Hy.
today I discovered an error on the database. As per Ansi B16-9 -2003 the radius of the LR elbows dn 3/4" have been changed to 38.1 ,as per DN 1/2" and 1".
also radius of 45° elbows have been changed.
Please updated your database since is stated the old radius.
see a screen shot of ansi B16.9-2003
