A Study on Pipe Specification for Long Distance Transmission Pipeline in Arctic Area

One of the important factors to consider when designing long-distance natural gas high-pressure pipeline in arctic environments is the establishment of pipeline fracture control measures. The methods used for prediction of ductile fracture propagation of gas pipeline are simple numerical solution, Battelle two curve method, and full scale pipe burst test. In this paper, we investigate the requirements of pipe material applied to the arctic pipeline in Russia, and compare the pipeline design application cases with the three methods of setting the required value of pipeline material fracture toughness. It is considered appropriate to apply the BTC method incorporating the correction factor.
