  • Preventing Corrosion Or Incrustation Of Metals (AREA)

Abstract

PURPOSE: To eliminate oil film removing of torichloroethylene flashing, and to make a duplex pipe heat exchanger by means of pickling the outside and inside of the steel pipe, neutralizing and flashing it by water, carbureting at normal temperature, and providing the primary rust-proof by volatile corrosion inhibitor that brings film on the surface of the metal to prevent corrosion.
