hollow tube forming machine
hollow tube forming machine (also called a tubular roll forming machine or hollow section forming line) is an industrial equipment system used to produce seamless or welded metal tubes and hollow profiles from coiled or sheet metal.
Key Features & Functions
1. Working Principle
Material Feeding: Uncoils and flattens metal strips (steel, stainless steel, aluminum).
Pre-forming: Gradually bends the strip into a tubular shape through multiple roller stations.
Welding (if applicable): Uses high-frequency (HF) welding, TIG welding, or laser welding to seal the seam for closed tubes.
Sizing & Calibration: Precisely adjusts the tube diameter and wall thickness.
Cutting: Cuts tubes to specified lengths (flying saw, servo cutter, or hydraulic shear).
2. Types of Hollow Tube Forming Machines
Round Tube Forming Machine - Produces circular hollow sections (CHS).
Square/Rectangular Tube Forming Machine - Manufactures square hollow sections (SHS) and rectangular hollow sections (RHS).
Oval & Custom Profile Tube Machine - For specialized shapes (e.g., oval, D-shaped, or multi-sided tubes).
Spiral Tube Forming Line - Used for spiral-welded pipes (large-diameter applications).
3. Applications
Construction: Scaffolding, structural frameworks, fencing.
Automotive: Exhaust pipes, chassis components.
Furniture: Chair frames, table legs.
HVAC & Plumbing: Ducting, conduit pipes.
Industrial Machinery: Hydraulic cylinders, conveyor systems.
4. Advantages
High-speed production (10-60 m/min, depending on material). Precision forming (±0.1mm tolerance achievable). Flexible customization (adjustable rollers for different sizes). Material savings (minimal waste compared to extrusion).
