ASTM A213 TP316L Embedded G Fin Tube With Aluminum 1060 For Refrigeration And Air Conditioning Systems
1. What is ASTM A213 TP316L Solid Fin Tube with Aluminum 1060?
The ASTM A213 TP316L Solid Fin Tube with Aluminum 1060 is a premium heat transfer solution engineered for extreme corrosion resistance and high thermal efficiency. It features a seamless low-carbon stainless steel base tube (ASTM A213 TP316L, 16-18% Cr, 10-14% Ni, 2-3% Mo) integrated with solid Aluminum 1060 fins (99.6% pure Al) through an advanced extrusion process. The fins are mechanically bonded to the tube surface, forming a seamless, monolithic structure that eliminates air gaps and maximizes heat transfer. Ideal for hygienic and aggressive environments, this design combines TP316L’s chloride resistance with Aluminum 1060’s ultra-high conductivity (235 W/m·K), delivering unmatched durability and performance.
