SELECTION SUMMARY · OVERVIEW
ASME B16.5 Alloy 20 Flange
ASME B16.5 Alloy 20 Flange is intended for bolted joints between piping, valves or equipment. Final suitability is subject to the project conditions, applicable standard and mutually confirmed order documents.
NOVUS selection noteConfirm flange type, standard and edition, NPS/DN, Class/PN, material, thickness/bore, facing, drilling, gasket, bolting and pressure-temperature rating.
Specify the material grade, nominal size, wall thickness or pressure class, connection and surface treatment.
Provide the quantity, packing, inspection and documentation requirements, destination and required delivery date.
NOVUS TECHNICAL DATA
Specifications, applications and product images
International standard designations, grades, dimensions and units are retained. Final supply parameters are governed by the NOVUS documents confirmed by both parties.
A flange is one part of a joint system comprising two compatible flanges, a gasket and bolting. Standard, dimensional series, pressure rating, material group, facing and bolt drilling must match; equal nominal diameter alone does not establish compatibility.
