Abstract

PURPOSE: To improve pressure resistance and heat insulation, by mounting reinforcing elastic bodies to fixed interval locations in the axis direction of an inner pipe.
CONSTITUTION: Bellows 11, which freely expand in the axis direction of a high temp resisting inner pipe 3 produced by inserting fibriform heat insulating materials 5 between a pressure resisting pipe 4 at the outside and the pipe 3 in a layered shape through metallic foils 6, are installed to an end surface of said inner pipe 3 by means of welding, etc. at a fixed interval. Consequently, the bellows 11 absorb thermal expansion due to the change of the inner pipe 3 into high temp while they function as reinforcing materials to pressure difference inside and outside the inner pipe 3, thus eliminating the need for an additional mechanism for considering temp change while preventing the deformation of the inner pipe 3, then somoothly distributing gas through a passage 2.
