PURPOSE: To improve workability in the manufacture of a double metallic tube and to facilitate the inspection of joined parts by reducing the projection of an extension external tube and repeating the joining of an extension internal tube, the expansion of tube, and the joining of the extension external tube. CONSTITUTION: When an internal tube 2 is expanded while the expansion of the diameter of its projected part 2a is controlled, most parts except the vicinity of the projected part 2a are closely adhered. In the state where the tip end of the internal tube 2 is joined with the extension internal tube, the projected part 2a of the internal tube 2 is not expanded in diameter, and consequently. a working space is secured in the case of joining the extension external tube to the external tube 1. By reducing the projection of the extension external tube and repeating the extension of the internal tube 2, the expansion of the tube, and the extension of the external tube 1, the freedom of the extending dimension of a double metallic tube is generated. Also, at the time of expanding the internal tube 2 and the external tube 1, by forming a space between the external tube 1 and the extension external tube, the working space is secured to improve the workability in the manufacturing, and the inspection, etc., of the joined parts is easily implemented. |

目標(biāo)：改善雙金屬復(fù)合管在制造過程中的可加工性，并且通過減弱外層鋼管的流變以及反復(fù)進行內(nèi)外層鋼管間的嵌合、膨脹等方法為兩管復(fù)合部分的檢測提供便利。 結(jié)論：在內(nèi)層管流變部分（以2a標(biāo)）的直徑增大受控條件下，當(dāng)內(nèi)層管（以2標(biāo)）膨脹時，除流變部分2a附近的金屬外，絕大部分金屬緊密附著一起而無流動。在內(nèi)層管2的末端與其延伸部分相嵌合狀態(tài)下，內(nèi)層管流變部分2a則不再膨脹，這樣對于外層管與其膨脹部分的嵌合就提供了一個工作區(qū)。 通過減弱外層鋼管的流變以及反復(fù)進行內(nèi)層鋼管2與外層鋼管間1的膨脹擴展，雙金屬管的長度可以自由控制。當(dāng)然，在內(nèi)層管2與外層管1的膨脹過程中，通過在外層管1與其膨脹部分形成工作區(qū)，可以提高復(fù)合管的可加工性，有助于復(fù)合部分的檢測操作。 |
