See the Split Frame Clamshell cutter in action for on-site pipe cutting and beveling
Overview
The Split Frame Series is our heavy-duty solution for in-line pipeline cutting and beveling. Unlike machines that slide over pipe ends, the split-frame clamshell design wraps around the pipe at any point along its length. This capability is essential for pipeline maintenance, tie-ins, and offshore operations where pipes are fixed in place and end access is impossible.
Key Advantages
- In-line mounting - Clamps anywhere on pipe, no end access needed
- 110mm wall capacity - Handles the thickest walls with hydraulic drive
- Four drive options - Match power source to environment and wall thickness
- Field portable - Breaks down for transport to remote locations
Why Split Frame?
Most pipe beveling machines need access to the pipe end—they slide on like a ring. But real-world pipelines are buried underground, suspended offshore, connected at both ends, or impossible to move. Split frame opens like a clamshell, wraps around the pipe, and gets the job done.
Size Groups
| Group | OD Range | Models | Typical Application |
|---|---|---|---|
| Small | 89-325mm | OCE-168 to OCE-325 | Process piping, distribution |
| Medium | 377-630mm | OCE-377 to OCE-630 | Transmission lines, headers |
| Large | 715-1066mm | OCH-715 to OCH-1066 | Main trunk lines, risers |
| Extra Large | 1230-1830mm | OCE/OCH-1230 to 1830 | Major pipelines, penstocks |
Drive Selection Guide
| Drive | Code | Wall Capacity | Best For |
