Temperature issue with steam pipeline pressure guide tubes (urgent!)
Thread Content
The temperature of the main pipeline is 370 degrees; what is the temperature of the pressure guide pipe after passing through the condenser tank? (Pressure variation): What temperature resistance should a heat-tracing cable have when selecting one? Do all the sea friends know clearly?
Within the pressure guiding tube, there is almost no flow of the medium while it is in operation; heat rises, and it cannot pass through the high points (the areas where the tube is in an inverted U shape). Therefore, during normal operation, the temperature of the pressure tap pipe in thermal pipelines is considered to be based on the temperature of the medium within the equipment at the first highest point after the pressure tap (which may be the pressure tap itself), and thereafter it is considered based on the ambient temperature.
