Dimensions: IGF flange, hub, and neck thicknesses meet or exceed ASME Sec. X, ASME RTP-1, ASTM D3299, and PS 15-69.
Pressure Rating: Flanges are stocked in 50psi, 100psi, and 150psi. All bolt holes and bolt circles are per ANSI B16.5 150 lb. drilling.
Not Machined: The nozzle necks and backs of IGF flanges are not machined. DuPont SW 12 S 6.7.1.1. says, “Overall machine facing of the back of the hand lay-up flange is not permitted.”

110 mil Corrosion Liner: C-Veil+Nexus+2 Mat.
Resin Coating: All bolt holes and spot facing are resin coated.
