钢岔管水压试验的应力测试与分析

Test and analysis of steel bifurcation pipe hydraulic

通过对供水泵站的卜形钢岔管进行不同压力等级水压试验的应力测试及分析,以确定岔管结构设计方案的合理性和制造质量(尤其焊接质量)的可靠性。明确了U形梁腰部及闷头所受应力较大,在水压试验及供水系统运行时应注意监测;同时闷头盖板与过渡管环缝内侧所受拉力值也较大,应特别注意该焊缝的焊接质量控制,以确保供水工程系统的安全运行。

Through to the water supply pump station bligh shape steel bifurcation pipe hydrostatic test of different pressure levels stress test and analysis, to determine the rationality of the bifurcation pipe structure design scheme and the reliability of the manufacturing quality（Especially the welding quality）. Clear the u-shaped beam waist and the hard by stress is larger, the water pressure test and that should be noticed in running in the water system monitoring; at the same time the hard cover plate and the transition pipe girth inside the pull force value is bigger also, should pay special attention to the welding seam welding quality control,to ensure the safe operation of water supply engineering system.
