Another key equipment has achieved localization! Successfully applied
Valves are one of the key equipment in LNG receiving stations, and the 14 inch and above large-diameter low-temperature butterfly valves with high technical content mainly rely on imports. On September 2nd, a reporter from Science and Technology Daily learned from the Construction Project Management Branch of China National Petroleum and Natural Gas Pipeline Network Group Co., Ltd. that the company, in collaboration with research and development partners, has successfully achieved the localization of a full series of sizes of ultra-low temperature butterfly valves for LNG receiving stations, and has been applied in the company's new national level major energy infrastructure project - the Longkou LNG receiving station project.
Six 220000 cubic meter LNG storage tanks will be built for the Longkou LNG Phase I project. It is understood that the normal working temperature of the LNG receiving station is about -163 ℃, and the valves used mainly include low-temperature ball valves, low-temperature butterfly valves, low-temperature safety valves, etc. Among them, ultra-low temperature butterfly valves can be used as regulating valves and shut-off valves, with a design temperature of -196 ℃, and are the core key equipment on LNG receiving stations.
In April of this year, the "42 inch 150 pound, 28 inch 150 pound" three eccentric ultra-low temperature butterfly valves passed the localization appraisal. The successful development of this equipment greatly reduced the investment and construction period of the receiving station. Compared with imported butterfly valves of the same specifications and functions, the cost savings of a single unit are about 60%, and the supply cycle is shortened by 40%. Only 16 42 inch butterfly valves in the Longkou LNG Phase I project can save 20.8 million yuan in funds.
