Small diameter seamless steel pipe

Product Name: SA210C Steel Pipes for Power Station Boilers

Product Description

China Baogang Steel Union (Baogang Group), a globally recognized leader in advanced steel manufacturing, offers SA210C Steel Pipes engineered for high-performance power station boilers. Compliant with ASME SA210, GB/T 5310, and EN 10216 standards, these seamless carbon-manganese steel pipes combine exceptional high-temperature strength, corrosion resistance, and weldability, making them ideal for critical components like water-cooled walls, economizers, and low-temperature superheaters in large-capacity power plants

Key Specifications

  • Elongation: ≥20%
  • Hardness: ≤179 HB 
     
• Dimensions:
  • Outer Diameter (OD): 26–65 mm (standard) or custom up to 508 mm
  • Wall Thickness: 2.4–7 mm (HRSG applications) or up to 50 mm for heavy-duty boilers
  • Length: 6–12 meters (custom-cut available) .
• Surface Treatment: Hot-dip galvanized, varnished anti-rust coating, or 3LPE coating for enhanced durability in harsh environments .

Core Features

1. High-Temperature Performance: Designed for long-term operation at temperatures up to 500°C, ideal for water-cooled walls, economizers, and superheaters in 300MW–600MW power stations 
    
2. Seamless Construction: Eliminates weld seams, ensuring uniform strength and reducing failure risks under cyclic thermal and mechanical stresses .
3. Corrosion & Oxidation Resistance: Optimized Mn and Si content enhances resistance to hydrogen-rich and acidic environments, while coatings extend service life in marine and industrial settings 
    
4. Lightweight & Cost-Efficient: Reduces wall thickness by 10–20% compared to traditional materials (e.g., 20G), lowering material costs and improving heat transfer efficiency .
5. Integrated Structural Solutions: Compatible with I-beams (ASTM A992) for boiler frameworks, Angle Steel (Q345B) for bracing, and Channel Steel (UPN/UPE) for modular assembly
6.
