摘　　要：钢结构管是各类海洋工程结构组块的重要构件,制管工艺的精度化程度关系着生产企业的制造水平。文章从材料的力学性能出发,分析卷管压制过程中的延展变化,基于有限元模拟方法确定焊接产生的残余应力对卷管的影响,综合影响参数确定钢板实际下料尺寸,建立卷管中压头与钢板相互作用力学模型,选取对应的压头尺寸。经现场验证对比,满足工程项目精度需求,为工程生产提供技术支持。Steel pipe is an important component of all kinds of offshore engineering structure, and the accuracy of pipe-making process is related to the manufacturing level of production. Based on the mechanical properties of materials, this paper analyses the extension changes during the rolling process of coiled pipe, determines the influence of residual stress produced by welding on coiled pipe based on finite element simulation method, determines the actual size of steel plate by synthetically influencing parameters, establishes the mechanical model of interaction between the indenter and the steel plate in coiled pipe, and chooses the corresponding indenter ruler. Through on-site verification and comparison, the accuracy requirement of the project is satisfied and the technical support for the project production is provided.
