    • The construction method of a steel pipe is disclosed. The construction method of a steel pipe is capable of achieving an easier construction of a steel pipe and minimizing the construction period thereby in such a manner that neighboring steel pipes are roughly arranged at a construction site, and ends of the neighboring steel pipes are held using a shaper are externally pressurized in a radial direction for thereby achieving a perfect circle shape, and then the steel pipes are arranged in a straight line shape, and the ends of the steel pipes are arranged to abut with each other or are inserted each other, so that the conjunction portions of the inner or outer surface of the steel pipe are welded.
    • 公开了一种钢管的施工方法。 钢管的施工方法能够实现钢管的更容易的构造,并且使施工周期最小化,使得相邻的钢管粗略地布置在施工现场,并且相邻钢管的端部保持使用 整形器在径向方向上被外部加压,从而实现正圆形状,然后将钢管布置成直线形状,并且钢管的端部被布置成彼此抵接或彼此插入, 使得钢管的内表面或外表面的连接部分被焊接。
