The invention discloses a thin-wall corrugated heat exchange tube suitable for supporting and welding, and relates to the field of heat exchange tube bundles. According to the thin-wall corrugated heat exchange tube suitable for supporting and welding, a transition joint of a traditional corrugated heat exchange tube is omitted, a corrugated tube body and a tube plate are directly welded, so thathidden danger is naturally eliminated; and in addition, a supporting section of a long straight corrugated structure with the length exceeding the thickness of a baffle plate is additionally arrangedfor improving the supporting effect of the traditional corrugated heat exchange tube, so that the whole corrugated heat exchange tube is supported, and the supporting firmness is improved. According to the thin-wall corrugated heat exchange tube suitable for supporting and welding, the structure is obviously superior to the structure of the traditional corrugated heat exchange tube, the manufacturing total cost is reduced, the safety is improved, the manufacturing difficulty is reduced, and the thin-wall corrugated heat exchange tube has the advantages of being reasonable in design, safe and reliable.
