There used to be a standard called GBT9711.2-1999, which specified recommended wall thicknesses. Now there is GBT9711-2011; it seems that this standard replaces the 1999 version, but the new standard does not include any recommendations regarding wall thicknesses at all! According to the design firm, they are still referring to the old standards when choosing the wall thickness? The image is the old standard

Also, let’s discuss whether this wall thickness notation, sch80, should be phased out

Why is sch80 being phased out? We still use it today. Can’t we use SH/T3405 or HG 20553 for the wall thickness of oil and gas pipelines?

I feel these two specifications are not appropriate. . . Sch indicates that the wall thickness needs to be looked up in a table, which I find not very convenient
