Design and Selection of Square(Rectangular)Shape Compensator for Steam Pipeline
[Purposes]This paper aims to discuss the influence of different types of steam pipeline com-pensators on the thermal stress of the pipeline and its related parameters through detailed analysis and comparison,so as to optimize the steam pipeline design in power plant projects,which provides scientific basis and practical reference for the selection and design of compensators in similar projects in the fu-ture.[Methods]The thermal stress was simulated by constructing pipeline models of different types(square and rectangular)compensators.The analysis covered a variety of compensator configurations of different arm lengths,to assess the impact of these factors on the pipe's maximum primary stress,maxi-mum secondary thermal stress,thermal displacement,and fixed point confinement reaction.[Findings]The different types of compensators showed significant effects on the thermal stress of the pipeline.Opti-mizing the selection and configuration of compensators can significantly improve the overall stability and reliability of the pipeline system.[Conclusions]The research results of this paper can not only guide the selection of compensators for similar projects in the future,but also provide theoretical basis and practi-cal experience for improving the safety and economy of pipeline system.
