发明名称 VARIABLE ANGULAR INSERTION METHOD FOR LINING TUBULAR MEMBERS
摘要 A method 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. A series of downsizing rollers (37, 57, 59, 61, 63) reduce the outside diameter of the liner a preselected amount. A series of shaping rollers (65, 84, 85) from the downsized liner into an ellipse, thereby allowing the downsized liner to be guided around bends and turns into the interior of the tubular member. After insertion, the liner is allowed to expand to substantially its original outside diameter to secure the liner within the tubular member.
