Integral Low Fin Tube - ASTM A334 Gr.1 Low Temperature Carbon Steel for Enhanced Heat Transfer

Description:

Integral low fin tubes are manufactured by cold forming the outer surface of a seamless tube to raise low fins directly from the base metal. Since the fins are integral with the tube wall, there is no contact resistance, ensuring excellent thermal efficiency and mechanical strength.
ASTM A334 Grade 1 low-temperature carbon steel tubes are designed for enhanced heat transfer in condensers, air coolers, and heat exchangers operating under low-temperature and moderate-pressure conditions.

Fins Type:

• Integral low fins (formed from tube wall)

• Typical fin height: 1.0–1.5 mm

• Fin pitch: 19–26 FPI (fins per inch)

• Custom dimensions available

Material:

• Base Tube: ASTM A334 Grade 1 Low Temperature Carbon Steel

Chemical Composition of ASTM A334 Grade 1
