摘要：具有良好理论和实践基础及采用广泛性的美国管式换热器制造商协会标准(tema),继1978年的第六版及1982年增补后于1989年1月1日起开始发行1988年的第七版。本文对tema-78及82年增补(可统称为82年版)与tema-88版的内容进行了逐章节的对照并综合分析两者的差异,供压力容器的设计、制造、研究和标准化人员在采用国际先进标准中参考。

摘要：按照tema-9th,使用有限元分析软件ANSYS对膨胀节模型进行分析设计。简单叙述了tema-9th关于膨胀节计算的要求及关键步骤,并通过实例较为完整地对膨胀节进行了分析,对膨胀节在使用有限元分析设计中起到了指导作用。对ANSYS软件分析结果与tema-8th标准计算结果相比较,tema-8th设计值远大于有限元分析值,此标准在膨胀节的设计中仍具有较大的保守性。

摘要：某境外项目一台带有外导流筒固定管板式换热器需将换热器壳程材质由碳钢升级为不锈钢,但此方案会造成换热管压缩应力计算不通过。本文基于tema和ASMEⅧ-1UHX对换热管压缩应力进行计算,通过PVElite与HTRI软件进行换热器强度及工艺核算,对多种改造方案进行分析比选,最终确定最优方案,以满足项目要求。

摘要：In this paper a simplified approach to optimize the design of Shell Tube Heat Exchanger [STHE] by flow induced vibration analysis [FVA] is presented. The vibration analysis of STHE helps in achieving optimization in design by prevention of tube failure caused due to flow induced vibration. The main reason for tube failure due to flow induced vibration is increased size of STHE. It is found that in case of increased size of STHE, the surface area and number of tubes increases, thus the understanding and analysis of vibration becomes a very difficult task. Again it is found that flow induced vibration analysis is considered as an integral part of mechanical & thermal design of STHE. The detailed design, fabrication, testing and analysis work was carried out at Alfa Laval (India), Ltd., Pune-10.

摘要：In the first part of this paper, a simplified approach to design a Shell & Tube Heat Exchanger [STHE] for beverage and process industry application is presented. The design of STHE includes thermal design and mechanical design. The thermal design of STHE involves evaluation of required effective surface area (i.e. number of tubes) and finding out log mean temperature difference [LMTD]. Whereas, the mechanical design includes the design of main shell under internal & external pressure, tube design, baffles design gasket, etc. The design was carried out by referring ASME/tema standards, available at the company. The complete design, fabrication, testing and analysis work was carried out at Alfa Laval (India), Ltd., Pune-12. In the second part of this paper detail view of design optimization is presented by flow induced vibration analysis [FVA].
