Method of installing liner assembly for pipeline repair or reinforcement, and liner assembly and steam generator for same
A method of installing a liner assembly for pipeline repair or reinforcement includes: pulling a prepared liner assembly into position in the pipeline, the liner assembly including a tubular liner wetted with a curable compound; introducing fluid into the inflatable bladder to bring the tubular liner into firm contact with an interior surface of the pipeline; flowing the fluid continuously through the bladder and discharging the fluid into the pipeline, while maintaining the liner assembly in an inflated condition; measuring a flow rate and a temperature of the fluid entering the bladder; calculating a time period sufficient for the tubular liner to cure based on: an amount of heat required for curing, based on dimensional information of the liner, and the measured flow rate and temperature of the fluid; and maintaining the liner assembly in an inflated condition for the time period sufficient for the tubular liner to cure.
