Significant progress has been made in chemical technology over the past decade; let’s celebrate the prosperity and strength of modern China. This is just a starting point – more participation from everyone will make things even more lively. Haichuan becomes even better with your involvement; we welcome everyone to join in the discussions on this forum. It’s hot in July, so be careful to prevent fires. -------------------------------------------- The first phase of the Longkou LNG receiving station has achieved a 90% localization rate for its equipment, and it has also promoted the localization of all sizes of LNG low-temperature butterfly valves, with all sizes from 8 inches to 46 inches now being produced domestically. The Longkou LNG project is the first major new energy infrastructure project undertaken by the Pipeline Network Group since its establishment. At the initial stage of its implementation, the localization rate of the components at the Longkou LNG receiving station was around 82%. In line with the group company’s unified plans to promote the use of domestic products, the project management company launched an innovative effort to achieve this goal in the Longkou LNG project, adopting a three-step implementation strategy that includes research on domestic alternatives, development of strategies for their use, and actual application and practice of those alternatives. The domesticization task force conducted investigations and visits to key domestic manufacturers in order to gain a thorough understanding of the current status of domestic production of critical equipment for LNG receiving stations, as well as the technical barriers associated with such domestically produced equipment. They identified and compiled all the key factors that determine whether a particular piece of equipment can be manufactured domestically. On this basis, a scientific strategy for the localization of equipment should be formulated, with clear targets set for the localization of key devices such as unloading arms, open-frame vaporizers, low-temperature butterfly valves, ball valves, and check valves, in order to promote the localization of important equipment in the main process systems of LNG receiving stations.
According to research, there are currently over 30 LNG receiving stations under construction or in the planning stage in China, which leads to a growing demand for related valves, with the highest demand being for low-temperature valves. In LNG receiving terminals with a reception capacity of over 2 million tons per year, there are around 2,000 low-temperature valves, of which approximately 700 are of small size. Low-temperature valves account for over 90% of all valves. Therefore, as one of the key equipment in LNG receiving terminals, valves are essential devices for ensuring their long-term, efficient, safe, and reliable operation. Due to the high technical requirements in areas such as material selection for low-temperature valves and valve sealing, most low-temperature valves at LNG receiving stations were previously imported from abroad, resulting in high procurement and maintenance costs. Construction project management companies have faced these challenges head-on, actively collaborating with research institutions and manufacturing enterprises to work together on solutions, and making vigorous efforts to promote the localization of key equipment such as low-temperature butterfly valves, ball valves, and check valves. In the process of promoting the localization of the entire range of LNG low-temperature butterfly valves from 8 inches to 46 inches, in accordance with the unified requirements of the group company, domestic products are used for low-temperature butterfly valves of 14 inches and below. Under the guidance of a construction project management company, Longkou LNG Company collaborated with domestic manufacturers that have overcome technical challenges, possess the necessary qualifications, and have applied their technologies in similar LNG receiving stations, in order to develop large-sized key butterfly valves of 14 inches or larger that require high levels of technical expertise and are currently dependent on imports. At present, led by a construction project management company and developed in collaboration with Longkou LNG Company, the 42-inch Class150 and 28-inch Class150 triple-eccentric ultra-low temperature butterfly valves have passed the domestic localization assessment, filling a gap in China’s market. Their key technical specifications are on par with those of advanced international products, and they will be deployed in subsequent LNG receiving stations ； The jointly developed 46-inch low-temperature butterfly valve is the largest domestically produced low-temperature butterfly valve of its kind used in domestic LNG receiving stations. It has been manufactured, inspected, and delivered to the project site, where it will be used in the Longkou LNG project.

This valve is way too big, haha
