3YC-7,3YC-8,3YC-18,3YC-21,3YC-22和6YC-2合金是我所近年来研制成功的在不同腐蚀介质中具有良好性能的耐腐蚀仪表材料。近二年来曾由天津仪表厂,大连仪表厂,四川仪表七厂,四川仪表十一厂及天府仪表厂(原名为彭县仪表厂)等24个厂家用于制作防腐仪表(变送器,调节伐,压力表及流量计等),在天然气田,化工厂及冶炼厂等20几家工厂使用,取得良好的效果。 3YC-7,3YC-8,3YC-22和6YC-2合金是特为天然气输运工程而研制的抗硫仪表材料,适合于制做低、中压压力表弹簧管,差压和压力变送器膜片、膜盒、流量计的轴承、滚珠等敏感元件或构件,在天然气田中使用寿命已达5年以上。3YC-18和3YC-21合金是为解
3YC-7, 3YC-8, 3YC-18, 3YC-21, 3YC-22 and 6YC-2 alloys are corrosion resistant instrumentation materials that have been successfully developed in recent years and have good performance in different corrosive media. In the past two years, 24 manufacturers such as Tianjin Instrument Factory, Dalian Instrument Factory, Sichuan Instrument Seven Factory, Sichuan Instrument 11 Factory and Tianfu Instrument Factory (formerly Peng County Instrument Factory) were used to make anti-corrosion instruments Cutting, pressure gauges and flow meters, etc.) and achieved good results in 20 plants in natural gas fields, chemical plants and smelters. 3YC-7, 3YC-8, 3YC-22 and 6YC-2 alloys are sulfur-free instrumentation materials specially developed for natural gas transportation projects. They are suitable for producing low and medium pressure pressure gauge spring tubes, differential pressure and pressure transmission Diaphragm, diaphragm, flow meter bearings, ball bearings and other sensitive components or components, the service life of natural gas fields has reached more than 5 years. 3YC-18 and 3YC-21 alloy is solution
