Method of lining a host pipe with a liner using cryogenic cooling |
摘要 |
A method and apparatus for lining a host pipe with an elastomeric liner having an outside diameter which is initially greater than the inside diameter of the host pipe. A length of the liner is reduced to a downsized outside diameter and the downsized liner is cryogenically cooled to a supercooled state to maintain the downsized dimensions of the liner while increasing the tensile strength to facilitate insertion of the liner into the host pipe.
