Function of threaded pipe: 1. In boiler application, after heat exchange and flow resistance optimization, the heat transfer of a threaded pipe is equivalent to 1.7-1.8 ordinary pipe of the same size. This not only makes the number of smoke pipe significantly reduced, but also can reduce the diameter of the pot shell, thus, the pressure component steel consumption significantly reduced, save the steel, reduce the cost. 2. In the application of air conditioning and refrigeration industry, compared with the general smooth light tube, the heat transfer surface area of the light tube is more than 1.5-2.0, which greatly improves the flow mode of coolant and enhances the heat transfer effect of boiling and condensation inside the tube. The pressure loss of the refrigerant is reduced by more than 50% through the internal screw. Manufacturing needs to expand the pipe, welding and other processing technology is the same as the ordinary pipe. Make the air conditioner small and light, compared with the light tube, the weight of the tube is saved about one third. Operation saves electricity and costs. 3. In the application of heat exchange equipment, the steel tube or stainless steel tube is rolled into shape at one time through the machine tool, and the scale on the surface of the spiral tube is in spiral shape. The change of temperature during the operation of the equipment makes the tube expand and contract, so the scale layer can fall off by itself. The smooth tube scale layer is cylindrical, without any self - release force. It has been widely used in power plant condenser and boiler auxiliary heat exchange system, and is an ideal choice to replace light pipe and copper pipe.
