Steel pipe factory supplier introduces to you three methods of ASTM A334 Seamless Carbon Steel Pipes for Low Temperature Use rust removal.
(1)Clean and remove rust
Cleaning and rust removal do not use ordinary water, but use chemicals to remove rust on the surface of ASTM A334 steel pipes, dissolve and peel off the rust, and achieve the effect of rust removal. But this method can only play a supporting role.
2. Pickling and rust removal
Pickling and rust removal is a commonly used method at present. Pickling and rust removal are carried out through two methods, chemical and electrolysis, which can remove oxide scale and rust stains and make the surface of the ASTM A334 steel pipe reach good cleanliness and roughness. However, It will cause pollution to the environment and needs to be improved.
3. Mechanical rust removal
Mechanical rust removal uses mechanical tools to remove rust from ASTM A334 steel pipes. Currently, the most commonly used method is to rub the surface of the steel pipe with a rust-removing wire brush to achieve the effect of rust removal. It can remove oxide scale, welding slag and rust on the surface of steel pipes, and it is one of several rust removal methods currently available.
