1. Due to the concave - convex shape of the nodular tube surface, a strong turbulent flow is formed inside the tube, which greatly increases the heat transfer coefficient on the inner and outer surfaces of the tube. As a result, the overall heat transfer efficiency of the heat exchanger is 2 - 3 times higher than that of the ordinary shell - and - tube type.

2. The nodular tube has a self - cleaning function through thermal expansion and contraction, so it is not easy to scale.

3. Due to its corrugated structure, it can self - compensate for the thermal stress generated by the temperature difference of the medium.

4. Due to the self - compensation function of the nodular tube, the thermal stress on the tube sheet is small, and there will be no leakage caused by the rupture of the tube mouth, making the heat exchanger safe and durable.

5. Since the clearance between the nodular tubes and inside the tubes is larger than that of the plate heat exchanger, its anti - blocking performance is better.

6. It can adapt to higher operating temperatures and pressures than the plate heat exchanger.

7. During its service life cycle, it incurs a lower maintenance cost.

**Application of the Nodular Tube Heat Exchanger**

It is widely used in chemical industry, petrochemical industry, refining, paint, soap, and heat exchange between steam and water in thermoelectric heating.

When the small - sized nodular tube heat exchanger is applied in some situations, it can be combined with other equipment to form a skid - mounted heat exchange unit.

Heat exchange area of the supplied products: 3m² - 400m² per unit
