 Welded Spiral Finned Tubes With Serrated

Serrated Finned Tubes short for High Frequency Welded Helical Spiral Serrated Finned Tube

Helical serrated finned tube, the serrated fin is a metal strip that has been serrated or cut and then helically wound around the base tube. Others are same as high frequency welded solid fin pipes.

The important features of this configuration are efficient, effective bond of fin to tube under all conditions of temperature and pressure, and ability to withstand high fin side temperatures. This serrated fin configuration is even better to withstand the fin fouling if that is a problem in the application. This gives better heat transfer properties compared to solid fins
