Portable Tapping Machines

Portable tapping machines in our lineup handle a wide range of tap sizes, from 3/4 inch up to 72 inches in diameter. Smaller electric models like the TM100 and TM200 cover 3/4 to 12 inches, while larger hydraulic models like the TM400 and TM6120 extend coverage up to 48 and 72 inches respectively.

Hot tapping is the process of drilling into a pressurized pipeline to create a new connection or service tap without shutting down or depressurizing the system. It's widely used in municipal water infrastructure and industrial pipelines to minimize service disruption, reduce downtime, and avoid the costs associated with system shutdowns.

Power requirements vary by machine size. Smaller hydraulic models like the TM250 require 8 GPM at 2200 psi, mid-size units like the TM300 need 16 GPM at 2000 psi, and the largest machines such as the TM6120 require 21 GPM at 1500 psi. Matching your hydraulic power unit to the machine's specifications ensures proper operation.

Yes, these machines are specifically designed for hot tapping water mains and other pressurized lines without interrupting flow. This capability is essential for municipal water utilities and pipeline service companies performing maintenance, repairs, or new service connections while keeping the system operational.

Boring bar diameter should match your tap size and cutting depth requirements. Smaller taps under 14 inches typically use a 2.0 to 2.5 inch boring bar, mid-range taps from 12 to 48 inches use 3.0 to 4.0 inch bars, and the largest 24 to 72 inch taps require a 6.0 inch boring bar for stability and cutting performance.

Yes, all Schallert Enterprises tapping machines, including hydraulic and electric models, are manufactured in the USA. This ensures consistent quality control, durability, and support, with equipment built to withstand decades of demanding hot tapping and pipeline service applications.
