    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 industry.
