Seamless High Precision Cold-Rolled Tube is a tubular product characterized by its near-perfect dimensional accuracy, superior surface finish, and enhanced mechanical properties. Unlike standard pipes, these are engineered for applications where precision, reliability, and performance are critical.
The cold-rolling process enhances surface hardness (up to 30% increase in yield strength) while maintaining excellent ductility, making it ideal for high-precision fluid systems.
Features
Extreme Dimensional Precision: Offers OD/ID concentricity ≤0.05 mm and straightness ≤0.1 mm/m, critical for applications like hydraulic actuators and precision instruments.
Superior Surface Finish: Internal/external surface roughness (Ra ≤0.4 μm) reduces fluid friction and prevents particle accumulation, essential for high-purity systems.
Enhanced Mechanical Properties: Cold work increases tensile strength (e.g., 316L cold rolled: 700 MPa vs. 500 MPa annealed) while maintaining elongation >30%.
Material Versatility: Available in carbon steel (for general structural use), stainless steel (corrosion resistance), and exotic alloys (Inconel 625 for extreme environments), with wall thicknesses ranging 0.5-10 mm.
Application
Aerospace Hydraulics: Used in aircraft flight control systems, landing gear tubing, and fuel lines requiring leak-free performance at 3000+ PSI.
Medical Equipment: Ideal for surgical instrument shafts, endoscope tubes, and dialysis machine lines, meeting ISO 13485 cleanliness standards.
Semiconductor Manufacturing: Employed in ultra-high-purity gas delivery systems (e.g., silicon wafer fabrication), resisting particle contamination and corrosive gases.
Industrial Automation: Used in robotic arm hydraulics, CNC machine tool pipelines, and precision lubrication systems requiring minimal pressure drop.
