Schedule 80 or 40
Schedule 80 or 40
(OP)
Hello,
I'm working about on-shore fiscal counting system design. The whole of my pipes and devices are classed ANSI600. My pipes are in carbon steel A105.
I would like to avoid to calculate for each diameter, the thickness.
In Industry, Schedule 40 or 80 is often chosen.
Could use one type of these classifications to qualify my pipes?
Must I really check each thickness?

RE: Schedule 80 or 40
For ANSI 300 its sch 40 for 12 inch and smaller, sch 80 above 12 inch.
For ANSI 150 its all sch40
This is for accounting estimates, you can get into details about temperatures, company policies, corrosion allowance, but to make it simple. In my industry we have a lot of ANSI 600 lines, but 99% of the vessels in our systems are rated under 1100 psi, so we use sch40 6" and 8". This would make piping guys cringe.
