ABSTRACT:
A process for porting air inflated flexible resin impregnated cured in place liner by pulling without loss of pressure is provided. A selectively openable bulkhead fitting is installed at the pull-in end. The filling may be installed in the end of a pull-in liner; on a porting sleeve or secured to an inflated pulled in or inverted liner. A port is formed through the bulkhead fitting by cutting a hole through the valve assembly. A steam fitting with an exhaust hose is coupled to the bulkhead fitting while maintaining pressure in the inflation bladder. Steam for curing the resin is then introduced into the inversion apparatus to cure the resin and is exhausted through the exhaust hose.
