Internal Expansion Pipe Beveling Machine - II Model

Overview

The ISE II-Model Series is our heavy-duty lineup of ID-mounted beveling machines, purpose-built for thick-wall pipe applications where standard machines fall short. With wall thickness capacity up to 75mm, these machines serve the most demanding sectors: nuclear power, high-pressure vessels, and offshore oil & gas.

Key Advantages

• 75mm wall capacity - Handles extreme wall thicknesses for critical applications
• Angled motor design - Superior torque transfer for heavy cutting loads
• Robust clamping - Heavy-duty expansion mechanism for secure grip
• Cold machining - No heat-affected zone preserves material properties

T-Model vs II-Model Comparison

Specification	T-Model	II-Model
Max Wall Thickness	≤15mm	≤75mm
Motor Configuration	Vertical (T)	Angled (Y)
Torque Capacity	Standard	Heavy-duty
Weight Class	3.5-45kg	18-60kg
Best For	Standard pipes	Thick-wall, critical welds

Which Model Should You Choose?

For medium pressure vessels and headers (80-240mm ID):
The ISE-252-2 is the entry point into heavy-wall beveling. Perfect for fabricators transitioning from T-Model work to thicker applications. Most pressure vessel shops start here.

For high-pressure piping and nozzles (150-330mm ID):
Choose the ISE-352-2—our most popular II-Model. It handles the sweet spot of pressure vessel nozzle work and thick-wall headers. If you only buy one II-Model, this is the one.

For large headers and thick-wall process piping (250-426mm ID):
The ISE-426-2 serves heavy industrial sectors: offshore platforms, LNG terminals, and major refinery projects where 300-400mm heavy-wall pipes are routine.

For major pressure vessels and nuclear (300-830mm ID):
Our ISE-630-2 and ISE-850-2 are purpose-built for the most demanding applications—nuclear power components, high-pressure steam drums, and subsea equipment where wall thickness and weld quality are critical.

Drive Options

Drive Code	Type	Best For
ISOE	Electric	General heavy-duty workshop use
ISOP	Pneumatic	Hazardous areas, offshore platforms
ISOM	Metabo	Premium quality, continuous operation

Heavy-Wall Bevel Profiles

For walls over 20mm, weld joint design becomes critical. The II-Model produces:

• V-Type Bevel - Standard 30°, 37.5°, 45° included angles
• Compound Bevel - Root face (land) + bevel angle for controlled penetration
• J-Prep (U-Type) - Radiused root with straight bevel, reduces weld volume
• Double-J - Symmetric J-prep on both ends for minimum weld volume

Customization Options

• Bevel Angle — Standard angles (30°, 37.5°, 45°), J-prep and compound bevels available
• Drive System — Electric (ISOE), pneumatic (ISOP), or Metabo (ISOM) options
• Voltage — 220V/380V AC standard, other configurations available
• Tooling — Torque-limiting feed handle and specialty cutter sets available
