Why do stainless steel pipes get spots after cleaning?

Stainless steel pipe fittings are a small part of the big family of pipe fittings. It is called stainless steel pipe fittings because it is made of stainless steel as raw material. There are many members in it, including common elbows, tees, crosses, stainless steel reducers, etc., all of which belong to stainless steel pipe fittings. According to the connection method, we can divide stainless steel pipe fittings into four categories: connecting stainless steel pipe fittings, threaded stainless steel pipe fittings, welded stainless steel pipe fittings and flanged stainless steel pipe fittings. The main stainless steel materials used to make stainless steel p
