Is the ehd numer always on the piping? I noticed a piece of 3/4 had an ehd of 23. Is it safe to assume that all 3/4 has an ehd of 23 or that specific to that manufacturer

specific to manufacturer
one reason Mass was slow to accept PEX for water lines and CSST for gas is that sizes are not uniform from one manufacturer to the next and fittings are also not interchangeable.Cost is what you spend , value is what you get.
