Split Frame Clamshell Pipe Cutter & Beveler
The Split Frame Clamshell is a precision OD-mounted pipe cutting and beveling tool designed for in-line maintenance, fabrication, and shutdown operations. Its split-frame design allows the machine to open and clamp securely around the outside diameter of the pipe—eliminating the need to rotate or remove the pipe from service.
Built for cold cutting, beveling, facing, and counterboring, the clamshell delivers weld-ready finishes on pipe sizes ranging from 1″ to 60″ OD. Modular tool slides and interchangeable cutting inserts allow for versatile machining profiles, including single-point cutting and flange facing. Available in pneumatic, hydraulic, or electric drive configurations, the Split Frame Clamshell is trusted across oil & gas, petrochemical, and power generation sectors for its accuracy, durability, and field portability.
