Standard Cleaning Procedures for Seamless Steel Pipes

1. Seamless steel tube cleaning

Utilizing solvents and emulsions to clean the surfaces of abrasion-resistant pipes, ceramic tubes, and ceramic composite pipes for the removal of oil, grease, dust, lubricants, and similar organic substances. However, it does not remove rust, scale, or flux from steel surfaces, thus serving only as an auxiliary method in anti-corrosion production.

2. Seamless Steel Pipe Tool Descaling

Steel surfaces are primarily polished using tools such as wire brushes to remove loose or raised oxide scales, rust, and weld slag. Manual tool rust removal can achieve a Sa2 level, while power tool rust removal can reach a Sa3 level. However, if the steel surface has firmly attached oxide scales, the tool's rust removal effect is not ideal and does not meet the anchor depth requirements for anti-corrosion construction.

3. Pickling of Seamless Steel Tubes

Chemical and electrolytic methods are typically used for pickling processes, while wear-resistant pipes, ceramic pipes, and composite ceramic pipes are only coated with chemical pickling to remove oxidation scale, rust, and old coatings. Sometimes, it can also be used as a secondary treatment after sandblasting. Although chemical cleaning can achieve a certain level of cleanliness and roughness on the surface, it has shallow anchor patterns and is prone to environmental pollution.
