Fracture Control of Gas Pipeline

Fracture control is a key mission for the integrity of gas transmission pipeline.Ductile fracture in gas pipelines is an extremely complex process consisting of crack initial and propagation.Fracture control of gas pipeline requires the pipe has sufficient fracture toughness to resistance to fracture initiation and propagation.In this paper,some issues and main concerned problems for the fracture control of gas transmission pipeline were introduced and discussed.
