Abstract
ANGLED STEEL PIPES MANUFACTURED BY COLD FORMING ALLOW ANGLE PORTIONS AND SEAM-WELDED PORTIONS THEREOF TO HAVE HARDNESS VALUES PRETTY HIGHER THAN THOSE OF FLAT PLATE PORTIONS AND NO YIELD POINTS, ALLOW TENSILE STRESS AND COMPRESSIVE STRESS TO REMAIN IN THE ANGLE PORTIONS AND SEAM-WELDED PORTIONS, THEREBY LOWERING BUCKLING STRENGTH AND ALLOW THE ANGLE PORTIONS TO BE REMARKABLY EMBRITTLED DUE TO TOUGHNESS DEFORMATION LOCALLY REMAINING IN ANGLE PORTIONS AFTER BENDING4 THE METHOD ACCORDING TO THE PRESENT INVENTION MAKES IT POSSIBLE TO MANUFACTURE ANGLED STEEL PIPES (3, 59, 86) WHICH ARE SOFT AND HIGHLY STRETCHABLE OVER THE ENTIRE SECTIONS THEREOF, ALMOST FREE FROM RESIDUAL STRESSES, AND HAVE HIGH BUCKLING STRENGTH, EXCELLENT SECONDARY WELDABILITY AND SUFFICIENT TOUGHNESS BY HOT FORMING WITH AN ANGLED STEEL PIPE FORMING MILL (20, 25, 108).
