Product Overview
The ASTM A335 P22 HFW Solid Finned Tube with 11-13 Cr Fins is engineered for high-temperature and high-pressure applications in power generation, petrochemical, and oil and gas industries.
Key Features
- High-Frequency Welded (HFW) base tube for strong, seamless-like performance
- Solid fins integrally bonded for maximum durability and heat transfer
- 11-13% Chromium fins for superior oxidation and corrosion resistance
- Optimized for extreme temperature and pressure conditions
Technical Details
HFW (High-Frequency Welded) Construction
The base tube is manufactured using high-frequency electrical currents to create a strong weld with excellent mechanical properties, dimensional accuracy, and cost efficiency.
Solid Finned Tube Design
The integrally bonded fins increase surface area for superior heat transfer while maintaining structural integrity under mechanical stress.
11-13 Cr Fin Composition
The high chromium content provides exceptional resistance to oxidation and corrosion in high-temperature environments, extending service life.
