A213/SA213 TP304L Bright Annealed U-Bend Tube Overview

 

A213/SA213 TP304L Bright Annealed U-bend tubes are high-performance stainless steel tubes manufactured to ASTM A213/ASME SA213 standards using TP304L material—an austenitic stainless steel with low carbon content. These tubes undergo a bright annealing process in a controlled atmosphere to achieve a smooth, reflective surface finish and enhanced corrosion resistance.

 

The U-bend shape is specifically designed for use in heat exchangers, condensers, and boilers, where fluid direction changes within a compact footprint. The combination of TP304L's excellent weldability and corrosion resistance makes these tubes ideal for high-temperature and corrosive environments in industries such as petrochemical, power generation, and marine engineering.

Mechanical Properties of SS304L (UNS S30403)

 

Property Value
Tensile Strength (min) 485 MPa (70 ksi)
Yield Strength (min) 170 MPa (25 ksi)
Elongation (min) 35%
Hardness (max) 90 HRB (Rockwell B)

Melting Point ~1400–1450 °C (2550–2640 °F)

 

 

 

1. Key Features

  • Material: TP304L (UNS S30403) – low carbon version of 304 stainless steel

  • Process: Seamless, cold-worked, and bright annealed

  • Finish: Bright, smooth, oxide-free internal and external surface

  • Bend Radius: Customizable (typically 1.5×OD, 2×OD, etc.)

  • Standards: ASTM A213 / ASME SA213

  • Size Range: OD 6–38 mm; WT 0.5–3.0 mm; Lengths up to 30 meters (straight) before bending

 

 

2. Why Choose Bright Annealed (BA) tubes instead of Pickled Annealed (PA) tubes?

 

Choose Bright Annealed tubes when:

  • You need high surface quality and cleanliness

  • Corrosion resistance is a priority in critical environments

  • Applications demand tight tolerances and aesthetics

Pickled annealed tubes are fine for more general-purpose industrial applications where surface finish isn't as critical.

 

 

3. Advantages

  • Superior corrosion resistance, especially in chloride and acidic environments

  • Smooth internal surface enhances fluid flow and reduces scaling

  • High dimensional accuracy and mechanical strength

  • Suitable for high-purity and high-temperature applications

 

 

4. Applications

  • Heat exchangers

  • Condensers

  • Boilers and superheaters

  • Power generation and petrochemical plants

  • Pharmaceutical and food processing equipment
