The way to remove the corrosion of GBT 8162 42CrMo seamless steel pipe

GBT 8162 42CrMo seamless steel pipe can be supplied by katalor with good price and quality. Katalor is experience on supplying GBT 8162 42CrMo seamless steel pipe. The bellow is The way to remove the corrosion of GBT 8162 42CrMo seamless steel pipe.

1. Tool rust removal
GBT 8162 42CrMo seamless pipe surface is polished with steel brushes and other tools to remove loose or sloping scale, rust and slag. The manual tool can remove rust up to Sa2 level, and the power tool can remove rust up to Sa3 level. If the surface of the 42CrMo seamless pipe is attached to the solid scale, the rust removal effect of the tool is not ideal, and the anti-corrosion construction requirement of the anchor depth cannot be achieved.

2. Remove the corrosion of GBT 8162 42CrMo seamless steel pipe
Solvents and emulsions are used to clean the surface of GBT 8162 42CrMo seamless tubes and remove oil, grease, dust, lubricants and similar organics. This method can not remove the corrosion, scale and flux of the surface of the 42CrMo seamless pipe, so it is only an auxiliary means in the anti-corrosion production.
3. Sandblasting and rust removal GBT 8162 42CrMo seamless steel pipe
Sand blasting not only completely removes the surface rust, oxides and dirt of GBT 8162 42CrMo seamless steel tube, but also achieves uniform roughness under abrasive impact and frictio

4. Pickling removes corrosion of GBT 8162 42CrMo seamless steel pipe
Typically, two chemical and electrolytic methods are used for pickling. Only chemical pickling is used in pipeline anti-corrosion to remove scale, rust and old coatings. Sometimes it can be used for reprocessing after sand blasting. Although the chemical cleaning can make the surface of GBT 8162 42CrMo seamless steel pipe reach a certain degree of cleanliness and roughness, its anchor pattern is shallow and it is easy to pollute the environment.

One of the most important problems encountered when using GBT 8162 42CrMo seamless tubes is the rust problem. Once rusted, many of the features of the 42CrMo seamless tube are not working. Therefore, we need to prevent the 42CrMo steel pipe from rusting and master some methods of descaling. Katalor hope the information can help you.
