Chinese Galvanized Pipe Making Machines Exporters

The best galvanized pipe rolling machine supplierin China will tell you that the process flow of the galvanized Pipe Rolling Machine mainly consists of the following key stages, which may be adjusted according to different production requirements:
1. Raw material preparation
Loading of galvanized steel strip: Fix the galvanized steel strip on the rack and supply it to the machine for continuous operation through the storage box.
Quality inspection: Check the uniformity of the zinc layer on the strip surface (≥275g/m²) and thickness, ensuring there are no scratches or rust.
2. Forming and welding
Forming processing: The strip is gradually bent into a tubular shape through the forming rollers, and high-frequency welding (ERW process) is used to achieve rapid welding by taking advantage of the skin effect.
Weld seam zinc plating: Use zinc wire with a zinc content of 99.99% to zinc plate the weld seam to ensure the same anti-corrosion performance as the pipe body.
3. Diameter control and straightening
Diameter control treatment: Adjust the outer diameter accuracy of the steel pipe through the shaping rollers, or change it to a square or rectangular pipe.
Straightening: The straightening rollers ensure the straightness of the steel pipe, with the error meeting industry standards.
4. Cutting and inspection
Flying saw cutting: Cut the pipe end at high speed (150-180 meters/minute) using a flying saw to ensure a smooth interface.
Weld seam inspection: Inspect the weld seam quality manually or using automated equipment, and downgrade the non-conforming products.
5. Surface treatment and packaging
Passivation treatment: Use an automatic spraying system to passivate the surface of the steel pipe, and the salt spray test should last for ≥18 hours without corrosion.
Labeling and packaging: Label the product information and automatically stack and pack, weigh and label.
Supporting equipment
Pre-treatment equipment: Acid washing tank, water washing tank, drying rack, etc.
Galvanizing equipment: Hot-dip galvanizing machine, external blowing/internal blowing device.
Auxiliary systems: Acid mist spraying, dust collector, intelligent monitoring system.
