Dept. of Transportation. Pipeline and Hazardous Materials Safety AdministrationPipeline Research Council InternationalUS Transportation CollectionLong-distance high-strength pipelines are increasingly being constructed for the efficient transportation of energy products. While the high-strength pipeline steels and high productivity welding processes are being applied, the procedures employed for pipeline property specification, welding procedure qualification, and weld integrity assessment remain largely unchanged, particularly from the viewpoint of actual pipeline construction. A significant body of knowledge exists in limited circles of researchers and a minority of large energy companies. However, the broad industry does not benefit from this knowledge until the relevant codes and standards are updated. The use of existing codes without proper consideration of the unique features of the modern high-strength pipeline can lead to higher costs, or, in some cases, reduced safety margins
