Paper Number: OTC-27710-MS
... 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...
