Detailed Product Description

Precision forged stainless steel seamless tubes - anodizing treatment of mechanical components

 

Description :
Our precision-forged stainless steel seamless tubes are engineered for high-performance mechanical components requiring exceptional strength, corrosion resistance, and dimensional accuracy. Through advanced hot-forging and CNC machining processes, we deliver seamless tubular parts with superior structural integrity compared to conventional welded or cast alternatives. The optional anodizing treatment further enhances surface hardness and wear resistance for demanding industrial applications.

 

Key Features & Benefits :
✔ Premium Material: Forged from 304/316L or 17-4PH stainless steel for optimal strength-to-weight ratio and chemical resistance
✔ Seamless Construction: Eliminates weld weak points, ideal for high-pressure fluid/gas systems
✔ Precision Machining: CNC-turned to ±0.05mm tolerances for critical bearing/sleeve applications
✔ Anodized Finish:

  • Type II (Sulfuric acid) anodizing for corrosion protection
  • Type III (Hardcoat) anodizing up to 70+ Rockwell C hardness
  • Custom color options (black, gold, etc.) available
    ✔ Thermal Stability: Withstands continuous service temperatures from -200°C to +400°C

  • Certifications: ISO 9001, ASME B36.19M, PED 2014/68/EU

FAQ:

1. What are the advantages of forged seamless tubes vs. welded tubes?

  • Superior Strength: No weld seams eliminate weak points (30% higher fatigue life)

  • Better Integrity: Homogeneous grain structure from hot forging

  • Higher Pressure Rating: Withstand 2-3x more internal pressure than welded equivalents

  • Precision: Tighter OD/ID tolerances (±0.05mm achievable)

2. Which stainless steel grades do you recommend for specific environments?

  • 304: General corrosion resistance (food, chemical)

  • 316L: Marine/offshore (chloride resistance)

  • 17-4PH: High-strength applications (aerospace)

  • 2205 Duplex: Extreme corrosion + stress corrosion cracking resistance

3. Can you achieve mirror finishes on internal surfaces?

Yes, we provide:

  • Mechanical polishing: Ra ≤0.2μm (ID ≥15mm)

  • Electropolishing: For micro-smooth surfaces (FDA-compliant)

4. What certifications do your tubes comply with?

  • Quality: ISO 9001, AS9100

  • Material: ASTM A312/A790, EN 10216-5

  • Pressure: PED 2014/68/EU (Category IV)

  • Special: NACE MR0175 for sour service

5. How do you test tube quality?

  • 100% Dimensional: Laser gauging + CMM

  • Material: Eddy current + ultrasonic testing

  • Pressure: Hydrostatic testing to 1.5x rated pressure

  • Surface: Salt spray (ASTM B117) + hardness testing
