摘要： PROBLEM TO BE SOLVED: To provide an anticorrosive structure of an exposed piping supporting part capable of easily executing the works at a job site without using a shrink sheet, improving the durability, and being applied in repairing and newly installing the piping. SOLUTION: This anticorrosive structure of the exposed piping supporting part has a coating layer 2 formed by solidifying a curable epoxy resin composition impregnated in a deformable base material in a state of closely abutted on an outer part of a piping part at a supporting part 4 supporting an outdoor exposed piping 1. This anticorrosive structure can be efficiently applied at a short time by winding the deformable base material while continuing the transferring of the fluid matter in the pipe without using a special device such as a by-pass piping, whereby the base material can be protected by the coating layer of high durability composed of an epoxy cured layer for reinforcing the base material, and the supporting part of the exposed piping can be stably prevented from being corroded for a long period without damaged even by the displacement caused by the thermal shrinkage, of the piping or the like.
