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.
