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

. Integrated with complementary products like SA210C Alloy Seamless Steel Pipe, I-beams, and Channel Steel, Baogang delivers comprehensive solutions for engineers prioritizing reliability and modular construction.

Key Specifications

Material:
- Carbon-manganese steel (SA210C / 25MnG equivalent) with optimized composition:
  - C: 0.22–0.30%, Mn: 0.70–1.00%, Si: 0.17–0.37%, P/S: ≤0.030%
Mechanical Properties:
- Tensile Strength: ≥485 MPa
- Yield Strength: ≥275 MPa
- 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

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
Seamless Construction: Eliminates weld seams, ensuring uniform strength and reducing failure risks under cyclic thermal and mechanical stresses .
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
Lightweight & Cost-Efficient: Reduces wall thickness by 10–20% compared to traditional materials (e.g., 20G), lowering material costs and improving heat transfer efficiency .
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
