ASTM A106 GR.B Studded Fin Tube with Carbon Steel Pins For Petrochemical

Product Specification

ASTM A106 GR.B Studded Fin Tube with Carbon Steel Pins For Petrochemical Refineries

ASTM A106 Gr.B Studded Fin Tube with Carbon Steel Studs is a high-performance seamless heat transfer tubular solution engineered for extreme high-temperature and high-pressure industrial operating conditions. Combining durable ASTM A106 Grade B carbon steel base tube and solid carbon steel stud fins, this specialized finned tube delivers outstanding thermal conductivity, structural stability, and long-term service durability for diverse heat exchange and heat recovery systems.

Different from traditional spiral or plate fin tubes, our studded fin tube features dense solid carbon steel studs vertically welded on the outer tube surface. Each carbon steel stud acts as an independent heat transfer unit, effectively expanding the heat exchange area and disrupting fluid flow to eliminate heat transfer dead zones. This unique structural design greatly improves heat exchange efficiency, making it far more adaptable to high-temperature flue gas and harsh working environments than conventional fin tubes.
