Abstract

PURPOSE: To realize simple and strong welding, when welding a steel pipe to a joint such as flange, by providing a ring notch step part in vertical tube piece, press- fitting the connection end part of steel pipe into said piece, and simultaneously welding two sides, namely, the butt end and the butting face on the outer circumference of notch step part.
CONSTITUTION: A ring notch step part 3 tapered in the end outer circumferential face is provided in a vertical tube piece 2 which is vertically erected from the inner circumferential edge of a ring collar 1 of a joint metal H. The connection end part of a steel pipe A is press-fitted and fixed to this notch step part 3, and the but tend a-b of steel pipe A and ring notch step part and the butting face b-c between the connection end inner circumferential face and outer circumferential taper face of notch step part 3 are welded simultaneously so as to weld the steel pipe A and the joint metal H.
