Control of the Integrity of Swaged Weld on Insulated Pipe-in-Pipe
Available to PurchasePublisher: Offshore Technology Conference
Paper presented at the Offshore Technology Conference, May 6–9, 2013
Paper Number: OTC-23973-MS
... Abstract In typical insulated Pipe-in-pipe (PIP) systems, both extremities of the outer jacket pipe are swaged down close to the inner pipe and are welded directly to the outer surface of the inner pipe. This full penetration weld (hereafter called swaged weld) works as a structure connection...
