  Fracture control technology plays a very important role in structural integrity and safe operation of high-pressure,large-diameter gas transmission pipelines.Existing fracture control technology includes methodologies to control brittle fracture,ductile fracture initiation,and ductile fracture propagation for gas pipelines.The biggest challenge these fracture control technologies face today is that the approaches developed 40 years ago for ductile fracture propagation control has not worked for modern pipeline steels.Over the years,extensive efforts have been made worldwide to this area,but a new technology to control ductile fracture propagation is still needed for modern high-strength pipeline steels.For this purpose,the present paper makes a critical technical review on various existing methods developed for ductile fracture propagation control for gas transmission pipelines.
