SE-4PTD

Overview

The BUG-O SE-4PTD is a programmable pass-through pipe cutting machine designed for cutting saddles, offset saddles, laterals, miter cuts, holes and customized shapes in pipe. It is a computer-controlled system that reduces the need for templates, manual layouts and complex calculations, allowing operators to produce repeatable pipe profiles more efficiently.

The SE-4PTD provides dual programming capabilities. A dedicated pipe program is used for standard pipe cuts such as saddle cuts, offset or hillside cuts, laterals, miters and holes. A second selectable shape program allows customized pipe shapes to be programmed and cut when the job requires non-standard geometry.

The machine is designed for pass-through cutting of pipe from 4″ to 12 3/4″ O.D. / 100 to 325 mm. It can also internally chuck short pipe lengths up to 20″ / 500 mm diameter. The SE-4PTD can be configured for plasma cutting, oxy-fuel cutting or both, making it a flexible pipe cutting solution for fabrication shops, industrial pipework, maintenance departments and production environments.

Technical advantages

The main technical advantage of the BUG-O SE-4PTD is its combination of programmable pipe cutting and large pass-through capacity. It allows pipe from 4″ to 12 3/4″ O.D. to pass through the machine, while short pipe lengths can be internally chucked up to 20″ diameter. This makes the machine more capable than smaller pass-through systems where larger pipe access is required.

The dual programming system improves production efficiency. The pipe program covers common fabrication cuts such as saddles, offset or hillside cuts, laterals, miters and holes. The shape program allows the user to cut customized arbitrary shapes in pipe, making the SE-4PTD suitable for both standard work and more specialized pipe geometry.

Two axes of the machine work together to provide a constant torch travel speed. This is important because cutting speed depends on the cut shape and the pipe size. Coordinated motion helps produce more controlled and repeatable cuts than manual torch movement or template-based freehand cutting.

The SE-4PTD is also process-flexible. When configured for plasma cutting, the machine uses ground brushes, a ground ring and a contact relay to turn the plasma torch on and off automatically. When configured for oxy-fuel cutting, the machine uses a solenoid-controlled oxy-fuel manifold to turn cutting oxygen on and off automatically.

The pass-through design requires correct pipe support alignment behind the machine. When properly supported, the machine can handle pipe weight up to 375 lb / 170 kg, making it suitable for heavier pipe sections within its stated working range.

Applications

The BUG-O SE-4PTD is designed for pipe fabrication operations where repeatable pipe profiles, branch openings and custom pipe shapes are required. It is suitable for saddle cuts, offset saddle cuts, hillside cuts, lateral cuts, miter cuts, hole cuts and arbitrary custom shapes.

Typical applications include industrial pipe fabrication, process piping, branch connection preparation, nozzle preparation, structural pipework, pipe-to-pipe fit-up, maintenance work, fabrication workshops and production environments where template-free programmable cutting improves accuracy and workflow.

The SE-4PTD is especially useful where larger pass-through pipe capacity is needed. Its ability to pass pipe up to 12 3/4″ O.D. through the machine, combined with internal chucking of short pipe lengths up to 20″, gives fabrication teams more flexibility than smaller pass-through pipe cutters.

Why choose this product

The SE-4PTD is a strong choice for companies that need programmable pipe cutting with larger pass-through capacity. It reduces reliance on manual templates and layout work, helping operators produce standard and custom pipe cuts with better repeatability.

For fabrication teams, the value is practical and measurable: faster setup, fewer manual calculations, more consistent cut geometry and improved repeat production. The pipe program supports common fabrication cuts, while the shape program gives the machine additional flexibility for non-standard work.

The ability to configure the machine for plasma, oxy-fuel or both also increases its commercial usefulness. Buyers can select the cutting process that best matches their material, thickness, existing equipment and production requirements.
