Abstract
There is described a novel tool and method for the isolation and pressure-testing of connections, such as welds, between a vessel and a nozzle or branch pipe. The nozzle testing tool comprises an improved seal that expands into sealing contact as testing pressure is increased. The tool can also be easily adjusted in order to accommodate variations in nozzle configuration.
