Precision Bright Steel Pipe

Precision Bright Steel Pipe is precision cold-drawn and bright annealed for tight tolerances and a smooth surface, helping reduce machining, improve assembly accuracy, and ensure reliable performance in precision industrial applications.

Advanced cold-drawing processes achieve an outer diameter tolerance of up to ±0.02 mm, directly reducing your secondary machining and production costs.

Controlled atmosphere heat treatment delivers a tensile strength of 400–900 MPa alongside an elongation of ≥10%, ensuring structural integrity during severe bending and flaring.

Surface roughness ranging from 0.1 to 0.8 um to meet standard smoothness requirements for fluid and mechanical applications.

Controlled straightness and internal stress relief improve stability during CNC machining, tube bending, welding, and automated assembly.

Precision Cutting: Exact length cutting with tight tolerances and strict burr-free removal.

End-Finishing: Professional both-end chamfering or facing to match automated welding or assembly setups.

Special Treatment: Tailored anti-rust oil application and customized length sorting for direct line-side delivery.

Automotive Industry: Transmission shafts, shock absorber cylinders, and steering columns.

Fluid & Hydraulics: High-pressure hydraulic systems, pneumatic cylinders, and precision fluid lines.

Industrial Automation: Robotic arms, linear motion guides, and heavy-duty mechanical components.

Other Sectors: Textile machinery, medical equipment, and fitness apparatus.

Raw Material Inspection: Spectrometer testing for chemical composition verification before production starts.

Dimensional Monitoring: Laser outer diameter controllers and digital wall thickness gauges operating in real-time during cold-drawing.

Non-Destructive Testing (NDT): 100% online eddy current testing (ET) to detect inner and outer surface flaws or micro-cracks.

Final Physical Testing: Tensile strength testing, flattening/flaring tests, and surface roughness measurement per batch.

EN 10204 3.1 Mill Test Certificates: Complete metallurgical traceability including heat number, chemical composition, and mechanical test results.

Independent Inspection: SGS, TUV, or BV pre-shipment inspection reports available upon request to verify physical dimensions and surface quality.
