<shedule of pipes??>

hi everyone,

i have a question regarding schedule of pipes.
can anyone tell me what 16"-P-1412-A1A means.

thanks.

Looks like a line number to me

16 inch size

P describes the service

1412 is a unique number assigned to that line

A1A is the pipe specification

Check out the pipe spec for the project and that will tell you what schedule pipe it is

still on "A1A" pipe spec.
is this standard <ie..asme/ansi>?

sorry for asking such basic question for im just new in piping design.

You need to go to one of the senior designers and ask him for a copy of the Piping Spec, follow the index to A1A and read. It should give you all the information you need. You should have been given a copy of the spec already as it is a basic requirement when working on projects.
