Product Description

Product synopsis:

Since the U.S. Luwsun et al., in 1966 published the first academic paper of threaded pipe, threaded pipe as a kind of high efficient heat transfer element has attracted great attention. At present in our country also got more and more widely used. Threaded pipe is a kind of concave convex outside inside the spiral heat pipe, equipment adopts the method of cold rolling the ordinary light pipe into thread.

Second, the advantages:

1, the application in the boiler, the optimization of heat transfer and flow resistance, a thread of smoke tube heat transfer is equivalent to 1.7-1.8 - the root of the same size of ordinary smoke tube. This not only make the pipe number decreased significantly, but also can reduce the diameter of the pot shell, therefore, pressure parts of steel consumption significantly reduced, saving steel, reduce the cost.

2, in the application of air conditioning refrigeration industry, compared with the general smooth light pipe, more than the light tube heat transfer surface area of 1.5 2.0, greatly improve the refrigerant flow mode, to strengthen the tube boiling and condensation heat transfer effect. Spiral propulsion refrigerant through the internal thread, the pressure loss to reduce more than 50%. Manufacturing needs expansion pipe, welding processing technology such as the same as the common pipe. Make the air conditioner small, lightweight, compared with light tube, pipe weight to save about a third. Save electricity and save cost.

3, in the application of heat exchange equipment, steel or stainless steel tube through a molding machine rolling, spiral tube surface fouling are spiraling, equipment operating line as a result of the change of the temperature in the tube expansion and contraction, thus can make the dirt to fall off; For the cylinder and the light pipe scale layer, without the power off. Has now been widely should be in power plant condenser and boiler auxiliary heat exchange system, it is the ideal choice to replace the light pipe and copper pipe.

4, threaded pipe can also be used for arts and crafts, jinlong bus in yellow argyle armrest is new application example.
