ABSTRACT:
A pressure testing apparatus is provided for internally pressure testing pipe. A mandrel is secured to a frame and is adapted to receive a pipe thereon such that a gap exists between an outer surface of the mandrel and an inner surface of the pipe. A first end cap is disposed on an outer surface proximal a first end of the mandrel. A second end cap is connected to a second end of the mandrel. First and second seal members are disposed between the first and second end caps and the first and second pipe ends, respectively, such that the first and second seal members abut respective ends of the pipe disposed on the mandrel. A line is in fluid communication with the gap to fill the gap with a testing fluid.
