How is the wall thickness class for pressure pipelines determined?

Thread Content

How can I determine the pressure rating I need using the chart that lists SCH10, 20, 30, 40, 50, 60 up to 160? For example, for a pipe with DN200 and a design pressure of 5.0 MPa, how is it determined which SCH code it belongs to? Thus, find the wall thickness of the pipe in the reference table?

The number following SCH represents the pressure, in units of bar
