Hi All,
In the current project the project site temperature is below zero degree centigrade.
to provide winterizing to process fluid our p&ids’ show hot water tracing of process lines.
But this is the first time we have encountered this type of tracing.
Can anyone tell me the basic requirements (e.g. Tracer size calculations, no. of tracer calculation, maximum length which one tracer can serve, Supply and Return manifold details etc.) for this type of tracing.

Thank You
Siddharth Jain
