Antiseptic Treatment of SSAW Steel Pipe
The individual quality of SSAW steel pipe is large, it should be stacked outdoors, but this will inevitably be exposed to the sun and rain, so the problem of rust has always plagued the storage time and conditions of the SSAW steel pipe. Therefore, it is necessary for us to know the rust prevention of SSAW steel pipe. The first thing is to use steel wire brushes or other things to polish the surface of the steel pipes. The cleaning and preheating of the SSAW steel pipe can remove loose or lifted scale, rust, welding slag and so on. Manual rust removal can reach Sa2 level, and power rust removal can reach Sa3 level. If the steel surface is firmly attached to the iron oxide skin and the rust removal effect is not large, the anchor depth required for anti-corrosion construction cannot be achieved. Pickling uses solvents and emulsions to clean the appearance of SSAW steel pipe for low-pressure fluid transportation to remove oil, grease, dust, lubricants and similar orga...
