What is copper finned tubes?
Copper finned tubes are a newly developed type of heat exchange copper tube in recent years, which include copper or cooper alloy tubes and fins.
Copper finned tubes size:
Copper finned tubes size range includes: gdht-b series evaporation tubes and gdht-c series condensing tubes, gdht-brb series and gdht-brc series lithium bromide unit tubes. It is the key heat transfer element of shell and tube heat exchanger. External thread (external fin) copper pipe parameter specification: φ 15.88mm～ φ 25.4mm, 19-60 outer fins / inch, fin height 0.65mm-1.2mm, internal tooth height 0.1mm-0.45mm, bottom wall thickness 0.65mm-1.2mm. (can be produced according to customer requirements or drawings)
Brazed Copper finned tubes
Brazed Copper finned tubes refers to the group of high-quality copper pipe is through a dedicated winding machine, the high-quality copper strip tightly wound evenly on the outer surface of the base pipe, then the whole lining of tin. Around the chip brass copper finned tubes, the working temperature: -10 ℃ - + 160 ℃ Vacuum furnace heat exchanger: The copper Lintong brass brazing process of finned tubes, tube sheet welding a rate of 100%, non-contact thermal resistance, fin folds small, heat capacity, operating temperature 550 ℃.
