Hello everybody:
In the book "Buried Steel Penstocks", 2nd Edition 1998 by Steel Plate Engineering Data - Volume 4, appears that the steel plate for penstocks is manufactured to two standards, ASTM A6 for structural use (ring girders, stiffener ring, lugs, etc.) and ASTM A20 for pressure vessels (pipe shells of large diameter).
I have made a search in the bibliography related to steel standards and it has been impossible, so far, ascertain what equivalences today match with those materials.
I will very much appreciate any input to this enquiry.
