We all know that stainless steel seamless steel pipes generally undergo some special treatments when they leave the factory to make the surface look bright and there will be no rust, but when we use it for a long time, coupled with environmental and other factors, There will still be some rust, so how do we clean the rust of stainless steel seamless steel pipes?

After the production of stainless steel seamless pipes, a procedure is generally carried out, that is, "pickling", which can remove surface pollution and stains for stainless steel pipes. The surface of the stainless steel seamless pipe is acid white after the production is completed.

The preparations to be done before acid cleaning the surface of stainless steel seamless pipes include pickling and passivation. The welding coating, splashes, burrs, and dirt on the pipe fitting surface must be cleaned up before passivation. The surface of the stainless steel pipe should be wiped clean with gasoline or other organic solvents. If it is a large area of dirt, it can be cleaned with steam or 3~5% NaOH solution, and then rinsed with clean water and allowed to dry. Note that the CL -concentration of the clean water used should not exceed 25mg/l.

What should I do when there is a little rust on the surface of the stainless steel seamless pipe or other dirty things that are difficult to wash off? You can consider using an acid process to clean the slight rust on the surface of the stainless steel thick-walled pipe without damaging the layer on the surface of the stainless steel pipe Oxide film or other substrates of stainless steel pipes, the dirt on the surface of the stainless steel seamless pipe will also disappear so that the surface of the stainless steel pipe can be purified.
