1. ASTM A335 Grade P22 is a chromium-molybdenum alloy steel with the following specifications:

  • Chemical Composition
Grade UNS Designation C Mn P S Si Cr Mo Other
P22 K21590 0.05–0.15 0.30–0.60 0.025 0.025 0.50 max 1.90–2.60 0.87–1.13 . . .

 

  • Mechanical Properties:
  • Tensile Strength: ≥415 MPa (60,200 psi)

    Yield Strength: ≥205 MPa (29,700 psi)

    Hardness: ≤163 HBW (Brinell)

    Elongation: ≥30% (in 50mm)

  • Heat Treatment

Normalized at 900–975°C (1652–1787°F) and tempered at 675–760°C (1247–1400°F).

 

 

2. Manufacturing Standards & Testing

Compliance:

ASTM A335 (material)

ASME BPVC Section I & VIII (pressure design)

TEMA (Thermal Exchanger Manufacturers Association) for finned tube bundles.

 

Testing:

Hydrostatic Test: 1.5x design pressure for 10+ seconds.

NDT (Non-Destructive Testing):

Ultrasonic testing (UT) for base tube integrity.

Dye penetrant testing (PT) for weld joints.

 

 

3. Application-Specific Configurations

Power Plant Boilers:

Superheaters: Fins optimized for 400–600°C flue gas with ash erosion resistance.

Economizers: Low-fin-density designs (3–5 FPI) to minimize fouling.

 

Refinery Heaters:

Stainless steel fin tips for sulfidation resistance in H₂S-rich environments.

 

Waste Heat Recovery Units:

Custom fin spacing to handle particulate-laden exhaust (e.g., cement kilns).

 

 

4. Advantages Over Serrated/Embedded Fins

  • Durability: No risk of fin loosening or debris entrapment (critical in ash/slag environments).
  • Thermal Fatigue Resistance: Monolithic construction handles rapid temperature swings.
  • Ease of Cleaning: Smooth fin surfaces reduce fouling in dirty gas streams.
