ABSTRACT:
The powered pipe cutter and the pipe flaring tool both have a piston slidably mounted in a cylinder. The cylinder has a top end closed by a top end plug. A crimped cartridge bore in the top end plug communicates with a gas expansion chamber. A bolt and firing pin assembly are attached to the cylinder top end. The pipe cutter includes a shear housing with a pipe passage connected to the rod end of the cylinder. A shear plate is connected to the piston and moves with the piston to shear pipes. The pipe flaring tool includes a pipe clamp assembly with a pipe passage and a female flaring surface connected to the cylinder rod end. A male flaring surface on the piston cooperates with the female flaring surface to flare pipe ends.
