Extruded Fins / Extruded serrated Fins
Finned tube is composited with iron-aluminum or copper-aluminum tube rolling out the fin, which feathers are tightness, small heat resistance, good heat transfer performance, high strength, small flow losses, strong corrosion resistant performance, not easy to deformation and a long working lifetime in cold and hot condition,etc.
The fin givescomplete protection to the base tube and is much stronger than the applied type due to work hardening of the fin material during the extrusion process.
The inspector should carry out visual inspecton of the finished finned tubes at 10% random rate,the tubes should be clean with no residue left from the finning process and no swarf between them.
The dimension inspection for finished finned tubes should be conducted in accordance with fin tube drawing.
At 10% random rate, the inspection contents are overall length, finned length, bare end length, middle bare tube length, fin tube out diameter, fin heigh, fin thickness , fin pitch, all measureed values for dimension should beaccording to the drawing.
