Measure temperature field in soil around a buried heated oil pipeline using probe method

During the period of preheating commissioning and start-up after shutdown of a heated oil pipeline, temperature field monitoring of the soil around the buried pipeline is performed usually. Probe method is a kind of convenient and quick soil temperature field measuring method with the superiority of not destroying the original statue of the soil around the pipeline and the temperature field established in soil. Seven on-site temperature measuring applications in Donghuang Loop Pipeline, Dongling Pipeline and Zhongluo Pipeline show that the results from measurement are reliable and temperature measuring accuracy conforms to engineering requirement. It can be used not only in temperature measurement of the soil around buried heated pipeline, but also in natural ground temperature measurement of deep buried pipeline at oil transport station.
