ABSTRACT:
A composite abrasion resistant, coated and abrasive containing pipe lining sheet comprises a pipe lining layer consisting from about 30 to about 70% by volume of abrasion resistant abrasive granules (preferably from about 45 to about 55% by volume of silicon carbide, alumina or alumina/zirconia granules of blocky shape, nonaligned orientation and diverse size) and from about 70 to about 30% by volume (preferably from about 55 to about 45% by volume) of a flexible organic resin binder, preferably phenolic, polyurethane, polybutadiene-acrylonitrile or epoxy resins. The pipe lining sheet can optionally be provided with a paper or textile backing bonded thereto, or with a backing of nonabsorbent, nonreactive film such as polyester, which can later be stripped off the abrasion resistant pipe lining material prior to use for lining pipes. The composite abrasion resistant pipe lining sheet can be bonded to the inner perimeter of the outer portion of a pipe by mechanical means, chemical means or a combination thereof. The abrasion resistant pipe lining sheet can be used as the innermost component for building a pipe; or it can be applied to the inside of a pre-existing pipe by adhesive means or, in the case of a metallic pipe and a composite abrasion resistant pipe lining sheet having a metallic flexible binder, by welding or brazing to the inner perimeter of the pre-existing metallic pipe.
