5. Can we visit your factory?
--Warmly welcome. Once we have your schedule, we will arrange the professional sales team to follow up your case.
6.What are the advantages and disadvantages of the stainless steel welded pipe and the polished welded pipe?
--First, the wall thickness of stainless steel welded pipe with weld acid pickling is more uniform and the pressure bearing performance is stronger. The wall thickness of the original pipe will be thinner, especially in the weld area, when the polishing pipe is artificially polished. The thinner the wall thickness of the weld zone, the lower its bearing capacity.
Secondly, stainless steel welded pipe with welded seam pickling can ensure the integrity of austenitic stainless steel. Most stainless steel welded pipes are made of austenitic stainless steel as raw materials, such as 201, 202, 304 and 316 stainless steel, because the austenitic microstructure is not magnetic or weak magnetic. After polishing, the polishing pipe will result in small change in chemical composition, which makes the austenitic stainless steel have more obvious magnetism.
