Study on Breakage Cause of Copper Pipe

Abstract

Copper pipe was widely used in the pipeline of seawater system. Comprehensive characteristics of pipe were analysed. Pressure and velocity were selected as representations of primary static and dynamic characteristics of the pipeline; the breakage reason of water supply pipe was studied through flow field simulation analysis and pipeline metallographic analysis. There was a phenomenon of excessive flow velocity and obvious erosion corrosion in bending pipe; the result showed that erosion corrosion is the direct cause of pipeline breakage. By improving the copper pipe manufacturing press, increasing the pipeline size and bending radius can effectively prevent pipeline damage.
