New name for 2" IPS copper tubular bus

[Beengineer]

In the new standard, there are two types of 2" copper substation tubular buses - 2" copper, schedule 40, 98%ICAS; and 2" copper, Schedule 80, 98% ICAS.

Which one is equivalent to 2" IPS Copper in the old standard?

Thanks

Because of its thinwall construction, copper tubing is smaller than IPS pipe. That distinguishes CTS (Copper Tubing Size) from IPS (Iron Pipe Size).
If you meant the cross correspondence between 2" CTS Standard and 2" ASTM B-188 then no type is accurately correspondent.
Type K [CTS] is close, in a way, to schedule 4 but the outside diameter is only 2.125[CTS] with respect to 2.375[ASTM B-188].
The wall thickness is 0.166 for CTS and only 0.156 for ASTM B-188.

IPS is Iron Pipe Size.
I have always assumed Iron Pipe Size to be schedule 40 unless otherwise stated.
Iron, Copper or Aluminum.

I also got a source called IPS "Internal Pipe Size".

It'll have the completely different meaning from "Iron Pipe Size".

Can someone to verify it?

Thanks

Or Ingress Proection System.
For schedule 40, IPS equals IPS mostly.
But there are exceptions where the internal diameter of a schedule 40 pipe does not match exactly the nominal Iron Pipe Size.
An excerpt from the following link:

Regardless of schedule number, pipes of a particular size all have the same outside diameter (not withstanding manufacturing tolerances). As the schedule number increases, the wall thickness increases, and the actual bore is reduced. For example:

* A 4 inches (100 mm) Schedule 40 pipe has an outside diameter of 4.500 inches (114.30 mm), a wall thickness of 0.237 inches (6.02 mm), giving a bore of 4.026 inches (102.26 mm)
