Manufacturing Process:
Inner Grooved Low Finned Tubes are ordinary heat exchange tubes that are rolled to form threads on the inner surface, and the
fins are rolled out from the outer wall of the plain tube through rollers. A high-efficiency heat exchange tube type with tubes
and fins in the same tube.
Delivery conditions:
The tube ends are square cut, free of burrs, dry and blown clean on the inside and varnished on the outside.
Put desiccant in each package for continental shipping.
Quality Test:
The integral low fin tube quality is assured by hydrostatic or pneumatic tests, eddy current tests & MARCO tests in order to
verify design specifications.
Acceptance ceritia:

Features of Inner Grooved Low Finned Tubes
⑴ low processing cost;
⑵ wide application. It has a strengthening effect on the evaporation, condensation, gaseous heat transfer and liquid heat transfer
of the shell-side medium;
3. The inner surface area is 1.5-2 times that of ordinary pipes, and the thermal conductivity is 1.5-2.4 times that of ordinary
pipes of the same size. The flow resistance is only increased by 3%-5%, saving 20%-35% of energy, reducing
Air conditioner weight 10%-25%.
