What is ASTM A179 embedded fin tubes?

The G type embedded spiral finned tube is processed from a specific width aluminum strip and spiral groove depth, then the equipment inlays the ribbon on the ASTM A179 tubes. In the winding process, as the pre-tightening force to a certain extent so that the strip is firmly in the spiral groove, to ensure a certain contact area between aluminum band and ASTM A179 tubes. To keep the strip spring from falling off the light tube, weld the two ends of the steel strip to the steel pipe. There should be some space between the steel belt and the spiral groove for it to set easily. The setting process will be difficult to complete if the clearance is too small. Furthermore, the steel belt of winding will always have some rebound, preventing a very good joint between the steel belt and the spiral groove bottom. Inlaid fins can be performed with standard equipment and at a low cost. McElroy companies in the United States I used advanced production equipment, slotting embedding technology is advanced, from stable, embedded, and firm, pulled off force not less than 70N, allowable temperature can reach 400 °C, has strong temperature resistance and thermal shock ability,widely used in petrochemical air cooler.
