What Tests We Should On Heat Exchanger Fin Tubes?

 Finned tube is a heat transfer element of heat exchanger (air cooled heat exchanger, air fin fan cooler and air preheater). With fins added on based tube, increasing the tube outside area, then the heat transfer efficiency improved.

When customer placed the order of heat exchanger fin tubes, ranging from SA179 seamless fin tube, helical spiral crimped fin tube, high frequency solid welded fin tube, stainless steel fin tube, etc), they require a series of test as below:

Heat Transfer Efficiency Test

Fin Tube Characteristics Test

Pulling Tensile Test

Anti-corrosion Test

Surface cleaning test

Anti-dusting ability test
