Beschreibung
Zusammenfassung:	The present invention mitigates concentration of stress due to differences in thermal expansion and prevents damage of lining members. A lining structure (1) for a lining member (20) provided on the base material (10) of an inserted tube (3) that is used for adding a chemical to a reaction vessel (2) for leaching at high temperatures and high pressures. The base material (10) has a tube section (11) and a flange section (12). The lining member (20) is provided on the base material (10) using a material differing from the base material (10) and has a tube-lining section (21) provided on the tube section (11) and a flange-lining section (22) provided on the flange section (12). A chamfered section (13) is formed on the flange section (12). The tube-lining section (21) protrudes to the same height as the flat surface (22a) of the flange-lining section (22). The flange-lining section (22) has a curved surface (24) that protrudes toward the base material (10)-side on the chamfered section (13) and is welded to the protruding section of the tube-lining section (21) that protrudes from the slanted surface (13a) of the chamfered section (13).
