Overview of the Oval Pipe Roll Forming Machine
The oval pipe roll forming machine is specifically engineered to continuously produce oval-shaped steel pipes with precise cutting lengths. Pipes made from galvanized steel using this machine are widely used as electric conduits.
Electric wiring ducts or conduits are available in various materials, including metal, plastic, fiber, or fired clay, and are typically manufactured in round or oval shapes. Among the available production methods, roll forming stands out as the most efficient and reliable solution for creating oval pipes or conduits.
This machine, designed for manufacturing oval-shaped electric conduits or wiring ducts, is composed of several key components:
a 3-ton manual decoiler,
a feeding system,
a cooling unit,
a roll forming mechanism,
a transmission setup,
a cutting system,
a control system,
a run-out support rack.
1)Use Servo motor shearing:
Flying and tracking cutting saw,the cutting saw will adjust
the cutting speed and location according to the main machine speed.By this method,the machine working speed will be same as the main machine accordingly.The cutting plate we take the best material for cutting it in high speed and beautiful cutting scare.
2)The material of blade:Cr12Mov,Hardening HRC 58-62C
3)Length Tolerance:3m+1.5mm
4)Flying cutting saw,can make sure the perfect shape after shearing.
5)Note:this type shearing syste could support three sizes of pipes.
The machine features an independent forming stand structure, with each stand coated in electro-chrome for durability. A tracking fly-saw cutter is integrated to ensure continuous production without stopping during the cutting process. The PLC control system facilitates fully automated and uninterrupted operation; users simply input the required cutting lengths and quantities, and the machine handles the rest.
This machine processes raw materials such as galvanized steel or pre-painted steel with a thickness of 0.3 to 0.6 mm. For added flexibility, manual operation options are included, allowing operators to adjust settings easily when processing materials of varying thicknesses.
What is oval pipe used for?
An oval duct is an oval-shaped tube used as a passageway for air conditioning, heat, and other HVAC services.
What is difference between tube and pipe?
Tubes are used in applications such as medical devices that require a precise outside diameter. The outside diameter is important since it will indicate how much it can hold as a stability factor. Pipes are used for transporting gasses or liquids making it important to know the capacity.

How to test the quality of oval tube size?
RFQ About the interlock oval tube rolling forming machine:
Question: Can one machine produce multiple sizes of oval tubes?
Answer: Using a single set of molds, it is not feasible to produce multiple sizes. However, we offer a fast-change design that reduces costs by utilizing shared components like the decoiler, PLC shearing system, motor, and others. This fast-change system allows all rollers and shafts to be mounted on a base frame, making it easy to swap the frame for a different size. Depending on customer needs, the fast-change design can be an economical option or a high-quality solution. We can customize the machine entirely according to specific requirements.
Question: What is interlock, and how does it differ from welding?
Answer: Interlocking is a method of closing seams by bending and folding, suitable for thin sheets with a thickness of up to 1.2 mm. For sheets thicker than 1.2 mm, welding becomes the only viable option for seam closure. Welding methods include TIG welding, laser welding, and HF welding.
Question: How are tubes connected to each other?
Answer: Our machine includes a necking feature that reduces one tube’s size and adds ribs, allowing it to fit tightly into another tube. This design ensures a secure connection between tubes.
