Main application fields of forged steel valvesIssuing time:2019-07-12 00:00Link:http://www.suntti.com.cn What are the main application areas of forged steel valves? Sandi Valve Industry helps you introduce: 1. Valves for Petroleum Installations (1) Refining unit. Most of the valves used in oil refining units are pipeline valves, mainly gate valves, globe valves, check valves, safety valves, ball valves, butterfly valves, traps, among which the demand for gate valves accounts for about 80% of the total number of valves (valves account for 3% to 5% of the total investment in the device); (2) Chemical fiber plant. Chemical fiber products mainly include polyester, acrylic and vinylon. The ball valve and jacket valve (jacket ball valve, jacket gate valve and jacket cut-off valve) of the valve are needed. (3) Propylene clearing unit. In general, the device needs scale production valves, mainly gate valves, globe valves, check valves, ball valves, traps, needle-shaped globe valves, cock valves, of which the gate valves account for about 75% of the total number of valves. (4) Ammonia plant. Because of the different methods of ammonia synthesis and purification, the process flow is different, and the technical functions of the valves required are also different. At present, domestic ammonia plants mainly need gate valves, globe valves, check valves, traps, butterfly valves, ball valves, diaphragm valves, control valves, needle valves, safety valves, high temperature and low temperature valves. |
