Water Tapping Machines for Pipeline and Water Service

Tapping machines vary by drive type (electric or hydraulic), tap size range, and stroke length. Small electric units like the TM100 handle taps up to 3", while hydraulic models like the TM250, TM300, TM400, and TM6120 scale up to 14", 30", 48", and 72" respectively, matching different pipeline diameters and pressure demands.

Pricing for hot tapping machines varies based on tap size capacity, drive type, stroke length, and included accessories such as cutter holders, boring bars, and adapters. Because configurations are often customized to specific pipeline diameters and applications, Schallert Enterprises provides pricing on request after reviewing your project requirements.

Electric tapping machines, like the TM100 and TM200, run on standard 110V power and suit smaller taps up to 12", offering portability for field crews. Hydraulic machines require a hydraulic power source (measured in GPM and psi) and are built for larger, higher-torque taps ranging from 14" up to 72" in diameter.

Schallert's tapping machine lineup covers a wide range, from 3/4" service connections using the TM100 up to 72" large diameter mains with the TM6120. Boring bar diameter, stroke length, and drive type are matched to each tap size to ensure clean, accurate cuts under pressure.

Yes, hot tapping is specifically designed to cut into pressurized pipelines without interrupting flow or service. All Schallert tapping machines are rated for pressures up to 350 psi, allowing municipal water utilities and pipeline operators to perform maintenance, repairs, and new connections while the line stays in operation.

A complete hot tapping setup typically includes a tapping machine, boring bar, pilot drill, hole saw or cutter, cutter holder, tapping adapter or valve, and depth measuring rods. Add-on kits, such as the TM100 6" kit, expand a base machine's capability to handle larger tap sizes.
