Zoom tube:
The telescopic tube is a kind of enhanced heat transfer tube which is composed of the shrinking section and the expanding section.
In the process of advancing inside or outside the tube, the fluid is changed by the expansion and contraction of the surface of the retractable tube, and the heat transfer effect is improved.
This kind of heat transfer tube is not easy to scale and has good heat transfer enhancement effect, so it has a broad application prospect in sulfuric acid and petrochemical industries.
