ASTM A312 TP316L Helical Spiral Serrated Finned Tube With SS316L Fins For Heat Exchanger

 

ASTM A312 TP316L Helical Spiral Serrated Finned Tube with SS316L Fins is a specialized type of heat exchanger tube designed for enhanced heat transfer efficiency in demanding environments.

 

Here's a detailed breakdown of its components and features:

1. Base Tube – ASTM A312 TP316L

(1). Chemical Composition of ASTM A312 TP316L (Weight %)

Element Minimum Maximum
Carbon (C) - 0.03%
Manganese (Mn) - 2.00%
Phosphorus (P) - 0.045%
Sulfur (S) - 0.030%
Silicon (Si) - 1.00%
Chromium (Cr) 16.0% 18.0%
Nickel (Ni) 10.0% 14.0%
Molybdenum (Mo) 2.0% 3.0%
Nitrogen (N) - 0.10%
Iron (Fe) Balance Balance

Notes:

Low carbon (≤0.03%) prevents carbide precipitation during welding (prevents sensitization).

Molybdenum (2-3%) enhances corrosion resistance, especially against chlorides and acids.

 

(2). Mechanical Properties of ASTM A312 TP316L

Property Value (Seamless & Welded)
Tensile Strength (MPa) ≥485 MPa (70 ksi)
Yield Strength (0.2% Offset, MPa) ≥170 MPa (25 ksi)
Elongation (% in 50 mm) ≥35% (for longitudinal)
Hardness (Rockwell B) ≤95 HRB (Annealed Condition)

Notes:

Good ductility (≥35% elongation) ensures formability and weldability.

Lower yield strength compared to carbon steel but excellent toughness.

Annealed condition provides optimal corrosion resistance.

 

(3). Key Takeaways

  • TP316L is ideal for corrosive & high-temperature applications (e.g., chemical processing, marine, heat exchangers).
  • Low carbon makes it suitable for welding without post-weld heat treatment.
  • Molybdenum boosts resistance to pitting/crevice corrosion.

2. Fins – SS316L (Stainless Steel 316L)

The fins are made of the same material as the base tube (SS316L) for compatibility and corrosion resistance.

 

Helical Spiral Serrated Design:

Helical Spiral: Fins are wound in a continuous spiral around the tube, increasing surface area for better heat transfer.

Serrated: Fins have notched (serrated) edges, further enhancing turbulence and heat exchange efficiency.

 

3. Key Features

  • Enhanced Heat Transfer: The serrated spiral fins disrupt laminar flow, improving thermal performance.
  • Corrosion Resistance: Ideal for aggressive environments (chemical processing, marine, oil & gas).
  • High-Temperature Suitability: Maintains strength and oxidation resistance at elevated temperatures.

4. Advantages Over Plain Tubes

  • Higher heat transfer efficiency in compact spaces.
  • Reduced fouling due to turbulent flow induced by serrations.
  • Long service life due to SS316L’s corrosion resistance.

 

Applications of ASTM A312 TP316L Helical Spiral Serrated Finned Tube with SS316L Fins

This specialized finned tube is designed for high-efficiency heat transfer in corrosive and high-temperature environments. Its SS316L material (both tube and fins) ensures excellent resistance to oxidation, chlorides, acids, and thermal stress, making it suitable for demanding industrial applications.

 

1. Petrochemical & Oil & Gas Industry

  • Heat exchangers & condensers in refineries.
  • Gas cooling systems (e.g., natural gas processing).
  • Waste heat recovery units (e.g., flue gas heat exchangers).
  • Offshore platforms (seawater-resistant cooling systems).

Why?

Resists sulfuric acid, chlorides, and sour gas (H₂S) corrosion.

Handles high-pressure steam and hydrocarbons.

 

2. Power Generation (Thermal & Nuclear Plants)

  • Boiler tubes & economizers (heat recovery from exhaust gases).
  • Condensers & feedwater heaters.
  • Nuclear reactor cooling systems (secondary loops).

Why?

High thermal conductivity with serrated fins improves efficiency.

Resists scaling and oxidation at high temperatures.

 

3. Chemical & Pharmaceutical Processing

  • Acid cooling systems (e.g., sulfuric, hydrochloric acid).
  • Solvent condensers & evaporators.
  • Reactor cooling jackets.

Why?

SS316L’s Mo content (2-3%) resists pitting from aggressive chemicals.

Low carbon prevents carbide precipitation during welding.

 

4. Marine & Desalination Systems

  • Seawater-cooled condensers.
  • Desalination plant heat exchangers.
  • Shipboard cooling systems.

Why?

Excellent chloride resistance (prevents pitting/crevice corrosion).

Helical spiral fins reduce fouling from salt deposits.

 

5. Food & Beverage Industry

  • Pasteurizers & sterilizers.
  • High-temperature processing heat exchangers.

Why?

Sanitary SS316L surface (easy to clean, non-reactive).

Corrosion-resistant against acidic/alkaline food products.

 

6. HVAC & Refrigeration

  • Industrial chillers & refrigerant condensers.
  • Waste heat utilization in district heating.

Why?

Serrated fins enhance turbulence, improving heat transfer.

Resists Freon, ammonia, and brine corrosion.

 

7. Waste Incineration & Exhaust Gas Treatment

  • Flue gas heat recovery systems.
  • Air preheaters & scrubber coolers.

Why?

Withstands acidic exhaust gases (SOx, NOx, HCl).

High-temperature durability (up to ~900°C with proper grade).
