The detection of oil and gas pipelines is an important means of forecasting potential accidents and providing the basic data for safety assessment. The overseas application has been well applied in practice. Oil and gas pipeline testing is to predict potential accidents, safety assessment provides an important means of basic information. Regular inspection and test of oil and gas pipelines is an important measure to achieve safe operation and management of pipelines and has been well applied in practice. As the oil and gas pipeline station site pipe network is usually designed with complex shapes and with a variety of elbows, manifolds and tees, the accessories may also have a complex shape with a variety of accessories, exhaust pipe, reducer And nozzles, resulting in a much more complicated stress distribution and local stress concentration than the main line pipe. Making the traditional detection and evaluation technology can not be well applied.
