Spiral wound tube heat exchanger products include: spiral wound tube heat exchanger, detachable, and corrosion-resistant. This type of heat exchanger has good turbulence effect, high heat transfer efficiency, low probability of impurity deposition, and low tendency to scale. The spiral winding structure completely eliminates the pulling force between the heat exchange tube and the tube sheet, greatly improving the service life. Under the same heat exchange capacity, the volume is about 1/10 of traditional heat exchangers, which can save valuable space resources. Advanced technology, sophisticated equipment, comprehensive testing system, and down-to-earth heroic people have created the excellent quality of spiral wound tube heat exchangers, with cost-effectiveness far higher than similar products. Compared with traditional heat exchangers under the same operating conditions, the investment is almost the same, but it can save a lot of operating costs for enterprises every year, which is highly favored by users. Spiral wound tube heat exchanger, also known as threaded tube wound heat exchanger or spiral threaded tube heat exchanger, is a representative work of the new heat exchange products. Mainly applicable to vapor-liquid heat exchange conditions, it is designed based on CFD computational fluid dynamics technology, FEM differential finite element technology, OWEN turbulent oscillation frequency criterion, Eisinger criterion, Bevinsbbb criterion, asymmetric flow design and other techniques. At present, the highest heat transfer coefficient in steam water heat exchange conditions can reach 14000w/㎡ ℃.

The heat exchange tubes of conventional shell and tube heat exchangers are designed using straight or U-shaped tubes. So a question that troubles design engineers is what method can be used to make the heat exchange tube longer, increase the heat exchange area per unit volume, and fundamentally maintain the heat conduction in an ideal state due to the structure of counterflow heat exchange. At the same time, the volume of the heat exchange equipment itself needs to be reduced, and the safety performance needs to be stronger. The successful development and gradual improvement of spiral heat exchange tube bundle winding technology have fundamentally solved this problem.

Different from conventional straight tube heat exchange tubes, the arrangement of heat exchange tube bundles in spiral wound tube heat exchangers is based on the number of tube bundles in each layer, and the same angle is wound in reverse. The tubes are evenly distributed inside the heat exchange tube shell and maintain reasonable tube spacing and layer spacing. The result of this is not only that the heat exchange tubes are lengthened, but also that there are sufficient processes for material circulation and heat exchange, while maintaining pressure balance of the fluid in the shell side and evenly distributing thermal energy. In practical use, this greatly improves heat transfer efficiency and capacity.

Material processing

The most ideal state for the treatment of wrapped heat exchanger tube bundles is that, while reasonably balancing the hardness and plasticity of the tube bundles, there will not be excessive stress points.

Our material treatment perfectly embodies this requirement.

Accurate spacing between heat exchange tubes

Stainless steel pipes are difficult to plasticize during bending or winding due to material issues, and it is necessary to maintain uniform spacing between all heat exchange pipes. This requires us to have complete technology and rich experience in processing. The high-precision equipment imported with original equipment and top-notch winding technology provide us with a foundation.

Reasonable number of pipe layers and interlayer spacing

When winding the heat exchange tube bundle, it is difficult to ensure that the length of each heat exchange tube is basically the same because the relative diameters of each layer are changing and the winding angle needs to be consistent.

The company has designed different numbers of heat exchange tubes for each layer, as well as reasonable interlayer spacing, to perfectly overcome this problem and also solve the flow channel requirements under complex heat transfer conditions.
