ASTM A213 T5 Embedded G Fin Tube For Heat Exchanger And Air Cooler

ASTM A213 T5 Embedded G Fin Tube For Heat Exchanger And Air Cooler

1. What is ASTM A213 T5 Embedded G Fin Tube?
ASTM A213 T5 Embedded G Fin Tube is a high-integrity heat transfer solution for extreme hydrogen and sulfur environments. It features a seamless chromium-molybdenum alloy steel base tube (ASTM A213 T5, UNS K41545) with spiral G-type fins mechanically embedded into precision-grooved surfaces. This interlocking design achieves 360° metallurgical contact, eliminating thermal resistance while providing unmatched resistance to hydrogen embrittlement and sulfidation up to 593°C (1,100°F). Ideal for hydrocrackers, reformers, and syngas coolers.
