Forged flanges

Precision forged. Machined for critical service.

DIMENSIONAL BASIS

ASME B16.5

Specify the pressure class your project requires. Seric confirms qualified combinations against each enquiry.

ASME B16.5 scope: NPS ½–24 for Classes 150, 300, 400, 600, 900 and 1500; Class 2500 extends only to NPS 12. These are standard designations, not a statement of Seric production capacity. ASME scope reference ↗

Planned portfolio range: ½″–24″. Send your required class, facing, bore and material. Each combination is subject to technical confirmation.
