Internal Expansion Pipeline Beveling Machine
The internal expansion pipeline beveling machine uses mandrel expansion clamping technology to securely grip pipe ID while creating precise weld preparation bevels. Designed for field pipeline construction and shop fabrication, this ID mounted beveling tool processes pipe sizes from DN50 to DN600 with wall thicknesses up to 50mm.
Perfect for oil & gas pipelines, power plant piping, shipbuilding and structural steel fabrication where access to pipe exterior is limited or rotating the pipe is impractical.Get a Free Quote
Advantages of Internal Expansion Design
No external pipe support required - ideal for in-ditch pipeline work
Self-centering eliminates alignment adjustments
Secure clamping prevents pipe movement during heavy cuts
Processes in-service pipelines without rotation
Compact design accesses tight pipe rack locations
Suitable for carbon steel, stainless, alloy and thin-wall pipe
For precision welding preparation, internal type machines provide more stable results.
Why Choose an Internal Expansion Type Pipe Beveling Machine?
Unlike external clamp beveling machines, this model expands from inside the pipe, ensuring:
Higher concentric accuracy
Stable cutting performance
Minimal vibration
Suitable for narrow or limited working space
Ideal for fixed pipeline systems
Applications & Industries
This portable internal pipe beveling machine is compact and easy to transport. It is particularly effective in:
Oil & Gas Pipeline Construction: Field girth weld preparation
Power Plant Piping: Boiler feedwater, steam lines, turbine piping
Shipbuilding: Engine room piping systems
Petrochemical: Process piping, high-pressure lines
Nuclear Power: Safety-related piping systems
Structural Steel: Heavy wall pipe fabrication
Its modular structure allows fast assembly and safe operation even in confined environments.
FAQ
Q1: What pipe materials can this machine process?
A: Carbon steel, stainless steel, alloy steel, duplex stainless. Not recommended for titanium or high-nickel alloys.
Q2: Minimum pipe ID clearance required?
A: Mandrel requires 25mm clearance beyond cut depth for chip evacuation.
Q3: Can it bevel thin wall pipe (Sch10)?
A: Yes, special thin-wall mandrels available for 3-6mm wall thickness.
Q4: Power requirements for field operation?
A: 220V single phase or 380V 3-phase. Pneumatic models require 0.6-0.8MPa clean air.
