INVESTIGATION OF ELEMENTS RESPONSIBLE FOR INNER WELDED RIB DEFECTS ON SMALL AND MEDIUM-SIZED STRAIGHT-SEAM WELDED STEEL PIPES AND RELEVANT COUNTER-MEASURES
The elements responsible for inner welded rib defects existing on small and medium-sized straight-seam welded steel pipes are analyzed, based on which it is concluded that such defects can be prevented effectively by improving pass design, forming technology, welding technology and strip quality.
