Gas pipe design

[lola.furtado]

Hi guys! I'm a student working on a class proyect and i have two questions:

I have to design a gas pipe. ¿Should i use a maximum temperature or a minum one? ¿Why?

Sorry if it's the wrong forum!
Please help me, thank you!!

What kind of gas? What kind of pipe? Do you have a design code? How long is the pipe?

Design temperature is important, but we're going to need a lot more detail from you.

you'll probably need to consider both ... why ? (we can tell you, but you'll learn better if you discover it for yourself).
