Frequently Asked Questions

What materials do you offer for fin tubes?

We manufacture fin tubes using carbon steel (A179, A192, A210), stainless steel (TP304, TP316, TP310H), copper (C12200), CuNi 90/10, titanium (Gr. 2), and duplex stainless steel (UNS S32205).

What is the difference between extruded and embedded fin tubes?

Extruded fin tubes have aluminum fins mechanically formed over the base tube, offering high thermal efficiency. Embedded fin tubes have fins mechanically locked into grooves on the base tube, providing excellent mechanical bonding and vibration resistance in high-pressure environments.

Do you provide custom fin tube designs?

Yes, we offer full customization including tube diameter, fin height, fin pitch, fin thickness, material selection, and length. Our engineering team supports OEM and project-specific requirements.

What certifications do your products have?

Our products comply with ASTM, ASME, EN10204 Type 3.2, and other international standards. We provide full material test reports (MTRs) and quality documentation.
