Claims (1)
フトを設け、該固定シヤフトに電縫鋼管端部縮管
の内面形状に合致させた傾斜縮管面を突出させて
形成すると共に、前記縮管の端口から脱出させる
ことができる面積にするため傾斜縮管面の一部に
切割除去を施してなるシワ防止型と、電縫鋼管を
介してシワ防止型の前記の傾斜縮管面に一部を密
着する円錐状の縮径型面を備えた移動縮管型とに
よつて電縫管を縮管しかつ溶接ビードとその両側
を傾斜縮管面と縮径型面により加圧する構成にし
たことを特徴とする電縫鋼管の縮管装置。 A fixed shaft is provided to relatively move the tube end opening of the ERW steel pipe, and the fixed shaft is formed with a protruding inclined pipe reduction surface that matches the inner surface shape of the reduction pipe at the end of the ERW steel pipe. There is a wrinkle-preventing type in which a part of the inclined tube shrinking surface is cut and removed to create an area that allows the tube to escape from the end port, and a wrinkle-preventing type in which a part of the inclined tube shrinking surface is cut and removed through an electric resistance welded steel pipe. The electric resistance welded pipe is constricted by a movable tube constriction type having a conical diameter constriction type surface that comes into close contact with the weld bead, and the weld bead and both sides of the weld bead are pressurized by the inclined conduit constriction surface and the diameter constriction type surface. A pipe shrinking device for electric resistance welded steel pipes.
