The key valve and compressor anti-surge valve of large-diameter pressure regulating device successfully passed the appraisal

[ China Instrument Network Instrument R&D ] On December 18-19, 2018, China Machinery Industry Federation and China General Machinery Industry Association were commissioned by the National Energy Administration to host the key valve and compression of natural gas large-diameter pressure regulating device in Tianjin. Machine anti-throat valve new product appraisal meeting." The meeting identified the key valves and compressors of the large-diameter pressure regulating device jointly developed by Tianjin Betel Fluid Control Valve Co., Ltd. and China National Petroleum Corporation Pipeline Branch and China National Petroleum Corporation West-East Gas Pipeline Branch. Anti-thorch valve new products. The valve is the key valve of the pressure regulating device with the highest pressure and the largest diameter in China.

Experts from the appraisal committee inspected the production and test site of Tianjin Betel Valve Factory. Experts witnessed the factory test of the product prototype. At the meeting, they heard the expert representative factory test witness report and Tianjin Betel and the pipeline branch, and the West-East Gas Pipeline. The joint development summary report, consulted the relevant design, manufacturing, testing and quality assurance documents. After discussion, the appraisal committee considered that the key valves of the large-diameter pressure regulating device (DN600, DN400 Class900 cylinder drive safety shut-off valve, electric axial flow regulating valve) and DN400 12MPa cylinder drive axial compressor anti-surge valve were developed. Domestic blanks, the main technical parameters and performance indicators have reached the international advanced level of similar products. After further improvement, it will be put into industrial operation in the form of China-Russia pipeline and other projects.

Under the leadership of the National Energy Administration, this localization task was jointly promoted by China National Petroleum Corporation and China National Machinery Association. It is one of China Petroleum's major science and technology projects, “Localization of Key Equipment for Oil and Gas Pipeline”, and is the first successful acceptance in March 2016. The continuation of the first phase of the key valve of the pressure regulating device DN300 below 12MPa. The first phase of the domestically produced valves has been successfully applied to major projects such as the Shaanxi-Beijing four-line and the West-East Gas Pipeline Transformation. This year, the company won the bid for the northern section of the Sino-Russian East Line and the West Third Line. Pipeline project. The company will continue to insist on technological innovation as the core engine of the company's development, continue to increase investment in research and development, continuously develop new products, do its utmost for the country's energy security, and instill inexistently for the sustainable development of Bosite-Betel. power!
