Galvanized Steel Interlocked Oval Pipe Roll Forming Machine
Specialized for Electric Conduits & Wiring Ducts
Our Interlocked Oval Pipe Roll Forming Machine is engineered for precision and efficiency in mass-producing thin-walled oval pipes for electric conduits or wiring ducting. Using 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.
Core Application: Oval Pipes for Electric Conduits & Wiring Ducts
The interlocked oval pipes produced by this machine serve two critical roles in electrical systems:
- 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.
Full Machine Configuration: From Decoiling to Finished Pipe
The Interlocked Oval Pipe Roll Forming Machine integrates all components required for end-to-end oval pipe production:
- 3TON Manual Decoiler: Unwinds raw material coils (galvanized or prepainted steel) steadily, providing a stable material supply.
- Feeding Unit: Controls the speed and alignment of raw material feeding, with manual operation support for easy adjustments.
- Cooling System: Prevents overheating of rollers and materials during forming, protecting machine components.
- Roll Forming System: The heart of the machine, shaping flat metal sheets into oval profiles via precision rollers with an interlocked seam.
- Transmission System: Drives the roll forming and feeding units synchronously, maintaining uniform forming speed.
- Cutting System: Trims finished oval pipes to your desired length, ensuring consistent dimensions.
- Control System: Centralizes operation of all components, simplifying parameter adjustments.
- Run-Out Supporting Rack: Supports finished pipes as they exit the machine, preventing bending or damage.
