Design of welded double layer pipelines

Abstract

The methods of producing two-layer pipelines of different design, including bimetallic pipes, consisting of carbon and high-alloyed stainless steels, are investigated. It is shown that at optimum design, the welded joints in the pipes should be distributed in a zigzag order so that the welded joints on the external and internal pipes are away from each other.
