The “Development of Large Diameter and High Pressure Ball Valves for Long-distance Oil and Gas Transmission Pipelines†is one of the 50 major scientific and technological projects proposed by the group company after the “Eleventh Five-Year Plan†and is aimed at the localization of major equipment for high-pressure ball valves on the West-East Pipeline in China. Question. In November 2008, Lanzhou Petrochemical completed the design of a complete set of drawings and entered the production stage. In the production process, the elites are deployed and combined with the API certification work. In accordance with the API 6D specification and the ISO9001:2008 quality assurance system, every part of good manufacturing is completed, and after 10 months of hard work, the parts processing, assembly and gas are completed. The tests of opening and closing under dense, liquid-tight, design pressure, and high quality completed all trial production.
At present, the large-diameter high-pressure ball valve with a diameter of more than 1000 millimeters that is installed in the pipelines of the West-East Gas Pipeline Project of China is all imported, and the products are expensive and the after-sales service is difficult. The successful manufacture of this valve will break the difficult situation of relying on imported products. It indicates that the group company's equipment manufacturing has taken a new height in the field of valves.
Lanzhou Petrochemical successfully manufactured the largest prototype of high pressure ball valve in China
On the eve of “Tenthâ€, Lanzhou Petrochemical took on the largest domestic production of a 1000-millimeter oil and gas long-distance pipeline high-pressure ball valve prototype manufacturing work, all indicators have reached the design requirements. This valve is an all-welded structure with a design pressure of 100 kg/cm2.
