In an industry where key asset failure can have significant consequences that reach far beyond a loss in production, Element’s failure analysis experts can help you to better understand the causes of asset failure, advise on remedial action and support you in any potential litigation you may face.

Our failure analysis services are delivered by teams of highly qualified metallurgists, chemists, materials scientists, engineers and technicians. They possess hundreds of ‘man years’ in carrying out detailed failure analyses that have occurred as a result of material defects, fracture, errant heat treatments, overloading, fatigue, corrosion, embrittlement and environmental damage and are among the most experienced and recognized in their field.

Should a failure occur, our从事专家will work with you to determine the root cause of the failure and provide you with detailed insights and recommendations to prevent the failure from occurring again, regardless of its original cause.

我们的经验涵盖了广泛的材料,并使用广泛的经过验证的故障分析技术和应用。yabo娱乐vip我们的材yabo娱乐vip料专业知识涵盖锻造,铸造和粉末金属,铸铁,钢材,铝,镍,钛,铜,镁,钼,碳钢,聚合物,橡胶,弹性体和复合材料。

It is the unique combination of our expertise in materials selection and application; manufacturing processes;骨折力学并且影响实际服务环境可以对材料或产品进行材料,使元件能够迅速提供服务失败的全面答案,并为未来的制造挑战提供实际解决方案。

Fractography服务

Materials fail for different reasons, but they fracture by four principal modes: fatigue, cleavage, dimple rupture, and decohesive rupture. Each of these modes has its own characteristic fracture appearance.

  1. 疲劳骨折是重复载荷的结果。裂缝在阶段I中引发,在阶段II中传播,并达到灾难性的骨折,包括在第III期分离。通常在高循环疲劳方面观察到垂直于裂纹传播方向的疲劳纹条件。
  2. 乳沟是一种低能量骨折,完全平坦,无特色。河流模式,羽毛标记和雪佛龙模式是裂缝中观察到的一些特征。
  3. Dimple rupture is the mode of fracture when an overload is the principal cause of failure. Microvoid coalescence is the characteristic feature observed in dimple rupture.
  4. 腐蚀性变形较小的腐蚀性破裂,涉及原子键的弱化。氢脆,应力腐蚀开裂,蠕变是解粘性破裂的一些例子。

Investigative Chemistry Services

材料的组成对它的一切 - 它持续多长时间,它是多么强烈或灵活,如何包装等。调查化学是基于材料问题可以通过检查过程,组分和所涉及的化学反应来回答材料问题。yabo娱乐vip

Element’s investigative chemists possess a unique range of experience in consulting, analytical testing, and industrial chemistry. Whether routine QA/QC assistance, material verification, or elemental analysis—or nonroutine projects such as product deformulation, identification of unknown materials, or the analysis of a failed part or product—we are prepared to work with you to explore solutions. Element serves the testing needs of all types of industries and government agencies.

元素使用以下技术和现场专用设备执行测试和评估:
  • 傅里叶变换红外光谱(FTIR)
  • Energy Dispersive X-Ray Spectrometry (EDS)
  • 气相色谱/质量选择性检测(GC / MSD)
  • Scanning Electron Microscopy (SEM)
  • Optical Emission Spectrometry (OES)
  • Differential Scanning Calorimetry (DSC)

Residue Analysis Services

神秘的污渍或沉闷,身份不明的残留物或沉积物,或者在部分表面上的腐蚀的证据 - 这些往往难以解决的问题且昂贵的问题。

元素残留分析专家培训技术可以帮助您确定野兽的性质并达到可能对您的零件或产品产生不利影响的未知物质的底部。我们的订阅专家使用分析技术的组合来表征各种类型的残留物。SEM / EDS(扫描电子显微镜与能量分散X射线光谱)分析用于确定残留物的元素组成,有时用于鉴定存在的特定化合物的XRD(X射线衍射)。当残留物似乎表现出高水平的碳或其他低能量元件时,也有时使用FTIR(傅里叶变换红外光谱),或者太薄以准确地分析SEM / EDS系统。

W.母鸡需要或需要更深入的分析,立体镜检查,SEM分析和冶金检查的组合用于表征残留物,如表面(沉积物或污渍)或在表面下方(腐蚀产品或包含在材料内)。

非金属失效分析

Polymeric materials such as elastomers, thermoplastics, composites are widely used in oilfield equipment deployed by the Oil & Gas majors across the world.

弹性(橡胶)的海豹,exposure in service to aggressive treatment chemicals and/or elevated temperatures and pressures can chemically and/or mechanically degrade the parts, resulting in irreversible change, performance deterioration and eventual functional failure of the component.The challenge is therefore to determine the root cause of failure, so that preventative and corrective actions can be implemented to ensure that it does not happen again. With over 100 years’ experience in the global Oil & Gas sector, Element has significant failure analysis experience with non-metallic components whether they are employed in upstream, midstream or downstream applications. Element has been involved in providing failure analysis services on:
  • Pumps and valves (ball, butterfly, pressure relief, bonnet, flow control)
  • 软管(沙坑,扼流圈/杀戮,抽样,柴油和饮用水转移,脐带)
  • 钻井和生产设备(压缩机,板式换热器,包装机,BOP,亚海and surface test trees, liner hangers, well tractors, swivels)
  • 天然气和化学加工管道(涂料,衬里)
  • Miscellaneous (vent plug, burst disc, pulsation dampener, hammer lug union, pig trap door, dump pit liner,harbor挡泥板,法兰垫圈)
我们经过验证的失败分析方法是通过与客户合作来利用该领域收集相关数据,以便对失败的组件的服务环境进行全面了解,例如
  • 组件位置和功能(工程图纸)
  • 材料类型和等级(数据表,部分标签)
  • 服务条件(流体,温度,压力,持续时间)
  • Design conditions (temperature, pressure, static/dynamic)
  • 以前的问题或类似组件
