Cold-bending forming buckling-type seam joint pipe
The invention discloses a cold-bending forming buckling-type seam joint pipe, and belongs to a cold bending forming pipe which is used in a light weight structure or mainly achieves a decorating effect. The cold-bending forming buckling-type seam joint pipe comprises a seam which is formed in a pipeline of which the thickness is not greater than 3 mm in the direction parallel to the pipeline; a left buckling opening which is curled downwards by 180 degrees is formed in the left edge of the seam; a right buckling opening which is buckled with the left buckling opening is formed in the right edge of the seam. The cross section shape of the pipeline is a rectangle, a round, an oval and a mutant of the round and the oval; an angular inward concave part, an angular outward convex part, an arc-shaped inward concave part, an arc-shaped outward convex part, a square inward convex part and/or a square outward convex part are arranged in the longitudinal direction of the pipeline. The pipe is buckled without welding and convenient to customize and machine in the field; the pipe has the characteristics that the welding seam corrosion is avoided; the service life is long; the mechanical strength of the pipe is higher than that of a single circular pipe; the decorating effect is good and the like.
