RE: Flange Schedule Selection
What is the corrosion allowance?
What is the design pressure?
What is the design temperature?
Where is the material class for the job you are working on?
RE: Flange Schedule Selection
2) Design Pressure: 120 Bar
3) Design Temperature: 80 Dec C
4) Corrosion Allowance: 0mm

Design pressure – You shall use in the thickness formula that you would be using.
Design temperature (or maximum operating temp) – would be used to select the allowable stress for the thickness calculations.
Corrosion allowance (and other allowances such as mill tolerance) shall be added to the pressure design thickness that you would get from your calculations.
And brother, normally we use the material classes for any job pipe material, schedule (thickness), corrosion allowance, type of welds, applicable code, pressure and temperature limits, flange ratings are mentioned. Check from your group.

Pls help me to understand how to find the thickness of pipe to be used..Many thanks
