The focus of this project is on the use of Type-B sleeves to enhance the strain capacity of girth welds. This enhancement option was selected by the project team at the start of the project. In addition, the project team chose to examine this enhancement option on the girth welds of vintage pipelines.
The objectives of this project are to: (1) examine Type-B sleeves for enhancing pipeline strain capacity and (2) develop recommendations to properly apply Type-B sleeves.
