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 organic matter, but it cannot remove rust, scale, welding flux, etc. on the steel surface. Therefore, it is only used as an auxiliary method in antiseptic production.

Generally, chemical and electrolytic methods are used for pickling treatment. Pipeline anti-corrosion only uses chemical pickling, which can remove oxide scale, rust, and old coatings. Sometimes it can be used as reprocessing after sandblasting and rust removal. Although chemical cleaning can make the surface cleanliness and roughness, its anchor lines are shallow, and it is easy to cause pollution to the stacking environment of SSAW steel pipe.

When using reasonable methods to sort out the rusty pipe and pipe fittings, ensure that them will serve the production for a long time, and invent more production benefits.
