Split Frame Clamshell Pipe Cutter Demo

This demonstration shows the Split Frame Series external clamp clamshell machine performing in-line cold cutting and beveling on pipe that stays in position — no end access, no torch, and no hot-work permit required.

What the Video Shows

The split-frame design is what makes on-site work possible: the machine separates into two halves that bolt together around a pipe already welded into a line. Once clamped, the ring rotates tool bits around the pipe circumference, parting the pipe and machining the weld bevel in the same setup. Because this is cold machining rather than flame or plasma cutting, there is no heat-affected zone and the finished bevel is ready for welding without grinding.

Series Capabilities

• Pipe OD range: 25-1230mm across 20 sizes
• Wall thickness: up to 35mm electric / pneumatic, up to 150mm hydraulic
• Drive options: electric, pneumatic or hydraulic
• Operations: simultaneous cutting and beveling with V, compound, or J profiles

Typical Applications

Split frame clamshells are the standard tool for pipeline maintenance and tie-ins, offshore platform and subsea spool work, power plant retrofits, and any job where a section must be cut out of an existing line and re-welded in place. Pneumatic and hydraulic drive options allow operation in explosion-risk environments where electric tools are prohibited.
