ASME SA213 TP444 Stainless Steel U Bend Heat Exchanger Tube




Introduction


The ASME SA213 TP444 is a ferritic stainless steel tube designed for high-temperature and corrosive environments, commonly used in heat exchangers, boilers, and superheaters. The U-bend design allows for thermal expansion and efficient heat transfer in shell-and-tube heat exchangers.


Material Specifications


Standard: ASME SA213 (Seamless Ferritic and Austenitic Alloy-Steel Boiler, Superheater, and Heat-Exchanger Tubes)

Grade: TP444 (A ferritic stainless steel with improved corrosion resistance)

UNS Designation: S44400

Hardness (Rockwell B)

≤ 90 HRB


Key Features & Advantages


Excellent Corrosion Resistance – Resists pitting, crevice corrosion, and stress corrosion cracking (SCC) in chloride environments.
High-Temperature Performance – Suitable for heat exchangers operating in elevated temperatures.
Ferritic Structure – Magnetic, with good resistance to oxidation and scaling.
Stabilized with Ti/Nb – Prevents sensitization and intergranular corrosion.
U-Bend Design – Allows thermal expansion, reduces stress, and improves heat transfer efficiency.


Applications


Shell-and-tube heat exchangers

Condensers & evaporators

Power plant boilers & superheaters

Chemical processing equipment

Oil & gas refineries


Manufacturing & Testing


Seamless construction (cold-drawn or hot-finished)

U-bend forming (cold bending with precise radius)

Non-destructive testing (NDT) (Eddy current, hydrostatic, ultrasonic)

Heat treatment (Annealed for optimal corrosion resistance)


Comparison with Other Grades


Grade

Type

Key Difference

TP304/TP316

Austenitic

Higher Ni content, better toughness

TP430

Ferritic

Lower Mo, less corrosion resistance

TP444

Ferritic

Higher Mo & stabilization, better chloride resistance


Conclusion


The ASME SA213 TP444 U-bend tube is ideal for corrosive and high-temperature heat exchanger applications, offering superior chloride resistance compared to standard ferritic grades. Its U-bend design enhances thermal performance while minimizing mechanical stress.
