ASME SA249 TP304 Bright Annealed Stainless Steel Welded Tube For Refrigeration System

 

ASME SA249 TP304 stainless steel welded Tube is a high-precision, longitudinally welded stainless steel tube specifically designed and manufactured for use in critical heat exchange and fluid conveyance applications, most notably in refrigeration and air-conditioning systems. It conforms to the ASME SA249/ASTM A249 specification, which is the standard for welded austenitic steel boiler, superheater, heat-exchanger, and condenser tubes. ASTM A249 TP304 Stainless steel bright annealed tubes have different polished grades, such as 180#, 320#, 400#, 600#, 800# grit. In refrigeration systems (including chillers, condensers, evaporators, and direct expansion coils), these tubes serve as the essential conduit for refrigerants or water/brine. The combination of TP304 stainless steel (offering excellent corrosion resistance, toughness, and weldability) with the bright annealed finish creates a tube that is inherently clean, resistant to oxidation, and has a low surface roughness that minimizes pressure drop and inhibits scale/bacterial adhesion. This makes it superior to plain carbon steel or non-annealed welded tubes in terms of longevity, efficiency, and system purity.

Key Features Of A249 TP304 SS Tubes:

  • Excellent Corrosion Resistance: TP304 offers strong resistance to refrigerants, water, brine, and atmospheric corrosion.
  • High Purity & Cleanliness: The BA process ensures a scale-free, ready-to-use surface, preventing system contamination.
  • Superior Hydraulic Performance: Smooth interior surface reduces friction and pressure drop.
  • High Strength & Ductility: Good mechanical properties for bending, expanding, and flaring.
  • Excellent Weldability & Formability: Easy to fabricate into coils, bends, and assemblies.
  • Hygienic & Sanitary: Non-porous, easy to clean, compliant with food-grade standards.
  • Aesthetic Appeal: The bright, shiny finish is desirable for visible components.

 

Benefits Of Bright Annealed (BA) finish:

  • No scale, no pickling required: The surface is clean and passive.
  • Superior corrosion resistance: The undisturbed, chromium-rich oxide layer is fully intact.
  • Hygienic & cleanable: Ideal for food, beverage, and pharmaceutical cooling.

 

Different Applications Of ASME SA249 TP304 SS Welded Tubes:

1. Primary Application: Refrigeration & Air-Conditioning Systems:

  • Shell & Tube Heat Exchangers: As the tube bundle for condensers and evaporators.
  • Direct Expansion Coils / Finned Tube Heat Exchangers: For air-cooling units.
  • Receiver Tanks, Intercoolers, Oil Coolers.
  • Ammonia Refrigeration Systems: Where copper is incompatible.

 

2. Other Critical Applications:

  • Food, Beverage & Pharmaceutical Processing: Sanitary process lines, pasteurizers.
  • Chemical & Petrochemical: Instrumentation lines, sample lines, heat exchangers for non-severe corrosives.
  • Power Generation: Low-pressure boiler tubes, instrumentation lines
  • Automotive: Exhaust system components, fuel lines.
  • Architectural: Handrails, decorative structures where a BA finish is required.
