External Clamp Split Frame Pipe Beveling Machine

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
