不锈钢伴热管又称预制伴热管,伴热对象多为烟气、导压管、调节阀等,作用是防止管内液体低温下黏度增大，增加动力损耗;防止管内气体带液冷凝,起到安全作用，防止管送液体或浆料凝固导致管线堵塞,起到设备维护作用。

Stainless steel heat trace pipe is sometimes called prefabricated heat trace pipe, and the objects to be heat traced are mostly flue gas, pressure guiding pipe, regulating valve and so on.Stainless steel heat trace pipe works as follows: to prevent the viscosity of the liquid in the pipe from increasing at low temperatures, thereby reducing power loss;  to prevent the gas in the pipe from condensing with liquid and play a safety - ensuring role;  to prevent the liquid or slurry in the pipe from solidifying and leading to pipeline blockage, playing a role in equipment maintenance.
