Tin brazed copper finned tube and Phosphorus-copper brazed finned tube with copper tube have 100% weld rate, no contact thermal resistance, small fin wrinkle, large heat transfer capacity, and working temperature of 550℃.

Application: mainly used for a heat exchanger of vacuum furnace heat exchanger.

with advanced production equipment, finned tube gas protection brazing furnace production equipment and technology, professional production and processing of various types of finned tube, heat pipe heat exchanger components and products, strong technical force, strict management, reliable product quality, and reasonable price concessions

Phosphorus-copper brazed finned tube with copper tube has 100% weld rate, no contact thermal resistance, small fin wrinkle, large heat transfer capacity, and working temperature of 550℃.

Brazed finned tubing offers a seamless metallurgical bond between fin and tube. Seamless metallurgical bond results in this type of attachment being ideal for rigorous, high-temperature applications. When the temperature rises or falls the tube expands or shrinks due to the temperature never relaxing its grip. Brazed finned tubing in similar or dissimilar metals for increased heat transfer efficiency. the bond created between the tube and the fin ensures a stress-free, uniform, and non-porous contact. this bonding allows for thinner tube walls compared to a welded fin to the tube.
