适合服务(FFS)评估

Element’s 服务适能 (FFS) assessments help determine if your equipment is safe and fit for continued operation. 它可以防止故障，将风险降到最低，并消除昂贵的维修费用.  

评估程序由 Oil & Gas, Hydrogen, 发电、化工加工业等 完整性管理 并对承压设备的适用性进行评价. 

Element can evaluate the structural and mechanical integrity of a wide range of components to API 579-1/ASME FFS-1 international standards, 包括锅炉, HRSG, 压力容器, 化学反应堆, 储罐, 管道系统, 和管道. 从设计到退役, our 服务适能 assessments help you avoid brittle and ductile fracture and metal loss, 做出具有成本效益的运行-维修-更换决策, 并解决在组件生命周期中可能出现的问题.  

根据API 579/ASME FFS-1进行评估

Element routinely performs the API 579/ASME FFS-1 standard to assess the stability and propagation rates of different types of defects, 哪些可以在设计和服务的组件中找到. Our experts are qualified to Level 2 and 3 for NDT and metallographic replicas with specialist knowledge in 断裂韧性, 有限元分析, and 疲劳测试. 

我们的方法

设备可能存在缺陷, 成为受损, or aged so that it cannot be evaluated using the original 建设 codes. API 579-1/ASME FFS1 can be used to assess the equipment for continued operation. 它允许:

• Thermo-mechanical analysis under operating conditions (temperature and strain): normal service, 瞬变, 可预测的异常或故障服务条件. 
• Structural analysis under normal operating conditions aimed at the detection of anomalies (thickness reduction due to corrosion/erosion, subsidence/displacement of supports/anchors) to evaluate the further use and the need for any corrective actions
• Design, design verification, faulted component assessment, and requalification.
• Defects propagation rate evaluation and stability assessment for operating conditions according to recognized procedures and standards (API 579, BS 7910, DNV, NE R5, NE R6). 
• Evaluation of structural inspection results and assessment of the severity of the detected flaws
• 协助 失效分析 对故障情景的合理性进行调查和评估
