbows are only used for corrosion protection, to remove scale, rust and old coatings, and sometimes used as reprocessing after sandblasting and rust removal. Although chemical cleaning can achieve a certain level of cleanliness and roughness, it has a shallow settling line and is prone to contamination of the environment.
The application of seamless elbows is now very common in people's lives. Do you know what grades seamless elbows are divided into? The surface of ordinary hot-rolled seamless elbow products is FA after pickling, and the seamless elbow products are FB cold-rolled seamless elbow products. The surface requirements of ordinary seamless elbow products are not high, such as the use of inner car panels FB surface. For the outer panels of some ordinary cars that are not particularly harsh, use the FD surface of the FC car.
