What is Cheaper for Duplex 2205 Pipe, Sch. 5 or Sch 10 ?
(OP)
Dear alls,
I have to buy Duplex Pipes for Gas/Air service With Diam Range: 2" - 16".
I think Sch 10 is cheaper than Sch 5 (My boss wants to buy Sch 5).
What do you think ?

IMHO, the schedule 5S piping will require much more expensive pipe suppports than the 10S..... This will be especially true with large diameter (heavy support loads) and higher temperature duplex piping.
Competent pipe-support designers know that many 5S supports will require pads to distibute sysem loads.
Heavily loaded riser supports on piping systems may require full encirclement reinforcement.
Elbow trunions are, IMHO impossible

Duplex is usually only required for highly corrosive fluids and not what sounds like utility piping. I fully agree that you can go too thin sometimes and just because a material seems to be avilable, doen't mean that overall it will be the cheapest - just makes it difficult to justify some times which is what I think th eOP is looking for. Still not clear why he's chosen duplex though...

Answering your Questions; The process involves NaOH , N, NaSH and other corrosive fluids. Besides the temperature ranges is: 113° F - 230° F, that's why we have to ues Duplex instead of Reinforced Fiber Glass.
I don't have the certainty, but I think 5S is not Std as other Schedules as TomDOT mentioned above.
Obviously the only way to know is getting some Quotes, but the vendors responses likely takes time and standards desviation..etc that's why I ask for some help in this issue.
