Abstract
A composite plug system and a process to repair a hole in a tubular pipe. The process includes the steps of inserting a fastener through an opening in an oblong inner plate having an elongated diameter and a shorter diameter. The oblong plate is inserted into the pipe hole wherein the elongated diameter is greater than a diameter of the pipe hole and wherein the shorter diameter is less than the pipe hole diameter so that the oblong plate is within the tubular pipe beneath the hole. An initially liquid adhesive filler is applied over the oblong inner plate over the pipe hole. An outer plate having a central opening and a diameter larger than the pipe hole diameter is affixed over the pipe hole so that the central opening receives the fastener. The outer plate is secured to the oblong inner plate and the tubular pipe with the fastener until the adhesive filler solidifies. After the filler solidifies, the oblong plate and the outer plate are structurally bonded to the pipe wall through adhesion.
