Notes: Class 150Ib - Class 300 Ib: Dimension B corresponds to the pipe inside diameter.

Values quoted assume 40S/Standard wallthickness.

Weights are based on manufacturer's data and approximate. Flat face flanges may be provided at full thickness, C, or with raised face removed (the latter is non-standard).

Class 600 Ib - Class 2500 Ib:

Dimension B corresponds to the pipe inside diameter. Vales quoted assume 40S/Standard wall thickness.

Weights are based on manufacturer's data and are approximate.

• Ratings from 300 lb to 2500 lb

• Sizes from 1" Nominal Bore

• Orifice flanges are intended for use instead of standard pipe flanges

• When an orifice plate or flow nozzle must be installed.

• Sure tappings are machined into the orifice flange, making separate

• Orifice carriers or tappings in the pipe wall is unnecessary.
