Stainless steel welded pipe production process:

Raw materials -- slaying -- welding pipe -- repairing end -- polishing -- inspection (printing) -- packaging -- shipment (warehousing) (decorative welded pipe).

Raw material - article points - welding pipe, heat treatment, correct, straightening, fix the end, pickling, water pressure test, inspection (spurts India) - packaging - shipment (transport) (tube) for piping weld pipe industry.

Chloride ions are found in salt, sweat, seawater, sea breezes, and soil. Stainless steel in the presence of chloride ions in the environment, corrosion is fast, even more than ordinary low carbon steel, chloride ions and alloying elements in the Fe formation complex, the Fe positive potential is reduced, and then by the oxidant to take electrons and be oxidized.

So there are requirements for the use of stainless steel environment, and the need to often wipe, remove dust, keep clean and dry.

316 and 317 stainless steels are molybdenum containing stainless steels. The molybdenum content in 317 stainless steel is slightly higher than that in 316 stainless steel. Because 316 stainless steel contains molybdenum, the overall performance of the steel is better than 310 and 304 stainless steel. Under high temperature conditions, when the concentration of sulfuric acid is lower than 15% and higher than 85%, 316 stainless steel has a wide range of uses. 316 stainless steel also has good resistance to chloride erosion, so it is usually used in Marine environments.
