Zusammenfassung:	A PROCESS FOR PORTING AIR INFLATED FLEXIBLE RESIN IMPREGNATED CURED IN PLACE LINER (16,206) BY PULLING WITHOUT LOSS OF PRESSURE IS PROVIDED. A SELECTIVELY OPENABLE BULKHEAD FITTING (31,118, 201) IS INSTALLED AT THE PULL-IN END. THE FITTING (31,118, 201) MAY BE INSTALLED IN THE END OF A PULL-IN LINER (16, 206); ON A PORTING SLEEVE(117) OR SECURED TO AN INFLATED PULLED IN OR INVERTED LINER (16, 206). A PORT IS FORMED THROUGH THE BULKHEAD FITTING (31,118, 201) BY CUTTING A HOLE THROUGH THE VALVE ASSEMBLY (71). A STEAM FITTING WITH AN EXHAUST HOSE (61) IS COUPLED TO THE BULKHEAD FITTING (31,118, 201) WHILE MAINTAINING PRESSURE IN THE INFLATION BLADDER (56). STEAM FOR CURING THE RESIN IS THEN INTRODUCED INTO THE INVERSION APPARATUS (46) TO CURE THE RESIN AND IS EXHAUSTED THROUGH THE EXHAUST HOSE (61).
