Beschreibung
Zusammenfassung:	The utility model provides a heat exchange tube clamping device for heat exchange tube butt welding, has a three roller that is used for the cooperation to clip two heat exchange tubes simultaneouslyalong its circumference, and three roller parallel and three roller homoenergetic mutually rotates around self axis, and the cooperation forms a column passageway that is used for placing the heat exchange tube between the three roller, and the column passageway matches and cuts with three roller homogeneous phase with the external diameter of heat exchange tube, three roller middle part all is equipped with one section changeover portion, the external diameter of changeover portion is less than the external diameter that is used for cliping the circumference of heat exchange tube on the roller, the epaxial changeover portion of three roller is followed the axial position of roller and is corresponded each other, so that all reserve out the required space of welding set welding between thechangeover portion of thr
