Abstract:Measurement and calculation of pipe bending angles are often needed as long-distance oil and gas pipelines crossing through hill, gully or river, and their accuracies affect the quality of following working procedure. This article analyzes the importance of measuring pipe bending angles in the construction of longdistance pipeline, with an emphasis on two measurement and calculation methods of pipe bending angles, i.e.the same slope method and the different slope method. The practical application of the methods is explained through one example, and some problems for attention in practical measurement are stressed.
