304 Stainless Steel Welded Pipe Plate Cleaning Requirements

1. For 304 stainless steel welded pipe sheets, the lower the surface roughness, the smoother the surface, the harder it is for foreign matter to attach, and the lower the chance of local corrosion of each part. Therefore, stainless steel plates should have as finely machined surfaces as possible.
2. The surface cleanliness of the 304 stainless steel welded pipe sheet is very important. Cleaning should be carried out carefully after passivation, because the residual acid promotes the cathode reaction and ruptures the film layer, thereby activating the stainless steel plate and drastically reducing the corrosion resistance.
3. The passivation film of 304 stainless steel welded pipe sheet is a thermodynamically suppressed metastable structure, and its protective efficiency is related to the environmental medium. It should be cleaned regularly during use to remove harmful substances that have been attached to the surface for a long time.
