1, in the boiler application, after heat exchange and flow resistance optimization, a threaded pipe heat transfer is equivalent to 1.7-1.8 the same size of ordinary pipe. This not only significantly reduces the number of pipes, but also reduces the diameter of the pot shell, thus, the steel consumption of the pressurized element is significantly reduced, saving steel and reducing costs.
2, in the air-conditioning refrigeration industry, compared with the general smooth light tube, more than the heat transfer surface area of the optical tube 1.5-2.0, greatly improved the flow of cold agent, strengthen the tube boiling and condensation heat exchange effect. The refrigerant is pushed by a spiral through the internal thread, reducing its pressure loss by more than 50%.
3. In the application of heat exchange equipment, steel pipe or stainless steel pipe through the machine tool rolling once molding, spiral tube surface scale is spiral, the temperature change in the operation of the equipment line so that the tube expands and contracts, so that the scale layer can fall off on its own; It is now widely due to be made in accordance with customer requirements.
