Dear experts on this forum, I have some questions regarding valve materials
Thread Content
As is well known, many valves used in China are selected or designed in accordance with the American ASTM standards. Therefore, I have a question regarding valve materials: could you please provide detailed examples of the commonly used valve materials specified in ASTM standards for power plants, such as A105, A219-WCA/B/C, A355-F91, etc., as well as those specified in ASTM standards for the petrochemical industry? Including their pressure-temperature relationship? Could someone explain the relationship between temperature and corrosion resistance, etc.?
For something that one can research on their own and take notes about, it’s better to do it oneself; otherwise, not only does one fail to go through the process of learning and accumulation, but it also wastes time for others as well
Where can I check it? What I find online isn’t necessarily accurate
