Use of Schedule 40 pipe for structural supports terminology

[Whoosh7953]

Few questions below:

Can the term use of Schedule 40 Structural steel pipe be used interchangeably when discussing structural steel supports for construction?

Does refering to it as a pipe and not a post or column signify that the terminology is wrong? Can pipe be used as a relative term?

Is HSS A500 structural steel round pipe usable for structural support applications?

If discussing structural support and you say for example; we could use schedule 40 structural pipe, instead of saying we could use a structural column, structral tubing, structural post without any actual materials or shapes being specified would that be ok if not caught up in the semantics?

Keep in mind this is just about the word pipe being used as the terminology instead of tube, column, post, because the argument from a coworker is that schedule 40 structural pipe is only for water or gas piping and does not exists for structural support so the terminology I was using is incorrect. Also keep in mind that the assumption is that we would be using A500 not A53 pipe which I believed could be used for structural support under certain conditions. Please help me either understand if I'm wrong or send me back up to educate my ignorant coworker.

Thank you

I think you could call it whatever you want if you're specifying an ASTM standard. However, I believe the correct terminology would be "structural tubing" if specifying per A500, and "pipe" if specifying per A53. Pipe used for structural applications is typically designated as standard (STD), extra strong (XS) or double extra strong (XXS), rather than by schedule, which indicates a pressure rating.

I generally call it up as:
-PIPE TO CONFORM TO ASTM A53 GRADE B TYPE S MIN.

I generally don't use ASTM A500C, but if I do, I calculate properties reduced to the min dimensions and wall thickness; these are poor for A500. I generally spec ASTM A1085 in lieu of A500.
