  • Patent number: 4997613
    Abstract: A method and apparatus are shown for lining a tubular member with an elastomeric liner having an outside diameter which is initially greater than the inside diameter of the tubular member and a length which is greater than the length of the tubular member. A length of the liner is reduced to a downsized outside diameter and inserted into the tubular member to be lined. The liner is allowed to expand to substantially its original outside diameter to thereby bond the liner within the tubular member, the liner opposite ends still extending outwardly from the opposing ends of the tubular member. The outside diameter of the liner opposite ends is then increased to approximately the outside diameter of the tubular member by heating and reforming that portion of the liner opposite ends which extends outwardly from the opposing ends of the tubular member.
