KEPUNI Planetary Pipe Cutting Machine: High-Precision Preparation for Flawless Welding

Introduction

KEPUNI provides professional planetary pipe cutting machine to assist pipe welding operations.

  • The cutting and beveling are completed by rotating the tool under the static condition of the pipeline;
  • Pipe diameter adjustment is fast and it can be completed within a few seconds;
  • The pipe is automatically centered during cutting and the groove is uniform;
  • The cold working process will not damage the pipe material, fast cutting and high efficiency;
  • The incision is not deformed, the end face is free of burrs and keep clean and it is very suitable for occasions requiring high-quality welding;

Essential Details

KEPUNI’s planetary pipe cutting machine is engineered to streamline pipe welding operations by delivering precise, cold-cutting solutions that preserve material integrity. Unlike conventional methods, this system rotates the cutting tool around a stationary pipeline, ensuring uniform beveling and groove quality without compromising structural strength.

Key Features:

1.Rapid Diameter Adjustment
Equipped with a quick-change mechanism, the machine adapts to pipe diameters ranging from 15 mm to 600 mm (adjustable within seconds), eliminating the need for manual tooling swaps.

2.Auto-Centering for Consistent Accuracy
A self-centering chuck automatically aligns the pipe during cutting, guaranteeing a ±0.1 mm concentricity tolerance and uniform groove geometry across the entire circumference.

3.Cold-Cutting Technology for Material Protection
The friction-based cutting process generates minimal heat, preventing work hardening, deformation, or material degradation. This cold-working method ensures the pipe’s mechanical properties remain intact for high-pressure or critical applications.

4.Burr-Free, High-Quality Finishes
Produces clean, square cuts with zero edge deformation and burr-free end faces, meeting stringent ASME B31.3 and ISO 15614-1 standards for welding preparation.

5.Efficiency and Versatility
 processes materials including carbon steel, stainless steel, duplex alloys, and copper-nickel, making it ideal for oil/gas pipelines, power plants, and shipbuilding.

Applications:

Pressure Vessel Fabrication: Prepares welded joints for ASME Section VIII certification.

Offshore Platforms: Ensures corrosion-resistant welds in harsh marine environments.

Nuclear Power Plants: Complies with RCC-MR codes for reactor piping systems.
