西气东输二线西段工程采用SFC阀门安全联锁系统

译文：
近期，西气东输二线工程决定采用 SMITH 流体控制有限公司 (SFC) 的阀门安全联锁系统，以期防止现场操作人员对高压容器如清管装置、过滤装置在人为维护过程中出现误操作，从而保护现场设备、人员的安全。 作为一条我国连通中亚的能源大动脉，西气东输二线工程是当前我国管道建设投资最多、输量最大、管线最长、压力最高、施工难度最大的特大工程，也是目前我国管道工程中配置要求最高，技术含量最高的管道工程。天然气长输管线，其沿途站场中的清管装置和过滤装置的高压容器需要经常进行人工维护操作，如清管器的安装和卸出，滤芯清理等。由于输送压力高（通常为 6-12MPa），同时气体中可能含有一定浓度的有毒有害气体如硫化氢、一氧化碳等，一旦发生人员带压误操作，将会造成人员伤亡和对设备及环境的严重破坏。因此，天然气管线的安全生产已经是世界各国能源企业十分重视的问题。 早在项目设计初期，SMITH 流体控制有限公司 (SFC) 便开始了与该项目的设计方：中国石油天然气管道工程公司的相关设计人员进行联络，将应用阀门安全联锁系统的深远意义介绍给项目管理人员。该产品的设计理念和安全理念得到了整个项目组的认可，并在产品应用申报过程中得到了中国石油天然气集团领导的大力支持。 SMITH 流体控制有限公司是安全联锁产品的发明者和全球最大的安全联锁产品供应商，拥有20多年行业设计和应用经验，与全球主要压力盲板、阀门和执行机构制造商都有过项目合作经验。本次西二线项目所采用的安全联锁产品，经过 SFC 公司的精心设计，配置已经达到国际先进水平。该产品安装在西二线沿线的各压气站、分输站和联络站中的清管装置、过滤和分离系统中，将阀门、执行机构、盲板之间的操作关系固化成工艺要求的顺序，使现场的操作人员无论是否经过严格培训，是否在正常工作状态，都必须在得到授权的情况下严格按照既定的顺序来操作，从而彻底避免了误操作事故的发生。该项目的应用，对国内天然气、原油、成品油等高压介质输送管线的安全生产，具有重要示范意义。 据 SMITH 公司中国区经理齐磊介绍说：“安全生产是目前我国天然气、石油、化工建设项目中考虑的首要问题，安全联锁产品在天然气管道项目中的正确应用，可以100%防止现场操作人员对高压容器如清管装置、过滤装置在人为维护过程中出现误操作，特别是针对西气东输二线这样高压天然气输送管道项目，能可靠的杜绝人为误操作，从而保护现场设备、人员的安全。安全联锁产品在欧美以及中东管道项目中已经作为标准产品大范围应用，BP、壳牌等国际石油巨头已经把安全联锁产品的应用作为强制规定写入了公司项目规范。这次西气东输二线项目，是国内首次从设计阶段就在清管装置、过滤及分离系统中采用安全联锁设计，与国际安全标准接轨，使国内的管道项目在设计、营运水平上又上了一个新台阶，意义十分重大。”

Recently, the West-East Gas Project decided to adopt a second-SMITH Fluid Control Co., Ltd. (SFC) of the valve safety interlock system, in order to prevent on-site operator of the high-pressure vessel, such as pigging device, filtration device occurred during maintenance in the human misuse, to protect the field devices, personnel security. As one of China's main artery connecting Central Asia's energy, West-East Gas Project is currently the second-biggest investor in China's pipeline construction, transmissionQJ-5 female and male stop valve for pneumatic line and the largest, longest pipeline, the pressure maximum, the most difficult construction of large projects, but also in the current configuration requirements of China's pipeline project the highest, the highest technical content pipeline project. Long distance natural gas pipeline, which along Station in pigging devices and filtration devices require frequent manual pressure vessel maintenance operations, such as the Pig of the installation and unloading, filter cleaning and so on. As the transmission of high pressure (usually 6-12MPa), while gas may contain a certain concentration of toxic and harmful gases such as hydrogen sulfide, carbon monoxide in the event of staff under pressure misuse, will result in casualties, and equipment and the environment seriously damage. Therefore, the gas pipeline safety in production is already the world's energy QJ-6 angle male thread stop valve for pneumatic lineenterprises attach great importance to the issue. Early in the project design stage, SMITH Fluid Control Co., Ltd. (SFC) began with the design of the project by: China Petroleum Pipeline Engineering Company-related design personnel to contact the valve safety interlock system will be applied to introduce far-reaching significance project managers. The product's design concept and safety concept have been recognized throughout the project team, and product applications have been reported during the China National Petroleum Group, led by strong support. SMITH Fluid Control Co., Ltd. is the inventor of the safety interlock products and the safety of the world's largest supplier of chain products, with 20 years of industry experience in design and application, with the world's major pressure on blind panels, manufacturers of valves and the implementing agencies have had the project experience of cooperation. This project used in the West second-line safety interlock products, the company's carefully designed through the SFC, the configuration has reached international advanced level. The product is installed in the west along the various second-line compressor stations, transmission stations and rendezvous points in the clear pipe fittings, filtration and separation systems, will be valves, implementing agencies, Blind solidified the relationship between the operation of the order into the process requirements , so that on-site operators, whether to undergo a rigorous training, whether in normal working condition, must receive authorization in strict accordance with the established order to operate, thus completely avoiding the misuse accident. The project application, the domestic natural gas, crude oil, refined oil, medium high-pressure transmission pipeline safety in production, has an important exemplary. China, according to the company manager of Qilei SMITH said: "Safe production is present, China's natural gas, petroleum, chemical construction projects to take into account the most important issues, security chain products in the natural gas pipeline project in the correct application, you can 100% prevent the on-site operator on pressure vessels such as the Clean pipe fittings, filters installed in the artificial maintenance of misuse arise in the process, especially QJ-7 male thread stop valve for pneumatic linefor such a high-pressure second-West-East gas pipeline project that could put an end to human misuse and reliable so as to protect on-site equipment and personnel safety . Safety Interlock products in Europe and the United States and the Middle East pipeline project has a wide range of applications as a standard product, BP, Shell and other international oil giants have been the product of safety interlock applications as a mandatory requirement for the project to write the company's specifications. The West Gas East lost second-line project is the first time from the design stage on pigging equipment, filtration and separation system used in safety interlock design, integration with the international safety standards, so that the domestic pipeline project in the design, operation level, again to a new step of great significance.
