元素’s Fitness for Service (FFS) assessments help determine if your equipment is safe and fit for continued operation. It prevents failures, minimizes risks, and eliminates costly repairs.

Assessment procedures are used by the Oil & Gas, Power Generation, and Chemical Processing industries forintegrity management并评估含压力设备的健身。

元素可以评估各种组件的结构和机械完整于API 579-1 / ASME -1国际标准,包括锅炉,HRSG,压力容器,化学反应器,储罐,管道系统和管道。从设计到退役,我们的服务评估的健身有助于避免脆性和韧性骨折和金属损失,使成本效益的运行修复 - 替换决策,并解决各种生命周期中可能出现的问题。

API 579 / ASME FFS-1

元素经常执行API 579 / ASME FFS-1标准,以评估不同类型缺陷的稳定性和传播速率,可在设计和服务中的组件中找到。我们的专家有资格获得2级和第3级,对于具有专业知识的NDT和Metallographic Replicas断裂韧性,finite element analysis [FEA], 和fatigue testing.

Our approach

Equipment may contain flaws, become damaged, or aged so that it cannot be evaluated using the original construction codes. API 579-1/ASME FFS1 can be used to assess the equipment for continued operation. It allows:

  • Thermo-mechanical analysis under operating conditions (temperature and strain): normal service, transients, predictable exceptional or faulted service conditions.
  • 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
    协助失败分析调查和评估失败情景的合理性

我们的FFS评估服务

  • Boiler and heat recovery steam generator components (headers, drums, etc.)
  • 管道(水/蒸汽管道,工艺管道,乒乓球等)
  • 涡轮机(转子和外壳)
  • Other plant components (pressure vessels, valves, pipes, tubulars, furnaces, reactors, heat exchangers, etc.)
Fitness For service (ffs)

FFS on generator rotor retaining rings

元素performs FFS testing on generator retaining rotor rings to avoid catastrophic failure of the generator and associated turbines. We can perform analysis to evaluate the reliability of the retaining ring to establish the need for repair or replacement.

FFS evaluation of the components of energy production, processes and power plants

元素has a wide range of knowledge including structural analysis, materials science, and control techniques, to perform FFS evaluation and reliability assessments of the components for energy production, the process supports/anchors, and power plants.

Plant components may contain defects during manufacturing processes and service life, which reduces the initial degree of safety and integrity with which it was designed.

Energy production, process, and power plants such as nuclear power plants (NPP) and Hydro Power Plants, which often use complex systems, are located in adverse environments and interact significantly with the population residing in the neighboring territories and with other infrastructures such as roads and railways. For these reasons, safety aspects play a fundamental role in all phases of their life cycle; design, fabrication, construction, service, operation and decommissioning.

We can assess component stability according to internationally recognized procedures and regulations, and not only refer to actual defect or material conditions but also consider their future evolution in normal service conditions.
