Cold rolling technology enables the production of tubes with extremely precise control over outer diameter and wall thickness.
Outer Diameter Range: Typically Φ6mm ~ Φ273mm (small and medium diameters are its strength). Smaller capillary tubes (<Φ1mm) and larger sizes can be produced, but this range remains the mainstream.
Wall Thickness Range: 0.5mm ~ 20mm and above. Cold rolling is particularly adept at producing thin-walled to medium-thick-walled precision tubes.
Typical Specifications:
Precision Instrument Tubes: Φ10mm x 1.0mm
Heat Exchanger Tubes: Φ19mm x 2.0mm
Hydraulic Cylinder Barrels: Φ50mm x 5.0mm
Food Industry Tubes: Φ33.7mm x 1.5mm
Key Precision Indicators (Core Difference from Hot-Rolled Tubes)
This is the core value of cold-rolled tubes.
Dimensional Tolerances:
Outer Diameter Tolerance: Very stringent, typically controlled within ±0.10mm to ±0.30mm (depending on specifications).
Wall Thickness Tolerance: Equally stringent, typically around ±10% of the wall thickness, with higher requirements reaching ±5%. Excellent wall thickness uniformity.
Ovality: Excellently controlled, ensuring a near-perfect circular cross-section.
Length: Available in standard or multiple lengths to meet equipment manufacturing needs and reduce waste.
Surface Treatment and Condition: Depends on subsequent processing and usage requirements.
Industrial Pipe Surfaces:
Acid Pickling (AP): Silver-white or light gray matte surface with a uniform passivation film; a common delivery condition with good corrosion resistance.
Bright Finish (BA): After heat treatment under a protective atmosphere, the surface is mirror-like, with high internal cleanliness; suitable for demanding applications (e.g., food, electronics).
Cold-rolled (cold-drawn) state: The surface has a metallic cold-worked luster, high hardness, and requires further processing or can be used directly.
Decorative tube surface: Based on the above, further processing such as polishing (to mirror finish), wire drawing, sandblasting, and electroplating (titanium plating) can be performed.
