Support design issues after pipeline stress analysis
Thread Content
This is my first time dealing with stress analysis of steam pipelines, and I have a question for all of you experts: to what extent is the direction of thermal displacement in the analysis results related to the placement of supports? 1. For example, in the case of a sliding bracket, with thermal displacement in the axial direction of +30mm and -30mm, is the design of the bracket different? 2. The support type recommended by the stress analysis is a sliding support (see attached figures 33 and 34); there is thermal displacement in the X direction, while no thermal displacement occurs in the Y and Z directions. Is this designed in accordance with the ordinary sliding support design guidelines outlined in the Northwest Research Institute’s \"Design Manual for Supports and Hangers in Steam and Water Pipelines in Thermal Power Plants\", or are limits considered for the Y and Z directions as well?
If the horizontal displacement is axial, the amount of displacement is related to the length of the pipe insulation support; if it is radial, the pipe support must have sufficient space to prevent it from falling. The vertical displacement is mainly determined by considering the use of a spring frame, based on the forces involved.
