Deskripsi Produk

ASTM A269 TP316L Stainless Steel Welded Tube Bright Annealed Tube Heat Exchanger Tube

ASTM A269 TP316L bright-annealed welded tube is a high-performance solution for heat exchangers. This specification covers longitudinally welded austenitic tubes with low carbon (≤0.035%) to prevent intergranular corrosion—critical for thermal equipment. Bright annealing in a controlled atmosphere yields a clean, scale-free surface that minimizes fouling, enhances heat transfer, and ensures purity, making the tube ideal for chemical, pharmaceutical, food, and ultra-pure water systems. Although ASTM A269 is a general service standard, its tight tolerances, smooth weld seam, and corrosion resistance offer a cost-effective alternative to seamless tubing when ASME A249 compliance is not required.

Pressure / Mechanical Integrity

Seamless has no weld seam → inherently stronger for high pressure (e.g., > 3000 psi) and cyclic fatigue applications. Preferred for ASME Section VIII, high‑pressure steam, hydraulic lines.
Welded (with BA) – after bright annealing, the weld recrystallizes and has properties nearly equal to the base metal. Suitable for low to medium pressure (typically < 1500 psi) and non‑cyclic service.

Why Bright Annealed for Heat Exchangers?

For heat exchanger service, surface quality directly impacts performance. The BA finish offers distinct advantages:

No Scale or Oxide: Eliminates "chalking" or flaking that could contaminate process fluids or block small tubes.
Smoother Surface (Ra ≤ 20 µin typical): Reduces fouling (deposit buildup) and improves heat transfer efficiency compared to pickled or as-welded surfaces.
Cleanliness: Ready for high-purity applications (pharma, food, ultra-pure water) without chemical cleaning.
Uniform Corrosion Resistance: The weld is fully solution annealed, eliminating galvanic effects between weld and base metal.

Application

Shell & Tube Heat Exchangers (condensers, evaporators, chillers)
U-tube bundles (BA finish allows bending without cracking)
Hydraulic & Instrumentation lines in corrosive environments
Pharmaceutical / Biotech (clean steam, WFI systems)
Chemical processing (acetic acid, chlorides, sulfites)

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!
