ASTM A333 Gr1 Seamless Carbon Alloy Low Fin Tubes For Air Coolers

ASTM A333 Gr1 Seamless Carbon Alloy Low Fin Tubes For Air Coolers

This specification A333 covers nominal (average) wall seamless and welded carbon and alloy steel pipe intended for use at low temperatures.ASTM A333 Gr.1 low fin tubes are specialized heat exchanger tubes designed for air coolers and other heat transfer applications. These tubes feature an externally finned surface to enhance heat transfer efficiency while maintaining the low-temperature toughness required for cryogenic and sub-zero environments.

Chemical Composition (%)

Mechanical Properties

Advantages

Enhanced Heat Transfer – Fins increase surface area for better air-side heat exchange.

Low-Temperature Toughness – Suitable for sub-zero applications, with excellent impact resistance at low temperatures.

Cost-Effective – More efficient than bare tubes, reducing equipment size.

Application ( Not limited to the following )

Air-cooled heat exchangers (ACHEs)

Process cooling in refineries, petrochemical, and LNG plants

Low-temperature heat transfer (down to -45°C / -50°F)
