EN1092-1 FLANGE TAP DRILLING 3/4" NPT
Hello All. Hope you can help. Based on EN1092-1 DN50 PN10/16 Type B Raised Face. I wanted to drill through and tap 3/4" NPT at the centre of the flange. Should the central through hole 3/4" NPT tapped from the raised face or it should be on the flat opposite face? Thank you!- NAZ1234
