Method of installing liner assembly for pipeline repair or reinforcement, and liner assembly and steam generator for same

An automated steam generator system for use with a liner assembly for a pipeline section, the system comprising:

• a steam generator configured to flow a steam-air mixture continuously through a bladder of the liner assembly inflated within the pipeline, the bladder being positioned within a tubular liner wetted with a curable compound, the steam generator comprising:
• a temperature sensor measuring a temperature of the steam-air mixture entering the bladder, and
• a flow rate meter measuring a flow rate of the of the steam-air mixture entering the bladder;
• and
• a computing device in communication with the steam generator and comprising:
• processing structure, and memory in communication with the processing structure and storing computer-readable code comprising instructions which, when executed by the processing structure, cause the computing device to:
• calculate a time period sufficient for the tubular liner to cure based on:
• an amount of total heat required for curing, based on dimensional information of the tubular liner, and
• the measured flow rate and the measured temperature of the steam-air mixture;
• and
• control the steam generator to flow the steam-air mixture through the bladder for the time period sufficient for the tubular liner to cure.
