Do you know how the degreasing treatment of stainless steel ball valves is carried out? The following is an introduction to the degreasing treatment methods and inspection requirements for stainless steel ball valves.
①According to the requirements of processing, some parts need to be polished, and there should be no processing burrs on the surface.
②All parts should be degreased.
③The stainless steel ball valve should be pickled and passivated after degreasing (Note: The cleaning agent does not contain phosphorus).
④ After the stainless steel ball valve is pickled and passivated, it should be rinsed with pure water, and there should be no chemical residue.
⑤ Parts should be dried with non-woven cloth, or blown dry with clean nitrogen, and there should be no wire wool left on the surface of the parts.
⑥Use non-woven fabric or precision filter paper dipped in analytical pure alcohol to wipe the parts one by one until the surface is free of dirt.
The degreasing treatment of stainless steel ball valves should pay attention to these aspects.
