Key Characteristics
- High dimensional accuracy: Cold drawing process yields tight tolerances on diameter, wall thickness, and bend radii.
- Excellent heat transfer performance: Low carbon content and smooth internal surface support efficient condenser service.
- Good formability & weldability: Suitable for U-bend forming and joint fabrication without compromising structural integrity.
Our Manufacturing Advantages
- Industry-Compliant Quality Assurance
We ensure all tubes meet the chemical and testing requirements of ASTM A179, including product analysis, flattening, flaring, hardness, and hydrostatic testing when applicable -- demonstrating conformity and reliable service life. - Precision U-Bend Fabrication
Custom U-bend forming is performed using controlled bend tooling with minimal deformation or compromise to wall thickness -- minimizing stress points and maintaining consistent heat exchanger performance. - Customizable & Flexible Supply
Wall thickness ranges (0.6 - 30 mm), lengths, and bend configurations are tailored to customer designs, with detailed mill test certifications per ASTM standards.
Execution Standards
- ASTM A179/A179M: Seamless cold-drawn low-carbon steel heat-exchanger and condenser tubes.
- Compatible with ASME SA-179 (identical mechanical and material specification).
Typical Applications
Condenser Tubes for Power Plants & Industrial Heat Exchangers
Used as precision U-bend tubes in shell-and-tube condensers and heat exchangers where efficient heat transfer and dimensional quality are critical.
