Description

Technical Field

[0001] The utility model relates to the technical field of pipes, in particular to a flat wave steel wire outer rib pipe. Background Art

[0002] The external fin tube is a heat exchange element used in tubular heat exchangers. The outer surface of the tube body of the external fin tube is convex in shape. The external fin tube can withstand the impact of external forces. It is mainly suitable for light petrochemical, textile, papermaking and other light industrial fields. Among them, the flat wave steel wire external fin tube also plays an important role.

[0003] The existing external rib tubes have some disadvantages. First, the stability is poor. When impacted, the outer tube exerts a vertical upward force on the inner tube, which can easily cause the inner layer of the tube to crack. Moreover, the cracks are not easy to be discovered, affecting the use. Secondly, the performance is poor, the sound is aged, and the service life is affected. In addition, the rigidity is poor and it is easy to deform. Utility Model Content

The acute angles between the ribs and the outer cylindrical tube body and the inner cylindrical tube body are all degrees. When the outer rib tube is impacted and squeezed from the outside, the impact force is transmitted along the ribs and buffered, reducing the possibility of damage to the inner cylindrical tube body caused by external force, avoiding the rupture of the inner cylindrical tube body, ensuring the quality problems during transportation and use, and improving the stability of the outer rib tube.
