Note 1: All weights are approximate
Note 2: For Class 150, 300 the flange thickness “D" dimension includes
approx. 1.5mm for the raised face height. For Class 600, 900,
1500, 2500 the flange thickness does not include the raised face
height and approx. 6.4mm must be added to D dimension
Note 3: Bolt length dimensions incorporate the height of the raised face
Note 4: Welding Neck bore is derived from the pipe schedule

Note 1: All weights are approximate
Note 2: For Class 150, 300 the flange thickness “D" dimension includes approx. 1.5mm for the raised face height
For Class 600, 900, 1500, 2500 the flange thickness does not include the raised face height and approx. 6.4mm must be added
to D dimension
Note 3: Bolt length dimensions incorporate the height of the raised face
Note 4: Welding Neck bore is derived from the pipe schedule

Note 1: All weights are approximate
Note 2: For Class 150, 300 the flange thickness “D" dimension includes
approx. 1.5mm for the raised face height. For Class 600, 900,
1500, 2500 the flange thickness does not include the raised face
height and approx. 6.4mm must be added to D dimension
Note 3: Bolt length dimensions incorporate the height of the raised face
Note 4: Welding Neck bore is derived from the pipe schedule

Note 1: All weights are approximate
Note 2: For Class 150, 300 the flange thickness “D" dimension includes approx. 1.5mm for the raised face height
For Class 600, 900, 1500, 2500 the flange thickness does not include the raised face height and approx. 6.4mm must be added
to D dimension
Note 3: Bolt length dimensions incorporate the height of the raised face
Note 4: Welding Neck bore is derived from the pipe schedule
