Can the heat-traced pipes share a single drain valve? Why?
No, one for heat tracing and one more! Affects the heat tracing effect! Excess condensate cannot be drained in a timely manner
Several parallel heat tracing pipes that originate from the same gas source can also be combined, and a steam trap can be installed on them – this is suitable for heat tracing pipes in which the condensate flows downward due to gravity.
In fact, this problem arises because when the temperatures before and after the steam trap are normal, it is not possible to prove that heating is available in each pipeline. It is necessary to be able to detect the temperature of the heat tracing pipeline at a point far enough from the drain trap along that pipeline.
One with a ! If a valve is used, you cannot ensure that all pipelines drain simultaneously; what might happen is that steam is discharged along with the water, which would be counterproductive
If you have any issues with steam traps, feel free to consult me. Gansu Hongfeng 920 is the largest steam trap manufacturing base in China, with over 30 years of experience in producing steam traps

Regarding your question, it is recommended that you follow Figures 6.5.2-3 and 6.5.2-4 of the \"SHT 3040-2012 Code for Design of Pipelines, Companion Pipes, and Jacketed Pipes in Petrochemical Industries\" when making the arrangements.
