What pipe to use for steam

[Portable Welder]

I have a customer that is asking me what type of pipe to order for steam, I told him that I think Grade 106 Type B sch. 80 is the norm.

We use A53B sch40 for 125psi & down and A106 sch40 for higher pressures. We use sch80 for condensate return.

on pressure and tempature. ref: ANSI / ASME B31.1 Power Piping
