Anti-rust method of stainless steel flange ball valve

We know that the stainless steel flanged ball valve is a valve with excellent performance, which basically does not rust during daily use. However, this is not absolute. If you don't pay attention, there will still be rust during its use. How to prevent this?
Stainless steel flanged ball valves are very easy to contact with other metal iron products during the manufacturing process. If the finished product is mixed with other metals, it may rust in the process of future use. In order to keep it from rusting all the time, the easiest way is to follow the process below:
1. After the rough product is finished, it must be cleaned after pickling. If there are sand holes or perforations, it should be gas shielded by argon arc welding. Then grind again, and then carry out solid melting treatment;
2. The finished product should be rinsed with water with anti-rust powder added after the processing and pressure test is completed. 3. Use wooden boxes as much as possible during transportation and do not touch metal products.
4. After the pipeline is installed, it should be regularly maintained and maintained. For example, the valve stem should be lubricated frequently, and the valve should be opened and closed several times properly, so that the valve stem and the sealing surface are not easy to assimilate.
Doing the above points can protect the stainless steel flanged ball valve from rusting.
