Bright Welded Steel Tube

Bright Welded Steel Tubes are manufactured using high-quality carbon steel, alloy steel, or stainless steel strips through precision cold forming, high-frequency ERW welding, sizing, and protective atmosphere bright annealing processes.

Bright Surface Finish: Utilizing a protective atmosphere bright annealing process, effectively reducing oxide layers and surface defects, resulting in a smooth and uniform inner and outer surface of the steel pipe.

Precision Dimensional Control: Outer diameter, wall thickness, and roundness tolerances are controlled through precision forming, ERW welding, and sizing processes.

Reliable Weld Quality: Employing high-frequency ERW welding technology, combined with eddy current testing and performance evaluation, weld quality is controlled to ensure stable strength and reliable performance in the welded area.

Excellent Machining Performance: Through appropriate material selection and annealing treatment, the steel pipe possesses good toughness and ductility, making it suitable for cutting, bending, flaring, flattening, and welding.

Raw Material Inspection: High-quality steel strip is used. Before entering the factory, its chemical composition, mechanical properties, and surface quality are tested to ensure stable and reliable raw materials.

Precision Forming & ERW Welding: The steel strip undergoes continuous precision forming and high-frequency ERW welding to form stable welds, ensuring tube consistency.

Bright Annealing: Annealing in a protective atmosphere improves material microstructure, reduces welding stress, and maintains good surface quality.

Sizing & Straightening: Precision sizing and straightening control dimensions, tolerances, and straightness to meet precision application requirements.

Final Inspection: Before leaving the factory, dimensions, surface, welds, and mechanical properties are inspected to ensure products meet customer standards.

Size Customization: Customization of outer diameter, wall thickness, length, and tolerances is supported to meet the needs of different equipment and components.

Material Customization: Offers various material options including carbon steel, alloy steel, and stainless steel to meet different strength and environmental requirements.

Surface Customization: Supports surface treatments such as glossy finishes, polishing, and rust-preventive oiling to improve product appearance and storage performance.

Packaging Customization: Provides moisture-proof packaging, steel strapping, iron frame packaging, and customer labeling services to meet export shipping needs.

Export Packaging: Employs rust-proof treatment, moisture-proof packaging, end protection, and steel strapping to reduce the risk of damage during transportation.

Shipping Support: Supports FCL (Full Container Load) and LCL (Less than Container Load) shipping and provides optimized container loading solutions.
