The Optimum Microstructure of Reheated X80 Bend Pipes

Abstract:

Bend pipes are key points in construction of pipeline. The world well known second west east pipeline project will use X80 pipeline steel in whole line. So the study on X80 grade bend pipe is very important and timely. Here , a series of experiment were done to optimize the microstructure of X80 bend pipes, and corresponding reheating technics were studied. By compare with current standard used in china, the CVN toughness and shearing area and strength were discussed. By this research, the optimum reheating program for X80 grade bend pipes were gained.
