Abstract

Abstract A pipeline repairing kit comprising (a) a sealed, flexible envelope; (b) two removable means dividing said envelope into at least first, second and third compartments, said means being removable selectively to connect the first and second and third compartments without opening the sealed envelope; (c) measured quantities of the parts of a two-part curable resin system in the first and second compartments; and (d) an elongated flexible bandage member made of absorbent material disposed in said third compartment, said member including an integral closeable vent, whereby an elongated resin-soaked flexible bandage member adapted for wrapping around a pipeline can be provided by first removing the removable means between said first and second compartments to thereby mix the parts of the resin system, next removing the other removable means and bringing the mixed resin into intimate contact with said elongated flexible member, and then manually manipulating the envelope so as to thoroughly impregnate said bandage member with mixed resin before the envelope is opened.
