載の細径電縫管製造装置。[Scope of Claim for Utility Model Registration] (1) A metal hoop is passed through a forming machine to form a pipe, and the seams of the pipe are sequentially welded using a welding machine to form a metal pipe, and beads generated during welding are In this device, the diameter of the welding machine is cut by a bead cutter and then reduced by a rolling machine, the peripheral surface shape of each of which is sandwiched between the feed passage between the squeeze roll of the welding machine and the bead cutter, and both ends thereof are flat parts,
A pair of side guide rolls each having a groove of a predetermined width formed in the center are arranged so that the bead of the metal tube immediately after welding can pass through the gap between the facing flat parts of the side guide rolls, and the groove can guide the metal tube. A small-diameter electric resistance welded pipe manufacturing device that can be set to reduce its diameter within a predetermined range. (2) The tensile strength of the metal hoop material is 40Kgf/m
The small-diameter electric resistance welded pipe manufacturing apparatus according to claim 1, wherein m is less than or equal to 2 .
