Abstract

When gas transmission pipelines are working, due to being heated or cold and expansion and contraction, the pipes will produce thermal stress. Thus the stress poses a threat to pipeline working. Therefore, this article will adopt the method of model simulation and establish a channel space finite element model, then the ANSYS finite element analysis software will be applied to the calculation of thermal stress of the pipelines.Finally, we will do some research and analysis of the factors affecting the thermal stress in pipeline.The results show that the temperature had a greater influence on the thermal stress of pipeline, when the larger internal and external temperature difference of the pipeline get, the greater thermal stress the pipes produce. Secondly, the wall thickness of pipelines also affects thermal stress. Under the condition of the constant pipe diameter, thermal stress produced by pipes becomes small with the increase of pipe wall thickness.Lastly, with the fixed constraint on one end of the pipeline, the produced thermal stress is significantly larger than unconstrained condition and situation of constraints on two ends, etc.So it is suggested that the space between anchor blocks on pipelines cannot be too small, which means we should minimize that condition of the fixed constraint on one end of the pipeline.
