1. What is ASME SA209 Type G Embedded Finned Tube with Aluminum 1060?
The ASME SA209 Type G Embedded Finned Tube with Aluminum 1060 is an advanced heat transfer solution engineered for high-temperature and high-pressure environments. It features a seamless carbon-molybdenum alloy steel base tube (ASME SA209 Grade T1/T1a) with Aluminum 1060 fins (99.6% pure aluminum) mechanically embedded into precision-machined grooves on the tube surface. This innovative "G-Type" design ensures a secure, gap-free bond between the base metal and fins, combining the high-temperature strength of SA209 steel with the lightweight, ultra-high thermal conductivity of aluminum. Ideal for boilers, superheaters, and corrosive industrial systems, it delivers unmatched efficiency, durability, and corrosion resistance.
