KD Pneumatic High-Speed Tube Squaring Machine
Compact ID-mounted tube squarer engineered for heat-exchanger and pressure- vessel manufacturing — where thousands of tube ends must be faced, chamfered and de-burred in a single shift. Pneumatic one-touch clamping, 59 mm head width fits into densely-packed tube sheets.

Why pneumatic one-touch clamping matters on tube sheets
A typical shell-and-tube exchanger has several hundred to several thousand tube ends penetrating each tube sheet, spaced on a triangular or square pitch as tight as 1.25 × OD. Conventional thread-clamp tube facers take 20 – 40 seconds per tube to mount, square, and dismount; on a 2000-tube bundle that becomes 11 – 22 hours of setup time alone. The KD's one-touch pneumatic mandrel engages in under a second per tube — the same operation completed in 30 – 60 minutes. The narrow head (≤ 59 mm) accepts the tightest TEMA pitch without fouling adjacent tubes.
Built for the job site.
Where this series earns its keep.
Heat-exchanger tube-bundle manufacturing
New-build shell-and-tube exchanger fabrication — rapid squaring and chamfering of bundle tube ends to unified protrusion length. The single defining application.
Boiler & condenser re-tubing
In-service exchanger and condenser re-tubing during planned outages, where the narrow head accesses tube sheets that a chuck-type facer cannot reach.
Refinery exchanger maintenance
On-site re-tube and tube-end repair on refinery process exchangers and fired-heater coils during turnaround windows.
