1. Use solvents and emulsions to clean the surface of anti-corrosion spiral steel pipes. This can remove organic matter on the surface of spiral steel pipes, but it cannot remove surface rust, oxide scale, flux, etc., so cleaning can only be used as an auxiliary means.2. Use wire brushes, sandpaper,
