ABSTRACT:
An anti-corrosion sealing assembly for use between a protective casement sleeve and a pipe to be protected is disclosed. The pipe extends through the protective casement sleeve such that an annular casement cavity is formed therebetween. The sealing assembly includes a muff arrangement secured between outer surface portions of the casement sleeve and the pipe at each end of the casement sleeve. More particularly, inner and outer muffs are secured about outer perimeter portions of the pipe and the casement sleeve at each end of the casement sleeve such that the outer muff totally encompasses the inner muff thereby forming a mold cavity therebetween. Each outer muff further includes a pouring spout into which a sealing compound may be poured. Furthermore, an injection tube extends through the inner and outer muffs and opens into the annular casement cavity to permit a corrosion inhibitor to be injected therein.
