On April 8, Sichuan Zigong High-Pressure Valve Co., Ltd. planted in front of the gates and firecrackers blazed. Three trucks carrying 19 sets of the first large-diameter all-welded forged steel pipe ball valve manufactured by the company slowed down. Out, west to east to the Huai (yang) - Wu (Han) pipeline construction site drove. This is the first time that the West-to-East Gas Pipeline project has adopted domestically produced products, which indicates that the manufacturing technology of China's large-diameter all-welded forged steel pipe ball valve has reached the international level. Experts claim that this is another major domestic equipment in China's large-scale projects. model.
Huai-Wu Pipeline is an important branch pipeline project of the West-East Gas Pipeline with a total length of approximately 460 kilometers. According to Wang Yijian, Deputy Manager of the Project Department of West-East Gas Pipeline Huai-Wu Pipeline Company, an all-welded pipeline ball valve is installed every 30 km to 50 km in the West-East Gas Pipeline project. Due to the high pressure in the gas transmission pipeline, the materials and manufacturing technology requirements for the valve are extremely high. Before this time, all of the western-to-east gas transmission projects in China were imported similar products.
Zigong High Pressure Valve Co., Ltd. is currently part of the Sichuan Haojia Group and is a company with more than 40 years of valve production history. Its production and R&D capabilities are among the leading players in the domestic industry. In 2001, the company undertook the national key project for the major equipment of the national large-caliber all-welded forged steel pipe ball valve. The company invested heavily in the introduction of advanced ball valve manufacturing technology from the US GE New Billund Company, and imported advanced ball valve welding from Italy. Equipment, in the technical equipment has the ability to design and manufacture special process valves and pipeline valves. In March 2002, the company successfully prototyped the first 40â€-600 LB full-welded forged steel ball valve in Asia and passed the appraisal of AQSIQ and China Machinery Industry Federation. In June 2002, it attracted worldwide attention. In the international bidding for the main line of the West-East Gas Pipeline Project, the company is the only company in the country that can produce large-diameter all-welded ball valves. It competes with six foreign companies, including Cameron and the Italian Grove, on the same stage. The participation inhibited the high-price bids of foreign companies and saved a lot of foreign exchange for the country. It was awarded the “Outstanding Contribution to the West-East Gas Transmission†award by the Western Economic and Technical Leadership Group of the State Council.
It is understood that the all-welded forged steel ball ball valve represents the world's highest level of valve production and development direction. The ball valve has a service life of more than 30 years and can be widely used in petrochemical industry, urban air pipe network, oil and gas pipelines and other fields. .
