Special-shaped Tube

The advantage of Twisted tubes is that they promote heat transfer through the creation of a continuous swirl flow that constantly disrupts the boundary layer, this way their efficiency can be increased significantly over that of plain tubes. Besides their special shape, the tubes are capable of minimizing the accumulation of deposits making the fouling process very slow, hence the time for cleaning can be extended and maintenance costs will be reduced. The twisted pattern results not only in a stronger mechanical structure but also a vibration caused by the flow is suppressed, so the running of the equipment is much more stable. Higher-performing heat exchangers mean that heat exchangers can be designed smaller, which helps in saving both space and material. In general, twisted tubes provide a dependable way to enhance thermal efficiency, cut down operational costs, and increase the lifespan of equipment used in heavy-duty applications.

Turbulence strips are designed to enhance heat transfer performance by inducing strong turbulence and swirl flow inside the tube. By continuously disrupting the boundary layer, they significantly improve the heat transfer coefficient compared to plain tubes. Their presence also helps reduce fouling by preventing particle deposition on the inner surface. Easy to install and cost-effective, turbulence strips can be retrofitted into existing heat exchangers without major modifications. They offer an efficient solution to boost thermal performance, reduce maintenance frequency, and optimize overall system operation.

The defining feature of the corrugated tube is the periodic wave structure formed along the tube wall. This wave geometry increases surface area and induces secondary flow patterns inside the tube.
