... steel pipe, using a hydroforming process. Between the two pipes a glue is coated to produce adhesion. The pipe ends are welded using a weld overlay method. The main development work was finding a solution of the welding at a glued pipe end. This was successfully done. The result is a glued linepipe...

... Pressure & High Temperature applications. In order to meet tight Hi-Lo requirements together with high fatigue performances, innovative Pipe End Design and associated automatic welding procedures were developed and qualified. The paper describes the complete sequence of pipe manufacturing process, from hot...
