Title:
NUCLEAR-GRADE PIPELINE SUPPORT ARRANGEMENT METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/197543
Kind Code:
A1
Abstract:
The present invention provides a nuclear-grade pipeline support arrangement method and apparatus. The method comprises: acquiring a target zone where supports can be arranged on pipelines; in the target zone, selecting a position where a pipeline has a maximum displacement under seismic conditions to arrange a damper step by step, until the seismic stress of the pipelines is small enough to meet standard requirements of the seismic conditions; and replacing the damper having a minimum displacement under thermal expansion conditions among all the dampers with a rigid support step by step, until the maximum thermal expansion stress of the pipelines does not exceed standard requirements or there is no remaining damper, so as to obtain a target support arrangement scheme. According to the method, the problems in the existing nuclear-grade pipeline support arrangement methods that blindly arranging expensive dampers takes a long time and lacks systematicness, and it is difficult to achieve optimal selection of pipe support types can be solved.
