ASME SA335 P22 Alloy Steel HFW Solid Finned Tube for Refinary Application

ASME SA335 P22 Alloy Steel HFW Solid Finned Tube for Refinary Application

1. Description of ASME A335 P22 HFW Finned Tube

The ASME A335 P22 High-Frequency Welded Finned Tube is a premium-grade heat transfer solution engineered for extreme temperature and pressure conditions. Constructed from ASME A335 P22 alloy steel (a chromium-molybdenum steel renowned for high-temperature strength), this finned tube features helical or longitudinal fins precision-welded using high-frequency currents. The HFW process ensures a seamless, crack-resistant bond between the P22 base tube and fins (commonly steel or corrosion-resistant alloys), delivering unmatched thermal efficiency, durability, and resistance to creep and oxidation. Certified to ASME standards, it is the go-to choice for critical applications in power generation, petrochemicals, and heavy industry.
