Galvanized Steel Interlocked Oval Pipe Roll Forming Machine

If you need to mass-produce thin-walled oval pipes for electric conduits or wiring ducting, our Interlocked Oval Pipe Roll Forming Machine is engineered for precision and efficiency. Leveraging the roll forming principle, it creates interlocked oval tubes (no welding required for thin materials) and integrates key functions like necking for easy tube connection—ideal for projects demanding reliable, seamless pipe structures.

The interlocked oval pipes produced by this machine are primarily used in electrical systems, serving two critical roles:

• Electric Conduits: Protect electrical wires from external damage (e.g., impact, moisture) with a closed, interlocked structure that ensures long-term safety.
• Electric Wiring Ducts: Organize and route wiring in industrial or commercial settings, leveraging the oval shape for space-saving installation and easy access.

We’ve prepared detailed drawing profiles of the oval tubes for your reference—contact us to check if the dimensions align with your electrical project needs.

The Interlocked Oval Pipe Roll Forming Machine integrates all components required for end-to-end oval pipe production, ensuring smooth, continuous operation. Its core structure includes:

1. 3TON Manual Decoiler: Unwinds raw material coils (galvanized or prepainted steel) steadily, providing a stable material supply for subsequent steps.
2. Feeding Unit: Controls the speed and alignment of raw material feeding, with manual operation support—allowing easy adjustments when switching between materials of different thicknesses.
3. Cooling System: Prevents overheating of rollers and materials during forming, protecting machine components and ensuring consistent pipe quality.
4. Roll Forming System: The heart of the machine, shaping flat metal sheets into oval profiles via precision rollers, with an interlocked seam (no welding needed for thin materials).
5. Transmission System: Drives the roll forming and feeding units synchronously, maintaining uniform forming speed and avoiding material deformation.
6. Cutting System: Trims finished oval pipes to your desired length, ensuring consistent dimensions for easy installation.
7. Control System: Centralizes operation of all components, simplifying parameter adjustments and ensuring stable production.
8. Run-Out Supporting Rack: Supports finished pipes as they exit the machine, preventing bending or damage during collection.

The machine is optimized for thin-walled materials, with clear guidelines for material selection based on thickness:

• Suitable Materials: Galvanized steel or prepainted steel (corrosion-resistant, ideal for electrical applications).
• Interlock Applicable Thickness: 0.3-1.2mm (for materials within this range, the machine uses bending and folding to create a closed interlocked seam—no welding required, saving cost and time).
• Thickness Beyond 1.2mm: If your project requires thicker materials, we recommend pairing the machine with a welding system (e.g., TIG welding, laser welding, HF welding) or a secondary shaping machine (to convert round tubes to oval tubes)—we can customize the setup to meet this need.

A common question from customers is: “Can one machine make multiple oval pipe sizes?" While a single mold set is limited to one size, we offer a fast-change design to solve this challenge:

• How It Works: Rollers and shafts are mounted on a dedicated base frame. To switch pipe sizes, simply replace the base frame (no need to disassemble or replace shared components like the decoiler, PLC, shearing system, or motor).
• Cost Savings: Reduces investment in duplicate shared components, making multi-size production more economical.
• Flexible Options: We offer both economic and high-quality fast-change designs, tailored to your budget and production frequency of size switches.

To solve the problem of “how to overlap one oval tube with another", we integrate a necking machine into the production line:

• Necking Process: The necking machine reduces the diameter of one tube end (with reinforcing ribs) so it can be inserted into another tube seamlessly.
• Benefit: Creates a tight, secure connection between tubes—no additional fasteners needed, simplifying installation and enhancing structural stability.

We’ve prepared a detailed working video that showcases the full production cycle of the Interlocked Oval Pipe Roll Forming Machine—from decoiling, roll forming, and necking to cutting and tube overlapping.
