Service Temp for LTCS pipes
Service Temp for LTCS pipes
(OP)
1)What's the temp limit for normal CS pipe & LTCS pipe?
2) Is the temp limit for product inside or pipe temp.?
3) What if the ambient temp swings from 50*c to -25*C.
Will it be required to go for LTcs for all cases or
need surface insulation?

RE: Service Temp for LTCS pipes
1). Review ASME B31.3 - section 323.3. You can look at figure 323.2.2A for various curves, which are based on material composition.
For no impact testing -
CS, -20 deg F
LTCS is lower than above with no impact testing.
2). Pipe metal temperature.
3). You need to perform a thermal displacement analysis and suitability for cyclic service, again review B31.3.
