Steel pipe making machines (Tube Mills) are continuous, high-load industrial equipment. Proper operation and regular maintenance have a direct impact on equipment lifespan, production stability, and finished steel pipe quality. Standardized operation combined with systematic maintenance is essential to ensure long-term, stable performance of the tube mill.

Before each startup, basic inspections should be carried out to ensure the machine is in a safe and operable condition:
Check transmission components, couplings, and gearboxes for looseness or abnormalities
Ensure sufficient lubrication oil levels and smooth oil circulation
Inspect the electrical system, control cabinet, and emergency stop devices
Confirm that rollers are correctly installed with no obvious wear or cracks
Check that the welding, cooling, and cutting systems are ready for operation
Standard pre-startup inspections can effectively reduce the risk of unexpected failures.
The width, thickness, and material grade of the steel strip must match the design range of the tube mill. During operation, attention should be paid to:
Setting forming, welding, and sizing parameters according to process requirements
Preventing strip deviation or misalignment when entering the forming section
Adjusting welding power and squeezing force gradually to avoid sudden overload
Improper parameter settings may lead to poor weld quality, abnormal roller wear, or even equipment damage.
During operation, the tube mill should maintain continuous and stable production:
Avoid frequent starts and stops
Monitor weld seam formation, pipe diameter consistency, and surface quality in real time
In case of abnormal vibration, unusual noise, or unstable welding, immediately reduce speed or stop the machine for inspection
Unauthorized adjustments or forced troubleshooting during operation are strictly prohibited.
Lubrication is one of the core aspects of tube mill maintenance:
Regularly lubricate bearings, gears, and sliding parts according to the equipment manual
Keep lubricating oil clean and replace it periodically to prevent contamination
Clean steel scraps and oil residue from the machine surface and forming area after each shift
Proper lubrication and cleaning can significantly extend the service life of critical components.
Forming rollers and sizing rollers play a crucial role in pipe quality:
Regularly inspect roller wear and repair or replace damaged rollers in time
Re-align the center line after roller replacement or adjustment
Use dedicated roller sets for different pipe specifications and avoid mixing
Scientific roller management helps maintain stable pipe dimensions and consistent weld quality.
For ERW tube mills, special attention should be given to the welding and cooling systems:
Periodically inspect the high-frequency welding unit, cables, and grounding system
Ensure stable cooling water flow and clean water quality
Prevent scale or impurities from affecting weld quality and equipment heat dissipation
Stable welding performance is essential for ensuring weld seam strength.
Regularly inspect sensors, encoders, and control wiring
Keep the electrical control cabinet dry and clean
Analyze alarm signals promptly to avoid operating with faults
Proper electrical system maintenance helps reduce unplanned downtime and production interruptions.
Steel pipe manufacturers are advised to establish a systematic equipment maintenance plan:
Daily inspection: performed by operators every shift
Periodic maintenance: conducted weekly or monthly
Annual overhaul: comprehensive inspection of critical components
Standardized maintenance management effectively reduces failure rates and improves overall equipment efficiency.
