Internal Expansion Pneumatic Pipe Beveling Machine

This portable tool securely mounts onto the outside (OD) of pipes using powerful adjustable clamps, enabling precise on-site cutting and beveling without internal mandrels. Its rotating cutting head, driven by a hydraulic or electric motor, orbits around the pipe to deliver clean, square cuts and consistent bevel angles (e.g., 30°-37.5° for welding prep). Designed for field use, it handles carbon steel, stainless steel, and alloy pipes in demanding sectors like oil & gas, shipbuilding, and pipeline construction. This solution eliminates workshop transport, saving time and costs while ensuring weld-ready pipe ends in tight or remote locations.

Overview of Lsp internal expansion pneumatic pipe beveling machine:

This series of machines is driven by air motors and is mainly suitable for explosive and fireproof places. It can work with 0.6-0.8MPa air source. There is a scale on the feed handwheel, and the cutter can be installed at any angle. It has the characteristics of fast tightening, automatic positioning, easy installation, safe and reliable use.

Main performance of Lsp internal expansion pneumatic pipe beveling machine:

This series of machines adopts air motor drive, bevel gear transmission, and three-stage planetary gear reducer deceleration; it is suitable for explosive, fire-proof and other dangerous workplaces. Good rigidity, high precision, easy and simple operation, safe and reliable use.

Features of Lsp internal expansion pneumatic pipe beveling machine:

  1. It can process carbon steel, stainless steel, alloy steel and other pipes,
  2. Completely cold processing, does not affect pipe processing at all,
  3. High processing efficiency, cutting and beveling operations can be completed synchronously in one clamping,
  4. High-precision, high-quality processing, accurate size, high finish, and the processed end face is perpendicular to the axis of the steel pipe,
  5. It can be equipped with a boring tool holder for pipe internal beveling or boring processing.

Main performance of Lsp internal expansion pneumatic pipe beveling machine:

This machine can meet the beveling processing of large diameter and thick wall pipes, and has a wide range of applications. It can not only bevel the U and V-shaped welds of the pipe, but also process the convex flange and flat flange after welding. There is an angle scale on the tool holder, which can select any angle, and it is equipped with an automatic tool feeding function, which is simple and convenient to operate.

Structural features of Lsp internal expansion pneumatic pipe beveling machine:

  1. Small radial net space, light weight, suitable for places with complex environment and small space
  2. It can be installed in half. This structure is suitable for situations where there are non-removable or non-removable objects at both ends of the pipe.
  3. One-time clamping can complete cutting and beveling processing at the same time.

Frequently Asked Questions – Pipe Cutting Beveling Machine

Yes, our machines feature heavy-duty carbide cutters designed to penetrate surface scale/coatings. For best results:

  • Use coated-surface-specific cutter blades (optional).

  • Secure clamps on clean pipe sections if possible.
    (Highlights robustness & solution for real-world site conditions)

Standard models cover 2″ to 48″ (DN50-DN1200) OD.

  • Key: Select the correct clamp adapter kit for your pipe size.

  • Custom solutions available for sizes beyond this range.

±0.5° tolerance guaranteed with calibrated machines.

  • Hydraulic: Ideal for high-torque demands (thick-walled/stainless pipes).

  • Electric: Best for clean/indoor sites – quieter & no hoses.

  • Portability: Battery-powered models available.

Blade life varies by material:

  • Carbon steel: 150-200 cuts (12mm wall thickness).

  • Stainless/duplex: 50-80 cuts (recommend coolant).

  • Extend life: Reduce feed rate, use lubricant, inspect for chipping.
