Product Description

ASTM A249 TP316L Stainless Steel Welded Tube Bright Annealed Tube Heat Exchanger Tube

ASTM A249 TP316L is a welded stainless steel tube specification for superheater and heat exchanger service—made from low‑carbon, molybdenum‑bearing 316L steel, fully solution annealed after welding to restore corrosion resistance, and rigorously tested to ensure reliable performance under elevated temperatures and pressures. The surface condition of Bright Annealed is used where a smooth, decorative or ultra‑clean surface is required (e.g., pharmaceutical, food, or high‑purity heat exchangers).

ASTM A249/ASME SA249 welded tube
– More economical, often with tighter dimensional tolerances.
– Modern mills produce weld seams with properties matching the base metal when properly heat treated.
– Widely accepted for shell‑and‑tube heat exchangers and many superheater services.

Other Material Options for Superheater / Heat Exchanger

Beyond austenitic stainless steels, “others” may include:

Ferritic / Martensitic Alloys (e.g., T11, T22, T91) – Used in high‑pressure superheaters where corrosion is less of a concern but creep strength is critical. These are usually seamless under ASTM A213.
Nickel‑based Alloys (e.g., Alloy 600, 625, 800H) – For severe corrosion + high temperature, often in chemical plant heat exchangers or advanced power cycles.
Duplex Stainless Steels (e.g., S32205, S31803) – Occasionally used in heat exchangers for superior chloride stress corrosion cracking resistance, but generally not for superheater (high‑temperature) service due to embrittlement.

Application

Superheaters: Located in the convection section of boilers; these tubes raise the temperature of saturated steam above the saturation point.
Feedwater Heaters: Used to pre-heat boiler feedwater using extracted steam from the turbine.
Shell and Tube Heat Exchangers: Specifically for corrosive fluids (chemical processing, petrochemical, pharmaceutical).
Condensers: In power plants where cooling water (especially seawater or brackish water) is corrosive.

Very professional team, easy to talk to. We had some specific size requirements and they nailed it. The TP304 stainless tube with aluminum fins works like a charm for heat dissipation. Thumbs up!

Cost and reliability are key for Indian refineries. We installed these fin tubes in Mumbai’s cooling towers, achieving 16% energy savings versus local suppliers. ASTM A213 T11 compliance ensured no failures during monsoon humidity (90%+ RH), and the low price saved $8K upfront.
