China's oil and gas pipeline localization rate reached 90%

It was learnt from the official website of China National Petroleum Corporation that the “Technology Management Department of China National Petroleum Corporation’s Mid-October, held in mid-October, held the “Measuring Conference on Major Scientific and Technological Projects for the Localization of Key Equipment for Oil and Gas Pipelines” and learned that under the support of the National Energy Administration, after two rounds of Localization of major scientific and technological projects, China's oil and gas pipeline equipment localization rate has reached 90%, investment savings of more than 20%, to promote the development of China's national manufacturing industry and the company's oil and gas pipeline cost reduction and efficiency increase is of great significance.

Since the "Eleventh Five-Year Plan" period, the rapid construction of domestic oil and gas pipelines has brought huge demand for pipeline equipment. The Party Group of China National Petroleum Corporation reviewed the situation and launched a major science and technology project for the localization of key equipment for oil and gas pipelines. Based on the achievement of the localization and engineering application of 20-MW class electric drive compressors, 30-MW class fuel-fired compressors, 40-inch and 48-inch 600-p class, 900-pound fully-welded ball valves, in 2012, CNPC The Group initiated the second round of research on localization of key equipment for oil and gas pipelines. Among the 32 companies in the United Nations, 2500 kilowatt-class oil pump units, 56-inch 900-pound fully welded ball valves, plug valves, check valves, and forced-seal valves were launched. Pressure relief valve, regulator valve, pressure regulating device 7 kinds of valves, electric, gas-liquid, electro-hydraulic 3 kinds of valve actuators, and natural gas ultrasonic and turbine flowmeters, quick opening blinds and other five types of 16 kinds of station key equipment, domestic Research and development work.

The nationalization of major science and technology projects completed the study and formulation of 19 technical conditions and test programs. It cooperated with 32 cooperative manufacturers to develop 5 types of 16 key equipments for oil and gas pipelines. A total of 40 products had 90 prototypes, of which 33 products passed China's machinery industry. The factory and appraisal jointly organized by the Confederation and the China Petroleum Technology Management Department, the main technical indicators have reached the international advanced level, and industrial trials and applications have been carried out at the Qingtie Fourth Line, the A's Independence Line, the West First Line, and the West Second Line.

The special technology project has formulated 19 technical conditions and test programs for 5 types of 16 oil and gas pipeline equipment, including 2500 kilowatts of oil pump units (motor self-lubrication); 46 patents have been applied, including 2 international patents, 12 invention patents and utility model patents. 32 pieces. Up to now, with the exception of 56-inch fully welded ball valves, quick-open blind plates, and electrohydraulic actuators, other products have undergone industrial tests and applications.
