Tube Mill Machine – Operating Parameters and Customization

Successful tube mill operation depends on optimized process parameters that match material properties and desired tube specifications. At Shijiazhuang Faith Machinery Co., Ltd., engineers collaborate with clients to define critical parameters such as strip entry speed, forming roll set sequence, welding head power profile, and pulling tension. 

Strip speeds typically range from 20 to 120 meters per minute, with slower speeds preferred for thicker or high-strength materials to ensure complete weld penetration. Conversely, thinner low-carbon steels can be processed at higher speeds to maximize throughput.

Forming roll pressure is another key variable. Hydraulic or pneumatic systems apply controlled force to each roll, ensuring the strip edges meet with consistent contact. Overly high pressure can cause material thinning, while insufficient pressure leads to weld misalignment. Online force sensors measure roll load, feeding data back to the PLC for closed-loop control. 

Similarly, welding current and voltage profiles are programmed to match material thickness and grade: two-wire SAW configurations use separate amperage settings for root and cap wires, whereas induction welding adapts frequency based on strip width to optimize heating zones.

Customization options abound at Shijiazhuang Faith. Clients may choose single-stand or multi-stand forming sections; dual-welding heads for tandem operation; or specialized cooling and scarfing units to remove excess weld bead material. For industries requiring coating—such as galvanizing or polymer linings—the machine line can be extended with inline pickling, coating, and curing stations. Data acquisition modules capture every parameter throughout the run, storing it in SQL-based databases that integrate with client enterprise resource planning (ERP) systems for full production transparency.

Machine layouts are tailored to factory floor constraints, with options for straight-line, L-type, or U-type configurations. Utilities such as power supply, gas lines, and cooling water are consolidated within modular skid units to simplify installation and reduce utility plumbing. Comprehensive commissioning protocols include trial runs, dimensional validations, and weld testing according to customer-specified standards (e.g., ASTM, EN, JIS). 

By offering parameter flexibility, auxiliary equipment integration, and customizable layouts, Shijiazhuang Faith’s tube mill machines help manufacturers optimize production costs and adapt to evolving market demands.
