On April 26, 2022, the China Machinery Industry Federation and the China General Machinery Industry Association organized an on-site and video conference in Chengdu, Sichuan Province to hold a localization product prototype appraisal meeting for the "NPS32 Class600 Large Diameter Axial Flow Control Valve" jointly developed by the Construction Project Management Branch of National Petroleum and Natural Gas Pipeline Group Co., Ltd. and Chengdu Chengfeng Valve Co., Ltd.
The appraisal committee is composed of well-known experts from China General Machinery Industry Association Valve Branch, China Petroleum Society Petroleum Science Popularization Education Committee, Hefei General Machinery Research Institute Co., Ltd., the Petroleum Storage and Transportation Professional Committee of the Chinese Petroleum Society, Sichuan University, Shanghai Branch of China National Petroleum Pipeline Engineering Co., Ltd., Western Pipeline Co., Ltd. of the National Pipeline Network Group, West East Gas Pipeline Branch of the National Pipeline Network Group, Southwest Branch of China Petroleum Engineering Construction Co., Ltd. Representatives participating in the meeting include China Machinery Industry Federation, China General Machinery Industry Association, National Pipeline Network Group Construction Project Management Branch, National Oil and Gas Large Flow Metering Station Shenyang Branch, China Petroleum and Natural Gas Pipeline Engineering Co., Ltd., and Hefei Tongan Engineering Machinery Equipment Supervision Co., Ltd. and other companies.
Experts and representatives attending the meeting inspected the production and testing sites, witnessed some performance tests of the products, listened to the CHV's development summary report, reviewed relevant technical documents, and conducted detailed technical inquiries and discussions.
Finally, the experts from the appraisal committee unanimously agreed: The large-diameter axial flow control valve developed by Chengdu Chengfeng Valve Co., Ltd. has independent intellectual property rights, and its main technical parameters and performance indicators have reached the advanced level of similar international products. After industrial testing, it can be promoted and applied in natural gas metering stations and long-distance pipelines. The appraisal committee agreed to pass the appraisal.
Chengdu Chengfeng Valve Co., Ltd. has long been engaged in the production and research and development of various types of control valves, and has provided a large number of special control valve products for the national defense industry, petrochemical refining and other industries; the "NPS32 Class600 large-diameter axial flow control valve" developed this time is currently the domestically produced axial flow control valve with the largest diameter and the highest technical requirements. Its successful development and successful passing of the appraisal marks that domestic axial flow control valve technology has reached a new level. CCFV will rely on projects such as the National Oil and Gas Large Flow Metering Station to continue to make due contributions to improving the key valve equipment capabilities of my country's oil and gas pipelines and ensuring national energy security!
