Steam tracing / overheating
Steam tracing / overheating
(OP)
Hello everyone,
I guess this would be some fundamentals but i am new to this and lost on this one, would appreciate some help
I want to steam trace a line in which liquid content flows (158 °Fahrenheit) and i am wondering is it possible for pipe content to be overheated if steam temperature is
(297 °Fahrenheit)?
How is that temperature of steam transferring to luquid content in pipe?

Generally regarding my doubts i have found this in some book but can not really understand it
"Steam tracing cannot overheat the contents of the line that it is protecting because its maximum temperature is that of the incoming steam"

212ºF ..how can you accomplish having that temperature near 158ºF?
To make up the heat lost from the product pipeline, small bore steam pipes, or tracers, are attached to the product line. Heat from the steam passes into the product line and replaces the heat lost. The amount of heat transferred, and therefore the product temperature, can easily be controlled by simple self-acting control systems.
This bold part, how can you control that temperature?
I have long low pressure steam header from which one i am taking steam to steam manifold from which i use steam to heat pipes that needed to be heated (in this case my wash water line)

In reality this is not possible because of the heat loss through the insulation and normally the low power input from what is often a 1" tube on a much larger pipe.
But what that temperature is needs to be calculated based on those parameters (steam temp, steam tube size, pipe size, insulation type, insulation thickness, ambient air temp (min/max) wind speed.
For freeze protection, many location will use electrical trace heating or self limiting electrical trace heating.

Also: If you get a response it's polite to respond to it.

Can you please elaborate this? How lower power affects that
RE: Steam tracing / overheating
In static conditions, eventually heat in = heat out.
If there isn't much heat in then the temperature will gradually fall until the two become equal.
