Pipe Schedule vs Material
Pipe Schedule vs Material
(OP)
How is the pipe schedule and the material related. If I specify 2 1/2" schedule 40 carbon steel pipe - do I still have to specify the material? Or is saying 2 1/2" ASME SA-106 sched 40 pipe redundant?





RE: Pipe Schedule vs Material
When you state "ASME SA106" instead of "carbon steel" you are being more specific.......you are specifying a high-quality grade of seamless carbon steel. Other grades of carbon steel pipe, such as SA53 - Grade B and others could be substituted
(By the way, you should specify the grade of SA106 that you want......SA106 Grade "B" is in most common usage)
By "pipe schedule" make sure that there is no misunderstanding about what you mean...... to me, pipe schedule means wall thickness ( i.e. schedule 40 or 80 etc)
The words "line specification" or "line class"are commonly used to specify all of the materials and pressure ratings used in a particular piping system.
My thoughts only.....hope that this helps

4" PIPE, sch.40 SMLS, A105-B, PE
I call out for 4" diameter pipe, that is schedule 40 thickness (0.237") and it's seamless (SMLS) or ERW (elect. resistance welded) or DSAW (double submerged arc welded) and so on, next is the ASTM type of material ...in this case A53 grade B, and lastly ...the type of end on the pipe ...PE (plain end) BE (bevel end) TE (thread end)
Note here Mr. Zulu53 is correct, material and schedule are related when your looking at pressure/temp. ratings. I am only addressing the way to properly call out pipe in a bill of materials. Hope this helps, Good Luck! ...Mark
