What is extruded fin tube?
Aluminum extruded finned tubes, also called “integral finned tubes” using the form of the base tube covered with aluminum tube(the base tube can be carbon steel, stainless steel, copper) through machine extrusion, forming a tube fin, the fin base and the tube outer wall is close fitting, this fin tubing control can make finned tubes with high heat transfer coefficient and heat transfer performance.
Extruded finned tube can be made of iron, copper or aluminum tube by compound rolling, which has the advantages of tight bonding, small thermal resistance, good heat transfer performance, high strength, small flow loss, strong anti-corrosion performance, not easy to deformation under long-term hot and cold working conditions, long working life and so on.
Advantage of extruded fin tube
Compared with the ordinary fin tube, the contact thermal resistance remains stable in a large range with the temperature change, so the heat transfer performance of the bimetallic aluminum extruded finned tube is better than the spiral fin tube in the limit tube wall temperature range.
In addition, compared with the coiled tube, the bimetallic aluminum extruded fin tube has outstanding corrosion resistance and high strength, it can withstand 4.0MPa water pressure cleaning, the fins still do not fall down, the base of the bimetallic aluminum extruded tube.
The tube can be selected according to the corrosion of the fluid in the tube and the processing technology. The base tube can be carbon steel, copper, stainless steel, etc.
B163 is a standard that specifies the requirements for nickel-based alloy pipes and tubes.
N08825 is the UNS (Unified Numbering System) designation for a specific nickel-chromium-molybdenum alloy, commonly known as Inconel 825. This alloy is known for its excellent corrosion resistance and high-temperature strength, making it suitable for various industrial applications.
