Recently, the General Machinery Industry Association of China organized a product appraisal meeting in Tianjin for the development of domestically developed cryogenic ball valves and cryogenic butterfly valves for key valves for LNG.
The LNG cryogenic valve products identified in this appraisal meeting are: NPS10 CL1500 cryogenic ball valve and NPS 24 CL150 cryogenic butterfly valve. Experts in the appraisal group agreed that the “localization of key equipment of natural gas liquefaction equipment”—the development of NPS10CL1500 cryogenic ball valves and NPS24 CL150 cryogenic butterfly valve prototypes for LNG key valves have filled the domestic gap, and the products have independent Intellectual property rights, main technical parameters and performance indicators have reached the advanced level of similar foreign products, which can be promoted and applied in ultra-low temperature fields such as liquefied natural gas.
As the key casting manufacturer of this appraisal product-SCHR Precision Machinery Manufacturing Co., Ltd. supplied NPS10 CL1500 stainless steel ultra-low temperature ball valve body and bonnet; NPS24 CL150 stainless steel ultra-low temperature valve body, both of which are CF8M/CF3M double certificate products. After SCHR received the demand to provide domestic castings last year, it organized relevant personnel to go all out in less than 2 months: process design-simulation casting-model manufacturing-product production-radiographic inspection-finished product delivery and other work and product machinery The performance and chemical composition meet the material technical requirements of the valve's ultra-low temperature working condition at one time.
SCHR has been committed to providing various types of high-quality cast steel for domestic and foreign valve manufacturers, and is the first qualified supplier of valve parts castings for Sinopec. As the country promotes the localization and localization of key "bottleneck" technologies and components, SCHR looks forward to participating in more key valve localization projects, helping to solve the "bottleneck" key forged parts, and serving the localized high-end supply chain.
