Hot Tapping Machines for Pipeline Applications

Schallert's tapping machine lineup covers a wide range, from the TM100's 3/4-inch to 3-inch taps up to the TM6120's 24-inch to 72-inch capacity. Mid-range machines like the TM200, TM250, TM300, and TM400 fill the gaps between 3 and 48 inches, ensuring a suitable machine for nearly any pipeline diameter.

Electric tapping machines, like the TM100 and TM200, run on 110V power and are ideal for smaller to mid-size taps up to 12 inches, offering convenient setup. Hydraulic machines, such as the TM250 through TM6120, deliver higher torque for larger diameter taps up to 72 inches, requiring a hydraulic power source rated in GPM and psi.

Most Schallert tapping machines and add-on kits are rated for pressures up to 350 psi, making them suitable for pressurized water mains, wastewater lines, and industrial pipelines. Always verify the specific pressure rating of your tapping adapter, cutter, and machine combination before performing a hot tap.

Depending on the model, hot tapping machines typically include boring bars, hole saws, pilot drills, tapping adapters, and a carrying case. For example, the TM100 base kit includes a Milwaukee Hole Hawg adapter, NPT adapters, and a full set of hole saws and pilot drills for taps up to 3 inches.

Stroke length determines how far the boring bar and cutter travel into the pipeline, and it must accommodate the pipe diameter plus valve and fitting clearance. Machines like the TM250 offer 28-inch or 42-inch strokes, while the TM6120 offers 84-inch or 120-inch strokes for large diameter, extended-reach applications.

Yes, Schallert's tapping machines and accessories, including the TM100 6-inch add-on kit, are compatible with most pipeline materials such as ductile iron, steel, PVC, and concrete-lined pipe. Diamond segment cutters are also available for tapping into concrete-lined pipelines up to 72 inches in diameter.
