通过冻结管整体抗弯试验，表明冻结管破裂失效的主要原因是接头的损坏；而内衬管对焊接头形式提高了接头强度和冻结管的变形能力，较好地解决了作为结构物和密封容器的冻结管与冻结壁的协调变形问题。

The bending strength of a freezing tube was studied by integral bending test. It isshown that major reason of the fracture failure of freezing tube is due to joint damage. Thestrength of tube-joint is raised and the deformation ability of freezing tube is improved by thejoint of an inner tube, which solves a problem for the coordinate deformation between freez-ing tube (regard as structure object and sealed chamber) and freezing wall.
