With the development of oil and natural gas industry, the pipeline transport as the fifth largest transport mode has been thriving. The Chinese government continued to construct some large petroleum and natural gas pipe engineering, such as Chuan-East Gas Pipeline Project and West-East Gas Pipeline Project second line and so on. In the mass, the development's trend of pipe specification applied in national project is that the radius of pipe becomes bigger and bigger; the wall thickness becomes thicker and thicker; the degree of materials becomes more and more excellent. However, in the mass, the pipes specification applied in local project are that: the radius of pipe is relatively small; the wall thickness is relatively thin; they are applied in the branch of large pipe project or pipe network in city. In this paper, the working principle of pipe crawling device in oil and gas pipeline engineering and the choice and control of the primary detection technology's parameters are discussed. By analyzing the detection sensitivity, the feasibility of detecting defect using pipe crawling is demonstrated.
