Abstract
The present invention provides a hot tap machine having independent speed drives for the center drill and the holesaw that can be remotely operated. The hot tap machine of the present invention also has improved vibratory damping and coupon stability and retention. During operation, the machine cartridge holding the machine internal assemblies of the hot tap machine of the present invention is, except for its controls and external support systems, entirely contained within its pressure containment housing which is sealingly attached to the hot tap fitting on the pipe. An advantage in the operation of the present invention is the independence of the center drilling operation and the pipe coupon cutting operation.
