Propagating Shear Fracture in Natural Gas Transmission Pipelines

Source

The propagating shear fracture in natural gas transmission pipelines can be theoretically analyzed, and the crack velocity and propagation distance can now be calculated. The propagation theory has a good consistency with the experimental results for 1219 mm (48 in.) outside diameter (OD) × 18.3 mm (0.72 in.) wall thickness (WT) line pipes, and it predicts the notch ductilities of line pipes required for arresting the fracture according to the type of the gas, the acceptable fracture length, the pipe size, and the design stress of the pipeline.
