Abstract

A corrosion resistant sleeve joining abutted ends of lined pipe where corrosive or erosive gases, fluids or slurries may flow to provide a continuous corrosion barrier between the ends of adjacent pipe liners. The sleeve is preferably a cylindrical member having sufficient length to allow disposition of a protective material, such as biocide, corrosion inhibitor, or combination thereof between the sleeve and the pipe surrounding the sleeve. The elongated cylindrical section may provide a double set of O-rings separated by a distance that would allow an annular recess to be placed between them for disposing a protective material. The protective material is preferably soluble with any fluid material that is to be transported through the pipe and blends with any fluid that permeates the outer most O-ring and comes into contact with the protective material. The protective material preferably blends with the fluid prior to penetration of the inner O-ring and thereby prevents damage to the metal pipe in the area between the adjacent liners.
