Leakage Analysis of Steam Condensate Pipe Elbow

Abstract

The cause of leakage of a steam condensate pipe elbow has been carried out by means of chemical composition analysis, fracture surface analysis and numerical simulation. The results show that the inner wall of the pipe at the socket welding of the downstream pipe elbow of the steam trap is not enough smooth, and the inner diameter suddenly changes, resulting in a sudden increase in the flow velocity, which increases the erosion-corrosion rate of the pipe wall, and finally leads to the elbow leakage.
