What is a pipe forming machine?

The Pipe Manufacturing Machine is a specialized equipment used for continuous production of metal or plastic pipes. Through processes such as roll forming, welding, and sizing, the coil material is processed into pipes of different specifications.
I. Core Working Principle
Unrolling and straightening: After the metal coil is unwound, it passes through the straightening machine to eliminate stress.
Forming and welding: Multiple sets of rollers gradually roll the sheet material into a tubular shape, and high-frequency current melts the edges to achieve welding (welding machine).
Sizing and cooling: The outer diameter of the pipe is adjusted by a precise mold, and the weld seam is solidified by the water cooling system.
Cutting and collection: The flying saw cuts according to the set length, and the automated stacking device completes the collection.
II. Technical Development Highlights
Digital control: PLC and touch screen are used to realize real-time parameter adjustment, with an error control of ±0.1mm
Energy optimization: The new medium-frequency power supply is 15%-20% more energy-efficient than traditional equipment
Multifunctional integration: Some models can be compatible with various cross-sectional shapes such as round pipes, square pipes, and elliptical pipes for production
III. Typical Application Scenarios
Construction engineering: Scaffolding pipes, fire protection pipes (Φ20mm - Φ200mm)
Automotive manufacturing: Exhaust pipes, precision pipes for transmission shafts (wall thickness 0.5 - 3mm)
Appliance industry: Air conditioning condensation pipes, washing machine drainage pipes, etc. (anti-corrosion galvanized pipes) The current mainstream equipment has achieved a production speed of 30 meters per minute. In the future, it will develop towards intelligent detection (such as online eddy current testing) and flexible production.
