How much do you know about the maintenance of stainless steel ball valves? The maintenance of stainless steel ball valves is very important. Stainless steel ball valves are easy to touch with other metal iron products during production, which will increase the probability of rusting. If the maintenance is not done well, it will affect a series of problems such as subsequent use, and may also cause the valve to rust. So how to maintain the stainless steel ball valve?
1. After the rough is finished, it has been pickled and must be rinsed. If sand holes or perforations are found, use argon arc welding to weld them with gas protection, and then perform grinding and solution treatment.
2. Finished products, after processing and pressure testing, should be rinsed with water added with anti-rust powder.
3. It is best to pack the stainless steel ball valve in a wooden box during transportation so that it does not come into contact with metal products.
4. After the pipeline is installed, it should be maintained regularly, for example, lubricating oil is often applied to the valve stem.
5. The valve should be opened and closed several times properly, so that the inner ball, valve stem and sealing surface are not easy to assimilate.
Stainless steel ball valves are now widely used, mainly for cutting, distributing and changing the flow direction of media.
