Pipe pressure class

[nondimensional]

I have a PCCP pipeline profile drawing showing pipeline pressure class as 100-6, 150-10, etc. I understand the first number is a pressure class. As in 100-6 means 100 psi pipe. But what does the second number mean - 6?

No idea about it.
Can you share the highlights of the drawing for it?

Might be amount of reinforcement.

Check if it relates to diameter, wall thickness etc.

This might be a project specific numbering system.

I didn't think concrete pipe went up that high in pressure.

Could be the indication of PN value, e.g. PN6, PN10?

I figured out that this was depth of cover. Thanks for all the input. Appreciate your responses.

PS: That was project specific numbering system.

Very strange.
