Technical Examples

A tubular patch expansion apparatus includes an elongated tubular bladder adapted to expand radially outwardly to expand an overlying tubular patch. A bladder setting assembly is secured to a first end of the bladder. The bladder setting assembly has a piston which divides an interior bore into a gas generator chamber and a liquid chamber. Once ignited, gas generating medium generates gas, which causes the piston to move along the interior bore injecting liquid from the liquid chamber into the bladder to inflate the bladder. A liquid pressure relief assembly is provided to relieve pressure within the bladder by releasing liquid from the bladder to allow the bladder to collapse, when the pressure in the bladder reaches predetermined levels.
