The Experience Relationship between Fin-height and Rough Tube Wall-thickness for Cold-drawn Outer-spiral-fin Tube

The experience relationship between fin-height and rough tube wall-thickness for cold-drawn outer-spiral-fin tube is established with many-membered Iinear regression in this paper.This relationship can be used to forecast and control the fin-height of the outer-spiral-fin tube,and it has referenced value for the working-out of the technics for cold-drawn outer-spiral-fin tube.
