Regarding heat tracing
Thread Content
Chemical plants in the north always use a large amount of heat tracing as a insulation measure. First, do you have any good suggestions regarding the layout of the heat tracing? Second, how should the dripping water from the heat tracing be managed?
Our company uses both steam and electricity for heat tracing, but not in large quantities. Generally, the issue of possible heat tracing needs to be considered when installing piping and equipment. The condensate from steam tracing is used as make-up water for the circulating water.
If steam tracing is used, then steam traps should be considered as drain points; generally, national standards require a distance of 30–50 meters between such drain points
Received, thank you for the learning!*
Firstly, do you have any good suggestions regarding the layout of heating systems? Heating systems are often a source of trouble; most of them are integrated into the insulation systems, which makes the flow processes difficult to manage. Therefore, it is essential to plan the heating systems carefully during both the design and construction phases. Centralized supply and return valve assemblies can be used, and electric heating can replace some steam-based heating methods. Secondly, how should the backflow dripping from the heat tracing be managed? Leaks at the sealing points are either due to inadequate maintenance or quality issues with the valves themselves; it is recommended to choose valves of high quality during installation, and to pay close attention to the maintenance of the packing. Additionally, other forms of heat tracing can be employed.
Steam tracing provides a higher temperature, while electric tracing offers more even heating; it depends on what type of pipeline is being used and whether there are instruments installed on that pipeline.
