April 8 is a memorable day for China's valve industry. On this day, Sichuan Zigong High Pressure Valve Co., Ltd. (Zigong High Valve) officially launched the first full-diameter all-welded pipe forged steel ball valve for Huaiwu Branch of the West-East Gas Project and sent it to the construction site. Since then, domestic-made valves have been adopted for the first time in the project of West-East Gas Pipeline, marking that the large-diameter all-welded pipe forged steel ball valve, which has been monopolized by foreign countries, will no longer rely on imports from this point of view and also indicates that the R & D and manufacturing level of China's valve industry is on the rise again A new level. As the high-tech enterprises in Sichuan Province, Zigong high valve is the predecessor of Zigong City General Machinery Factory, the company has developed more than 40 years of valve manufacturing history, has been focused on the production of high temperature, high pressure and long-distance pipeline The valve. Under the impact of the tide of market economy, the inflexible mechanism of state-owned enterprises has become the bottleneck restricting the development of enterprises. In order to meet the needs of the development of the market economy, in 1998, Zigong High Valve joint-stock reform, Sichuan Wojia Group 84% of the shares to buy shares to become shareholders, and Zigong high valve only 16% of the shares. After the restructuring of Zigong high valve directly to the national key project - West-East Gas Pipeline Project. In order to meet the needs of the West-East Gas Pipeline Project, in 2001, Zigong High Valve invested heavily in the introduction of the United States (GE) New Billumbo's today's ball valve manufacturing technology, and in March 2002 the successful trial of Asia's first model 40 -600LB large diameter all-welded forged steel ball valve. For this product, China Machinery Industry Federation, Deputy Secretary-General, Major Office Director Sui Yongbin at the appraisal meeting made a high rating. He said: "The successful development of this product has filled in the blank of the domestic large-diameter ball valve products and made positive contributions to the manufacturing localization goal of major equipment." Opportunity always reserved for those who are prepared 2002 6 In the international bidding for the main pipeline of the West-East natural gas transmission project that attracted worldwide attention, Zigong High Valve, as the only bidding enterprise in the domestic large-caliber ball valve manufacturer, competed with seven foreign-funded enterprises such as Cameron in the United States and Grove in Italy. On the same stage "competitive." "Although there was no successful bidder at the time, our country has effectively reduced the high bidding for foreign investors, saved huge amounts of construction funds for the country, and won the honor of being the only outstanding contribution made by the State Council to the West-East Gas Pipeline in the domestic valve industry because of our participation. State Zigong high valve in the construction of West-East Gas Project made a positive contribution to the contribution. "Zigong high valve bamboo Shao Yu said. After the failure of bidding for the main west-east gas pipeline, Zigong High Valve has not been discouraged. They devote themselves to assimilating and reintroducing the imported technology and developing all-welded pipeline valves of different specifications, which are obtained in the construction of urban pipe network reconstruction project Successful application. In recent years, the West-East Gas Pipeline Project is set off a new round of construction boom, Zigong high valve keenly aware that new business opportunities come again. Opportunity awaits those who are prepared. One day in the first half of 2005, a mysterious phone hit the sales department of Zigong High Valve Co., Ltd., claiming that due to the explosion at the filling station of Karat-2 gas field in Xinjiang, the valve was also damaged in this accident and it was in urgent need of several all-welded large diameter ball valves . Faced with this emergency, the company's employees from top to bottom agile, in the shortest possible time to meet the requirements of the valve sent to the scene of the accident, to solve the Kela two gas stations plus the pressing need. The move won the trust of the National West-East Gas Pipeline Leading Group Procurement Office and won the order of 19 all-welded forged steel pipeline ball valves for West-to-East Huaiwu Pipeline Network project. Valve industry has been upgraded to technology According to the West-East Pipeline Company Huai-wu pipeline project manager Wang Yi Jian introduction, Huaiwu pipeline project via Henan and Hubei provinces, a total length of about 460 km, due to long lines, terrain and complex, Therefore, the pipeline requires high safety standards. "For the first time, the all-welded pipe forged steel ball valve is applied on the Huai-wu branch of the West-East Gas Pipeline and has a landmark significance in the history of valve manufacturing in China, indicating that China's valve development capability has reached the international advanced level," said Wang Yi-jian. According to reports, Zigong high valve in the tight schedule, the task of heavy production of products, third-party supervision --- Hefei Institute of General Machinery Valve Institute Songzhong Rong, senior engineer, said: "Through the introduction and digestion Japan (KTM) and the United States (GE) New Billumbi valve advanced technology, in strict accordance with the United States API6D-2002 norms and ISO9001 quality assurance system manufactured this product, the test fully in line with the construction of Huai-wu West Extension Project The product also marks the long-term has been monopolized by the all-welded pipe valve from no longer dependent on imports. "Beijing Valve Plant chief engineer Lu Peiwen said that although the Zigong high valve shipped the product is only used in the West East Branch, but it has won the right to speak for China's valve manufacturing enterprises. He said that at present the country is actively promoting the domestication of a batch of national key engineering equipment such as 1 million tons of ethylene, coal liquefied oil, 10 million ton refinery, large-scale thermal power station and nuclear power station, which also provides the valve industry with new opportunities . As used in these projects on the valve products are both high temperature, high pressure, but also good sealing performance, at present a lot of products also fail to meet the requirements, so you need the domestic strength, technically superior enterprises to increase the field The pace of product development, in order to meet the needs of the state's key construction projects. Deputy General Secretary General of China General Machinery Industry Association Valve Secretary General Song Yinli told reporters: "Recently, the state has promulgated a series of rejuvenation of major equipment files, the manufacturing sector is a good news, but the key is still to give users In the past, some products produced by domestic enterprises did not reach the level of foreign countries, but in recent years by continuously strengthening independent innovation, the overall technical level of China's valve industry has been enhanced. "Here said he hopes that some qualified enterprises Give full play to the advantages of the valve industry, high-end product research and development and manufacturing capabilities to further improve, to truly be able to assume the state's key projects. Opportunities and Challenges According to incomplete statistics, during the construction of the West-East Gas Pipeline, a valve needs to be installed every 20 to 30 meters in the more complicated terrain. A valve should be installed at each end of the tunnel and the river course, Other locations need to install a valve every 30 to 50 meters. This calculation, the total length of more than 20,000 kilometers of West Gas Pipeline construction needs of the number of valves can be imagined. However, Wang Yi Jian reminded valve manufacturers, although the construction of the West-East Gas Pipeline Project will be completed by the end of 2010, foreign manufacturers have moved their research and development centers and manufacturing bases to China in recent years. Under the premise of ensuring the same product quality, Reduce the cost of production, the price advantage of domestic enterprises gradually. Therefore, the bidding for the next West-East gas pipeline is both an opportunity and a challenge for domestic enterprises.
