What size of bolts for flange 150 class 1" size?
What size of bolts for flange 150 class 1" size?
(OP)
I have to check what kind of bolts size should be on the flange 150 class and 1" size - (ANSI16.5) 150LB (PN20) 1"NB (DN25)?
On the web I have found many specifications but unfortunately they are different. Some of them shows bolts size 1/2" and some of them shows 5/8"... I'm confiused.
Thanks in advance for help

NPS 1"
OD of Flange: 4.25"
Dia. of Bolt Circle: 3.12"
Dia. of Bolt Hole: 0.62"
Number of Bolts: 4
Diameter of Bolts: 1/2"
Its somehow difficult inserting 5/8" (0.625") bolt into 0.62" hole……
