ASME SA333 Grade 1 High Efficiency Heat Exchanger Low Fin Tube

The Low Fin Tube manufactured from ASME SA333 Grade 1 is a high-performance heat transfer solution engineered to maximize thermal efficiency while maintaining excellent mechanical reliability. By forming low fins directly on the outer surface of the base tube, the effective heat transfer area is significantly increased without adding excessive weight or flow resistance.

ASME SA333 Grade 1 carbon steel is well known for its good low-temperature toughness, weldability, and pressure-retaining capability, making it an ideal base material for finned tubes used in demanding industrial environments. This combination ensures stable operation, long service life, and consistent thermal performance in both low- and moderate-temperature applications.

Low fin tubes are widely used where enhanced heat exchange is required within limited space, offering a compact and energy-efficient alternative to plain tubes.

ASME SA333 Grade 1 is a seamless carbon steel pipe specification intended for low-temperature service. When used as the base tube for low fin tubes, it provides:
