Could you please help explain what A, B, and C are? Thank you

A is a control system diagram; the triangle in B represents the division of tasks, the boundary between design and installation responsibilities.

A triangle next to the pipe indicates that it needs to be laid at an angle.

It might be the boundary for material grade classification.

This legend doesn’t mention this specifically, so I wanted to ask
