Proceedings of IPC 2008 7 th International Pipeline Conference IPC2008-64017 RESEARCH OF LEAK DETECTION AND LOCATION METHOD FOR HEAT OIL PIPELINES

ABSTRACT It is an effective method to detect leak using negative pressure wave (NPW). When heat oil pipelines in low transfer throughput and complex operational changes, usually noise will be very strong and feature signal of leak is difficult to extract. The real experimental results show that the improved located formula made location accuracy from 2.5% to 1.0%
