The weight is approximate and calculated on base 7.85 Kg/dm3
Raw hole to be worked again according to the real external diameter of the pipe
For oil piping the flange should have 8 holes O.D. = outside diameter PCD = bolt circle diameter PN = nominal pressure in bars
Note: (1 bar = 14.5 psi = 0.1 MPa = 100 KPa = 1.02 Kgf/cm²)
