With the development of China's coal chemical industry and natural gas liquefaction industry, the localization of key equipment required is gradually deepening. Although the 100000m3 air separation unit has been successfully used in Shenhua Ningmei, a large number of low temperature pump and valve products supporting large air separation units and LNG have been imported. To this end, China General Machinery Industry Association held a seminar in Beijing on November 17, inviting relevant leaders and experts from Hangzhou Oxygen Generation Group Corporation and Sichuan Air Separation Group Corporation to introduce the market demand and technical requirements of air separation units and natural gas liquefaction units for pump valves, and discussed with the technical directors of the pump valve enterprises attending the meeting.

After introduction and discussion, the participants agreed that: after nearly 30 years of development, especially the promotion of localization of major equipment such as long-distance pipelines and ultra supercritical thermal power units, China's pump and valve industry has made leaps and bounds in recent years, and has the ability to undertake research and development of pump and valve for air separation units and natural gas liquefaction units, as well as the ability to supply products.

The meeting was chaired by Huang Li, President of China General Machinery Industry Association, and attended by Sui Yongbin, Honorary President of China General Machinery Industry Association, Song Yinli, Deputy Secretary General of China General Machinery Industry Association and Secretary General of Valve Branch, and Xu Jianping, Deputy Secretary General of China General Machinery Industry Association and Secretary General of Gas Separation Equipment Branch. Yang Tiecheng, Director of the Major Office of the China Machinery Industry Federation, was invited to attend the meeting.

Huang Huichang pointed out that Hang Yang and Chuankong played an important role in the localization of air separation equipment and fulfilled their mission and made outstanding contributions to the localization of natural gas liquefaction units. The introduction of the requirements and technical requirements of air separation units and natural gas liquefaction units for pump valves for pump valve enterprises will positively promote the localization of pump valves. At the same time, it is pointed out that the pump valve market is very large, and whether the order can be obtained depends on the technical level and supporting capacity of the pump valve enterprise; The pump valve products of air separation unit and natural gas liquefaction unit are technically difficult, but mainly depend on the efforts of the pump valve industry; It is suggested that competent pump valve enterprises, air separation equipment manufacturers, relevant design institutes and users should jointly develop high-quality pump valve products supporting air separation units and natural gas liquefaction units, develop prototypes, and the Association should organize new product identification in conjunction with user units.

President Huang Li made it clear that China General Machinery Industry Association started to promote the localization of pump and valve products for air separation units and natural gas liquefaction units today. President Huang was in charge, and honorary President Sui Yongbin served as the general consultant. Secretary General Song Yinli and Secretary General Xu Jianping were specifically responsible for liaison and coordination, so as to formulate localization plans as soon as possible, and planned to carry out the localization of pump and valve products for cryogenic devices step by step.
