EVALUATION OF THE WELDABILITY OF STEEL PIPES

Abstract

Welded metal structures are widely used in all branches of mechanical engineering, including oil and gas industry machinery. In natural gas transmission systems, steel pipes are mainly used, and their reliability and long service life largely depend on the strength of the welded joints employed and the safety of pipeline operation. These factors are closely related to the quality of the weld seam and the defects that may arise in and around the welded joint
