    • A pipe holding device includes a fixed clamp member, a movable clamp member, an upper ring and a lower ring. The fixed clamp member and the movable clamp member each have inner peripheral surfaces as metal surfaces coming into contact with the outer peripheral surface of the small diameter pipe. Furthermore, inner peripheral surfaces of cylindrical bodies correspond to a first resin surface and a second resin surface coming into contact with the outer peripheral surface of the small diameter pipe, respectively. The inner peripheral surface of the cylindrical body, the inner peripheral surfaces of the fixed clamp member and the movable clamp member, and the inner peripheral surface of the cylindrical body are adjacent to one another in an axial direction of a large diameter pipe.
    • 管固定装置包括固定夹紧构件,可动夹紧构件,上环和下环。 固定夹紧构件和可动夹紧构件各自具有与小直径管的外周面接触的金属表面的内周面。 此外,圆筒体的内周面分别对应于与小径管的外周面接触的第一树脂表面和第二树脂表面。 圆柱体的内周面,固定夹紧构件和可动夹紧构件的内周面以及圆筒体的内周面在大直径管的轴向上彼此相邻。
