Questions we answer most.

ID-mount bevelers expand inside the bore. They are lighter, faster to set up, and the obvious choice when the pipe end is open and clear. OD-mount (clamshell) machines clamp around the outside and work on pipe that is already installed — close to a wall, in a rack, or where the bore is obstructed. Full comparison in ID vs OD mount pipe bevelers.

Five things decide it: diameter or plate thickness range, wall thickness, material, the bevel geometry your WPS calls for, and whether the work comes to the machine or the machine goes to the work. Send us those five and we will name a model. Or start with the 2026 buying guide.

Yes — stainless, duplex, chrome-moly and Inconel, with the appropriate insert grade. Cold machining matters more on these materials than on carbon steel, because a thermal cut leaves a chromium-depleted zone that has to be ground back before welding. See beveling stainless steel and P91 and chrome-moly.

Stationary machines are faster per cut and more accurate, and they make sense when spools come to a shop. Portable machines win the moment the work cannot move — installed pipe, site repairs, anything already welded into a system. The trade-off in detail.

Roughly 200 – 500 bevels on carbon steel, considerably fewer on stainless or hardened material. The signals are chatter marks, a rougher finish, and rising cutting force. Keep spares on the shelf — an insert change is minutes, waiting for a shipment is days.

Chips and swarf wiped down daily, guide rails and bearings lubricated weekly, gears and drive components inspected monthly, calibration checked periodically. A full schedule ships with every machine; the reasoning behind it is in the maintenance guide.

Nine times out of ten it is a dull insert or uneven clamping. Check the machine is seated square to the pipe face and the clamping force is even all round. Chatter marks mean reduce feed rate; a rough finish usually means the wrong insert grade for the material.

A bevel protractor or gauge against the machined face, checked at several points around the circumference — a single reading will not catch a machine that is sitting out of square. Method and tolerances in how to measure bevel angles.

Video walkthroughs ship with every machine, and we arrange remote or on-site sessions on request. Most operators are comfortable after a day of hands-on practice — the harder part is usually persuading an experienced welder to change a method that has worked for twenty years.

12 months on manufacturing defects in materials and workmanship under normal use. Wear parts — inserts, clamping jaws, seals — are covered for 3 months. Misuse and unauthorised modification are not covered. Extended options are available.

Common wear parts are held in stock and normally leave Shenzhen within 24 – 48 hours. Expedited shipping is available for line-down situations. If a machine is critical to your schedule, keep a basic spare kit on site.

Routinely. Bevel angles, clamping ranges and tool configurations are modified for specific projects; unusual pipe sizes, special materials and non-standard working conditions are normal enquiries rather than exceptions. Send the drawing.

One unit. We sell to individual contractors and crews, not only to bulk buyers. Volume pricing and OEM/ODM branding start to apply on multi-unit orders.

We do not run a rental fleet ourselves, but several equipment rental companies stock our machines. Ask and we will point you at one in your region.

Ranges by machine type, and what moves a machine inside its band, are set out on the cost guide. For a figure against your actual specification, send a request — we reply within 24 hours.
