GF industrial pipe cleaning uses solvents and emulsifiers to clean steel surface to remove oil, grease, dust, lubricants and similar organic matter, but it can not remove rust, oxide scale, welding flux on steel surface, so it is only used as an auxiliary means in anti-corrosion production.
1. Solvents and emulsifiers are used to clean steel surface in order to remove oil, grease, dust, lubricants and similar organic substances. However, they can not remove rust, oxide scale and welding flux on steel surface, so they are only used as auxiliary means in anti-corrosion production. The treatment method of manual anti-corrosion steel pipe for spiral steel pipe can reach Sa2 level, and the rust removal of power tools can reach Sa3 level. If the steel surface is adhered to a solid oxide scale, the effect of tool rust removal is not ideal, and the depth of anchor lines required for anti-corrosion construction can not be reached.
