During the production of stainless steel ball valves, it is easy to touch other metal iron products, so it is easy to rust, so how can we avoid rust as much as possible?
(1) After the rough product is finished and pickled, it must be rinsed. If there are sand holes or perforations on the surface, use argon arc welding to weld it with gas protection, and then polish it and perform solution heat treatment.
(2) After the finished product, processing and pressure test are completed, it should be washed with water added with anti-rust powder.
(3) When transporting stainless steel ball valves, they should be packed in wooden boxes as much as possible to prevent contact with other metal products.
(4) After the pipeline installation is completed, it should be maintained regularly. The specific operations are as follows: ①Apply lubricating oil to the valve stem frequently. ② Open and close the valve several times to make the inside ball, valve stem and sealing surface different.
These methods can help stainless steel ball valves to avoid rust as much as possible and prolong their service life.
