Research on Light-Weight of the High Pressure Heater Tubesheet

Abstract

The tubesheet is the main component of the high pressure heater, and the rationality of its design directly affects the safety and stability of the system. The light-weight of the tubesheet is conducive to resource saving, avoiding large temperature difference stress caused by excessive tubesheet thickness, and further improving parameters under the prior conditions. Therefore, the light-weight of the tubesheet has become the focus of tubesheet design research. It introduced the research of tubesheet light-weight technology from three aspects of the standard, design and material, and summarized the current research status of related literature at home and abroad. There are several problems in theoretical research and engineering application in the classification of tubesheet light-weight, including complex failure mode, experimental verification difficulties, long data accumulation, etc. It provides a direction for the in-depth study of tubesheet light-weight.
