Wholesale Cold Drawn Steel Tube – China High Quality Threaded Pipe – Wald Detail:

Threaded pipe is a kind of spiral heat conduction pipe with inner convex and outer concave on the pipe wall. Since the publication of the first academic report of boiler threaded pipe in 1966, threaded pipe has attracted great attention as an efficient heat exchange element. At present, it has been more and more widely used in China.

Application

In the application of air conditioning and refrigeration industry, compared with the general smooth light tube, the heat transfer surface area is more than 1.5-2.0, which greatly improves the flow mode of refrigerant, and strengthens the boiling and condensation heat transfer effect in the tube. The refrigerant produces spiral propulsion through the internal thread, reducing its pressure loss by more than 50%. Manufacturing needs to expand pipe, welding and other processing technology is the same as ordinary pipe. So that the air conditioner is small and light, compared with the light tube, the weight of the pipe can be saved about one third. Operation saves electricity and cost.

In the application of heat exchange equipment, steel tube or stainless steel tube is rolled once by the machine tool, the scaling on the surface of the spiral tube is spiral, and the temperature change in the operation of the equipment makes the tube expand and shrink, so the scaling layer can fall off by itself; The scale layer of the light tube is a cylinder without any self – stripping force. It has been widely used in power plant condenser and boiler auxiliary heat exchange system and is the ideal choice to replace the light tube and copper tube. Threaded tubes (twisted tubes or patterned tubes) used in arts and crafts, such as the yellow argyle handrails in passenger cars, are new examples.
