what is the diffrence between orifices!

[hal1981]

Hi all!
does any one can explain difference between swaged orifice, restriction orifice and line sized orifice!

 

[europipe]

The first one is an orifice with a tapered hole in the plate,
Restr. orifice is the common name and maybe someone else knows what a line sized orif. is?

hal1981,

Where have found these terms?

I've heard "line size" orifice, rightly or wrongly, refer to an RO without reducers before or after.

I.e. a 10" line reducing to 8" or 6" for the orifice run and orifice flanges would not be a "line size" orifice.

For a more official definition, I suggest checking Nayyar's Piping Handbook.
