  • Hydraulic punch tool for heat exchangers
    Patent number: 4730392
    Abstract: A punch tool is disclosed for puncturing the walls of heat exchanger tubes when they become worn in order that the tubes may be repaired. Said tool comprises a hardened, longitudinally drilled, steel rod that is able to fit within the heat exchanger tube. A piston with a cutting bit is fit within a milled slot that communicates with the longitudinally drilled hole of the hardened rod. Once the tool is inserted into a tube to be repaired hydraulic pressure is applied and the piston is forced outward thereby puncturing the tube.
