I still remember the time when I was a factory maintenance worker. Some of the raw materials produced by the factory were quite corrosive. At first, some steel pipes coated with anti-corrosive materials were used. Of course, compared with ordinary transport pipelines, the treated ones are much better. However, the effect is only temporary. In real life, plastics like polyethylene can play a role in corrosion prevention and are relatively affordable.
Valves should be considered as part of the easily corroded areas. Some rotating parts, after being eroded by corrosive substances, tend to stick together easily. As a senior pipeline repair worker, I am quite familiar with these issues. They may need to be replaced almost once a month, which is not only troublesome for us but also has a certain impact on profits.
