Abstract
Provided is high corrosion resistant equipment for a plant having the lining structure which exhibits high reliability against breaking of a joining portion over a long use period. The high corrosion resistant equipment for a plant includes a lining plate and a support portion which are made of a high corrosion resistance material and a structural material portion made of a steel material or the like. The lining plate and the support portion include a joining portion to which friction stirring is applied. The support portion is assembled into or fastened to the structural material portion by means of the geometrical structure with a gap interposed between the support portion and the structural material portion. Due to such a constitution, high corrosion resistant equipment for a plant having the lining which exhibits high reliability can be acquired.
