Automatic steel pipe making machine

A Steel Pipe Making Machine is an industrial equipment used for producing welded steel pipes. It processes steel strips (coil) through a series of forming, welding, and shaping procedures to manufacture pipes of different specifications. These pipes are widely used in construction, machinery manufacturing, petrochemical, automotive, and furniture industries.

Main Components of a Steel Pipe Making Machine

1. Un-coiler: Holds and unwinds the steel coil, providing continuous raw material.
2. Forming Section:
   • A series of rollers gradually bend the steel strip into a tube shape.
   • The main forming methods include roller forming and mold forming.
3. Welding Section:
   • High-Frequency Welding (HF Welding): Uses high-frequency current to heat and weld the edges of the steel strip.
   • Other welding methods such as laser welding, submerged arc welding (SAW), and TIG welding are used for special-purpose pipes.
4. Sizing & Shaping Section:
   • Further adjusts the pipe size and shape to improve precision and appearance.
   • Can produce round pipes, square pipes, and rectangular pipes.
5. Cutting Section:
   • Uses flying saws or cold saws for inline pipe cutting.
6. Run-out Table & Stacking System:
   • Transports, cools, and collects finished pipes for further processing.

Main Types of Steel Pipe Making Machines

1. ERW Pipe Mill (Electric Resistance Welding): Uses high-frequency resistance welding (ERW) and is mainly used for producing thin- to medium-wall steel pipes.
2. SSAW Pipe Mill (Spiral Submerged Arc Welding): Forms the pipe in a spiral shape and welds it, suitable for manufacturing large-diameter pipes.
3. Precision Pipe Mill: Used for producing high-precision, small-diameter, or special-purpose pipes, such as automobile exhaust pipes and stainless steel pipes.

Applications of Steel Pipe Making Machines

• Construction Industry: Steel structures, scaffolding, pipe supports, etc.
• Oil & Gas Industry: Transmission pipelines, drilling equipment.
• Automotive Industry: Exhaust systems, vehicle frame pipes.
• Home Appliances & Furniture: Metal tables, chairs, railings, fences, etc.
