Research on Gas Station of Pipeline for Nondestructive Testing Technology

Southwest Oil and Gas Field mainly emphasis on natural gas development, especially gas well with high sulfur content makes station detection and evaluation of the safety of pipeline particularly important. This study use guided wave and phased array ultrasonic[1] testing technology to perform Nondestructive Detection of Pipeline for four South stations of Sichuan gas field, finding 381 defects, meanwhile providing a complete set of technology for gas pipeline nondestructive detection system.
