Do you know the surface treatment methods for LSAW steel pipes?

Nowadays, LSAW steel pipes are being used more and more frequently in our daily lives. Do you know the surface treatment methods of straight seam steel pipes? Below, please follow the editor of straight seam steel pipes to learn more.

1. The cleaning of LSAW steel pipes uses solvents and emulsions to clean the steel surface to remove oil, grease, dust, lubricants, and similar organic substances. However, it cannot remove oxide skin, rust on the steel surface, welding flux, etc., and can only be used as an auxiliary means for anti-corrosion production.

2. If the steel surface is firmly attached to the iron oxide scale, its rust removal effect is not ideal and cannot meet the requirements for anchoring particle depth in anti-corrosion construction. The rust removal tools for straight seam steel pipes mainly use tools such as wire brushes to polish the steel surface. Manual rust removal can reach SA2 level, while power tool rust removal can reach SA3 level, which can remove loose, or protruding oxide scale, rust, welding slag, etc.

3. The acid cleaning of LSAW steel pipes generally adopts chemical and electrolytic methods for treatment, which can be used as a pre-treatment after sandblasting and rust removal. Although chemical cleaning can achieve a certain degree of cleanliness and roughness on the surface, its anchoring particles are shallow and easy to cause pollution to the environment. Chemical acid cleaning can only be used for pipeline anti-corrosion, which can remove scale, rust, and old coatings.
