Stainless Steel Hemp Tube

The pit/convex structure of the pit tube not only enhances heat transfer without excessively increasing the pressure drop, but is also less likely to generate dirt and dust, reducing wear on the tube wall, and it also has a certain pressure-bearing strength.

Due to the existence of periodic convex cells on the inner surface of the hemp tube, the steam motion state changes, aggravating the fluid disturbance and thinning the boundary layer. At the same time, the synergy between the steam side velocity field and the temperature field is improved to achieve enhanced heat transfer on the steam side.

A pitted heat exchange tube, including a tube body formed by bending and welding metal strips, characterized in that the outer surface of the tube body is provided with a plurality of convex pillars arranged at intervals, and each of the convex pillars respectively includes: The column body is formed by protruding from the outer surface of the pipe body along the radial direction of the pipe body. The cross section of the column body perpendicular to the radial direction is rhombus, and the rhombus shape A diagonal line is parallel to the axis of the tube body; and a column cap, the column cap is integrally formed on the top of the column body, the column cap includes: overlapping with the top in the radial direction an overlapping portion, and an extension portion integrally surrounding the overlapping portion.

Purchasing cost lower full range of O.D. widely applied.

Besides the specifications in the table above, tubes can be manufactured according to customers'requirement or drawings.
