sorry for the off topic question here, anyone has a CAD detail showing connection between a reinforced concrete pipe and a ductile iron pipe that you can share? I have and existing RCP pipe that i am breaking at a big (14'x18') proposed concrete vault, and I want that pipe to continue through the vault as a ductile iron pipe, then pick up on the existing 30" RCP again on the other side. i do not think I can get RCP on 14' sections, but i believe i can get DI pipe, thus the hunt for a detail. any suggestions are highly appreciated
