Stainless steel clean steam piping design guidelines???
Stainless steel clean steam piping design guidelines???
(OP)
Can anyone point me to a reference for the specification of a stainless steel piping system for a 65 psig clean steam system?
I've already done the design including pipe sizing, traps, etc. What I need is information on recommended pipe schedules, if tubing is more appropriate than pipe, etc.
The material will be 316L to prevent corrosion and rouging.
The steam is generated from deionized water.
Thanks

t = f * P*D/(2*S)
t = wall thickness (inches)
f = safety factor
P = internal design pressure (psi)
D = outside diameter
S = allowable stress for your material at your design temperature (psi). For stainless steel ASTM A312 TP316L the value of allowable stress is 16700 psi (roughly)
Then, when you get the pipe thickness from the formula above, you can easily find the pipe schedule suitable for your application.

What I'm looking for more specifically is a guideline(s) relating to standard industry practice. For instance, I could use tubing (of differing wall thicknesses), schedule 10, or schedule 40 piping, etc.
Are there cost or availability issues that need to be considered? Installation issues?
Since tubing is thinner than piping, are there erosion issues that could come into play?
Thanks

In my experience, the mill tolerances and corrosion thickness requirements for the piping are more than the thickness needed for the pressure, e.g. for 150# steam the tube only needs to be the thickness of paper for 2" pipe. However, vacuum pressures also could be a factor, otherwise the system will collapse when it cools off.

What is the steam to be used for?
