Is your team still burning pipes or grinding by hand? Stop wasting time and money on old methods.
You know the problem. Your workers are on a construction site or inside a tight factory. They need to weld two pipes together. But the pipe ends are not ready. They use a gas torch to cut the bevel. This makes the metal too hot. The pipe warps. The cut is rough and uneven. Then, they have to spend hours grinding the edge to make it smooth. This is slow. It is hard work. It ruins the metal quality. And it is dangerous to use fire in tight spaces.You need a better way. You need a tool that cuts clean, cuts fast, and is safe to use. You need the Internal Expansion Electric Pipe Beveling Machine. It solves all these headaches. It uses a cold-cutting method. This means the metal stays cool. The structure does not change. The surface is smooth and ready for welding. No grinding needed. It is light. One person can carry it. It fits inside the pipe and centers itself automatically. This is the modern solution for pipe installation, maintenance, and fabrication.
What makes this machine the best choice for your business?
This is not just a simple cutter. It is a smart tool designed for real work. The core design is the internal expansion (or internal mounting) system. Imagine a claw that goes inside the pipe. It expands to grip the inner wall. This does two big things for you.First, it centers the tool perfectly. You do not need to measure or guess. The machine finds the center of the pipe automatically. This ensures the bevel is even all the way around. Second, it holds the tool tight. Even when cutting thick steel, the machine does not shake or slip.The drive system is powerful. We use a high-performance electric motor with a planetary gear reducer. This gives the machine high torque (twisting force) even at low speed. The cutter head spins steadily. It does not bog down in hard metal like stainless steel or alloy steel.We offer two main drive types to fit your needs:
- Electric Drive: Uses a standard 220V power supply. It is great for most indoor or outdoor sites with electricity. It is quiet and has strong power.
- Pneumatic Drive: Uses compressed air. It is perfect for explosive environments like oil refineries or gas lines. It is explosion-proof and safe.
This machine is a portable pipe beveler. You can take it anywhere. It is also a flat plate chamfering machine. With a simple change, you can use it on steel plates, not just round pipes. It handles V-type, U-type, J-type, and compound bevels. You can adjust the angle from 0 to 45 degrees easily.
See the technical power behind the cuts
We build these machines for heavy industry. They are tough. They last a long time. Here are the real specs you need to know. We have different models for different pipe sizes.
Model ISY-150 / ISY-250 Series Specifications
These are our most popular models for on-site work. They cover a wide range of pipe diameters.
| Feature | Specification |
|---|---|
| Power Supply | AC 220V, 50-60Hz (Single Phase) |
| Motor Power | 1200W to 1800W (Strong cutting force) |
| Pipe Range (Internal) | 65mm to 240mm (2.5 to 9.4 inches) |
| Wall Thickness | Up to 20mm (0.8 inches) |
| Cutting Speed | 20 to 34 RPM (Slow and steady for clean cuts) |
| Bevel Angle | 0°, 15°, 30°, 37°, 45° (Adjustable) |
| Feed Mode | Manual hand wheel or Automatic feed |
| Machine Weight | 30kg to 60kg (Easy to lift and carry) |
| Cutter Head Speed | 34 RPM (Optimized for steel) |
Heavy Duty Models for Large Projects
If you work on big pipelines or structural projects, look at our large models like ISY-630 or the SDD/HDD series.
- Pipe Diameter: Can handle pipes from 280mm up to 1470mm (11 to 58 inches).
- Wall Thickness: Can cut walls up to 120mm thick in special heavy-duty versions.
- Drive: Uses 380V 3-phase power or hydraulic power for massive torque.
- Control: Some models offer CNC or PLC control for automatic walking and precise depth cuts.
All machines use cold cutting technology. There is no heat-affected zone (HAZ). The metal grain structure stays the same. This is critical for food industry, pharmaceutical, and nuclear pipes where purity and strength matter.
Where can you use this machine in your daily work?
This tool is versatile. It fits into many jobs. Our customers use it in these specific scenarios:
1. Oil, Gas, and Chemical Pipeline Maintenance
This is the #1 use case. When a pipe leaks or needs replacement in the field, you cannot move it to a workshop. You bring this portable beveling machine to the site. The internal expansion design is perfect for fixed pipes. You slide it into the open end, expand it, and start cutting. It works on carbon steel and stainless steel pipelines. It is safe because it does not create sparks like a grinding wheel.
2. Shipbuilding and Marine Engineering
Ships have miles of piping. Space is tight. Weight matters. This machine is light (around 30-50kg). A worker can carry it up a ladder or into the hull. It is used for beveling pipes for HVAC, fuel lines, and hydraulic systems. It is also used on steel plates for hull repairs.
3. Boiler and Pressure Vessel Fabrication
In boiler making, the pipe walls are thick. You need a deep U-groove or J-groove for strong welds. Our heavy-duty models with automatic feed can handle this. They cut deep, smooth grooves without stopping. This ensures the boiler can handle high pressure safely.
4. Construction and Steel Structure
For handrails, stadium structures, and bridges, you need to bevel the ends of steel tubes before welding. This machine acts as a pipe end facing machine. It makes the end flat (0 degrees) or angled (V-type) perfectly. It is much faster than a manual milling machine.
5. Food, Pharmacy, and Water Treatment
These industries need perfectly smooth welds. Bacteria cannot hide in a smooth weld. The automatic pipe beveler creates a mirror-like finish. It does not contaminate the pipe with heat or sparks. It is ideal for sanitary piping systems.
Easy to use and easy to keep running
You do not need a PhD to operate this. The setup is simple.
- Clean the pipe: Make sure the inside is clean.
- Insert the machine: Slide the cutter head into the pipe.
- Expand: Turn the handle or switch to expand the gripping shoes. The machine centers itself.
- Lock: Tighten the locking nut to secure it.
- Cut: Turn on the motor. Adjust the tool post for the angle. Start the feed.
Maintenance is also simple. The cutter blades are reversible. When one side gets dull, you flip it or rotate it. You only need to change the blade after a long time. The gearbox needs grease every few months, just like a drill. We provide spare parts like cutter blades, expansion shoes, and carbon brushes for the motor.We also offer OEM/ODM services. If you need a specific color, a different voltage (like 110V or 440V), or a custom logo, we can do it. We are a factory and a trading company. We control the quality from the raw material to the shipping box.
