On the importance of equipment maintenance
Thread Content
In our chemical production processes, it is necessary to frequently open and close valves, tighten or loosen bolts, as well as carry out equipment maintenance. In practical work, it is inevitable to encounter issues such as bolt rust and stuck valves, which **adds a lot of unnecessary workload to us. This also highlights the importance of regular maintenance of valves, bolts, and equipment. The most commonly used method is still \"applying butter,\" and it is practical, convenient, and cost-effective for both bolts and valve stems. However, for valve stems that do not need to be opened or closed for extended periods of time, evaporation and drying make it even more difficult to operate them; therefore, it is necessary to use \"casing\" or \"film coating\" as a form of maintenance. Although taking care of the valve bolts is simple, it involves many detailed tasks, and if proper attention is not paid, it can lead to problems down the road! The original poster lacks experience; please, colleagues from all walks of life, keep adding to it!
Agreed, agreed; the factory generally applies butter
This is quite telling: there was a DN1400 butterfly valve that wasn’t used for a whole year, and even after bending the valve stem, it still wouldn’t open.
We once had a DN200 valve that required three people to operate it slowly; regular maintenance is really important
