Abstract

PROBLEM TO BE SOLVED: To provide a removable outer case which has no part easily influenced by corrosion when exposed to a flow of hightemperature fluid containing dust by arranging it in such a manner as to be axially movable on a second tubular part so that an inner case can be touched by a hand from the outside. SOLUTION: In order to make a section removable, an outer case 16 has tubular first part 23 and second part 24, and the first part 23 is at least partially superposed with the second part 24 in the middle area of the section. In the end part of an inner case 17 exposed when the first part 23 is moved on the second part 24, the inner case 17 comprises a joint 38 in a part where the inner case 17 is connected to the part of a pipe wall. The inner case 17 is divided into two lengths 17a, 17b connected by a joint which can be touched from the outside, and one length 17b is separated and removed, whereby a joint 39 can be touched by other methods.
