Threaded pipe
Threaded tube, also known as low rib tube, mainly depends on the tube external ribbed (ribbed coefficient of 2-3) to expand the heat transfer area. Threaded pipe is generally used in the heat coefficient inside the pipe than the heat coefficient outside the pipe more than 1 times the occasion. For condensation and boiling outside the tube, due to the action of surface tension, it also has a good strengthening effect.
