Steam Supply Mains - alternate pipe materials

anybody know of a viable alternative to black pipe for 4" steam mains at 40 psi? Job is approximately 1,000 feet of pipe and I am getting push back from the "owners friend" about modern materials.

    Quote them on 304 or 316 stainless and see how modern they really want to be.

    "You can have any type of material you want as long as it's black steel." Apologies to Henry Ford. What their issue with "modern materials"?

    That would be interesting, of CPVC is rated for hotter water.

    Even better go for 316L. Did anybody mention black steel?

    How about transparent aluminum?


    It sounds like the OP wants to use black iron but the owners friend is claiming it's outdated, or something.

    Didn't Dan have a story in one of his books about a steam boiler piped in PVC?

    Will the steam be on all the time? If not 1000 feet of steel will move.

    I'd hope someone would put in some swing joints if you are talking 1000' long run.

    Thanks for the input. The owner has a "friend" like my wife has a designer "friend. Great half thoughts without any accountability for results.
    I sent in the job using steel, it was approved by the National office and is going on the books for the late spring.
    Never hurts to ask, despite how foolish the question is.
    Keep busy and keep warm.

    I just thought of a more modern material that may be less expensive and easier to install. Called ductile iron.It's not iron but cheap steel lined inside with some sort of cement.Was popular for municipal water in the seventies.I forget how it was joined.Neither welded nor threaded.It may be flexible enough to snake for thermal expansion.No idea if it was ever tested for steam temperatures.

    Love the responses! Although any austenitic stainless is terrible when thread forming (cold work hardening) so don't forget to quote them with welded joints. If you want to quote them with modern material try Incoloy 800 or Inconel 625, tell them it will do wonders for their possible creep failures in the future. Don't forget to quote the pre and post heat TIG welding.
