standard & specification

inner finned tubes

inner fin tube has high efficient extends surface in heat exchanger tube, improving heat exchange property by strengthening heat transfer in the tube, Inner fin is corrugated and the coefficient of heat transfer and can be increased 7~8 times comparing with bare pipe. The inner finned tubes is made of tube and fins by nickel brazed welding with 100% welding rate.
inner finned tubes is able to improve more than 7 times in heat transfer area, also with good shock resistance and high strength, while its volume is much smaller which make cost much down in produtions of heat exchanger and usage by big down in circle water.inner finned tubes

Out tube OD 28mm

Inner tube OD 14mm
