G Type Embedded Spiral Finned Tube
G-type embedded spiral finned tube is made by machining a steel strip of a certain width and depth of spiral groove on the steel pipe, and then the steel strip is set on the steel pipe by equipment. During the winding process, the steel band will be firmly wound in the spiral groove because the preload force reaches a certain level to ensure a certain contact area between the steel band and the steel tube. In order to prevent the steel belt spring from falling off from the optical tube, both ends of the steel belt need to be welded to the steel tube. In order to facilitate the setting, there should be a certain gap between the steel belt and the spiral groove. If the gap is too small, the commissioning process will be difficult to proceed smoothly.
In addition, there will always be a certain amount of springback in the wound steel strip, which prevents a good bond between the strip and the bottom of the spiral groove. Inlaying fins can be done on general equipment and at a very low cost. Our company adopts advanced production equipment in McElroy Company in the U.S.A. The advanced technology of slotting and pre-embedding, good self-stabilization, firm pre-embedding, pull-off force of not less than 70n, and the permissible temperature of up to 400℃, with strong resistance to temperature and thermal shock, are widely used in petrochemical air coolers.
