Lanzhou Petrochemical successful production of the nation's largest high-pressure valve prototype
原文：
HC Pump Net:"11," the eve of commitment made by Lanzhou Petrochemical maximum diameter of 1,000 mm, high-pressure oil and gas long-distance pipelineBallPrototype manufacturing work is completed, the indicators have reached the design requirements. This setsValvesFor the whole welded Hydraulic control valvesstructure, the design pressure of 100 kg / square centimeter.
"Long-distance gas pipelines large-caliber high-pressure ballValveDevelopment "project is the group's" Eleventh Five-Year "after 50 years one of the major scientific and technological research is directed at ChinaWest-East GasHigh-pressure valve on the pipeline equipment, localization of the major issues. In November 2008, Lanzhou Petrochemical completed a full set of drawings Water Control valves of the design into the production phase. In production, it transferred the crack, combined with API certification, in strict accordance with API6D specifications and ISO9001: 2008 quality assurance system to every aspect of well-made, after 10 months of hard work, completed spare parts processing, assembly and gastight , liquid density, design and so on under the pressure of the opening and closing test, high-quality finish all the work trial.
At present, China's West-East GasEngineeringPipeline supporting more than 1,000 mm large-diameter high-pressure valve all the dependence on imports, and Cast Gate, Globe, Check Valves the product is expensive, after-sales service difficult, TaiwanValvesManufacturing success, will break the dependence on imported products, a difficult situation, but also marks the group equipment manufacturing in the area of the valve station to a new level.

“十一”前夕，由兰州石化承担国产最大的，直径达到1000毫米的油气长输管线高压球阀样机制造工作全部完成，各项指标均达到设计要求。这台阀门为全焊接式结构，设计压力为100公斤/平方厘米。
《油气长输管线大口径高压球阀研制》项目是集团公司提出的“十一五”后三年50项重大科技攻关项目之一，是针对我国西气东输管线上高压球阀的重大装备国产化课题。2008年11月，兰州石化完成了全套图纸的设计进入生产阶段。在生产中，抽调精兵强将，结合API认证工作，严格按API6D规范和ISO9001∶2008质量保证体系把好制造的每一环节，经过10个月的艰苦奋战，完成了零配件加工、装配和气密、液密、设计压力下的开闭等试验，高质量的完成了全部试制工作。
目前，我国西气东输工程管线配套的超过1000毫米的大口径高压球阀全部依赖进口，并且产品价格昂贵、售后服务困难，这台阀门的制造成功，将打破依赖进口产品的困难局面，同时也标志着集团公司装备制造在阀门领域站上了一个新的高度。
