LINING STRUCTURE

Damage of a lining member is prevented through mitigation of stress concentration due to a difference in thermal expansion. A lining structure 1 of a member 20 is provided on a base material 10 of an insertion tube 3 used for adding a chemical to a reaction vessel 2 for leaching under high temperatu...

Zusammenfassung:	Damage of a lining member is prevented through mitigation of stress concentration due to a difference in thermal expansion. A lining structure 1 of a member 20 is provided on a base material 10 of an insertion tube 3 used for adding a chemical to a reaction vessel 2 for leaching under high temperatu e and high pressure. 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 and formed of a material different from that of the base material 10, and has a tube section lining section 21 provided on the tube section 11 and a flange lining section 22 provided on the flange section 12. A chamfer section 13 is formed on the flange section 12. The tube section lining section 21 is protruded to the same height as a flat surface 22a of the flange lining section 22. The flange lining section 22 has a curved surface section 24 protruded toward the base material 10 side on the chamfer section 13 and is welded to a protruding section of the tube section lining section 21 that protrudes from a slant surface 13a of the chamfer section 13.
