Plate Flanges | EN 1092-1 Type 01 | DIN 2573

PM Industries manufactures, supplies, and stocks Plate Flanges in a range of materials, sizes, pressure ratings, and face configurations. A plate flange is cut or machined from flat plate stock rather than forged from a billet. The result is a flat circular flange body with a center bore and bolt holes around the perimeter. The face can be machined flat, raised, or left as cut depending on service requirements. No hub, no taper, no extended neck. What you get is a simple, functional flange at a lower material and manufacturing cost than a forged equivalent.

That cost difference is the primary reason plate flanges are specified. For low to moderate pressure service in non-critical applications, the mechanical performance difference between a plate-cut flange and a forged flange is acceptable. Plate flanges don't carry the same stress distribution benefits as forged weld neck flanges with their tapered hubs, and they're not suitable for high-pressure or cyclic-stress service where forged material is required by code. Within their applicable service range, they do the job reliably and economically.

Custom sizing is a practical advantage of plate flanges. Forged flanges are produced in standard nominal pipe sizes to ASME B16.5 and B16.47 dimensions. Plate flanges can be cut to non-standard bore sizes, non-standard bolt circles, and custom outer diameters that forged flanges don't cover. For equipment manufacturers building vessels, tanks, heat exchangers, and custom process equipment with non-standard nozzle dimensions, plate flanges provide a practical and economical way to produce flanged connections outside the standard range.

Water and utility service is a consistent application area. Large-diameter water piping, HVAC systems, and utility piping that operate at moderate pressures well below the ratings of the flange materials are natural fits for plate flanges. The pressure and temperature conditions don't require forged material with hub reinforcement, and the cost saving on high quantities of flanges in large-diameter utility piping is meaningful on a project budget.

Material flexibility follows from the plate cutting manufacturing approach. Any plate material that can be cut and machined can become a plate flange, including materials that aren't readily available as forgings. For projects requiring large-diameter flanges in duplex stainless, nickel alloys, or other specialty materials where forged billet availability is limited, plate cutting from available plate stock provides an alternative sourcing path.

Plate flanges are available with material certification to applicable ASTM plate and flange standards. Custom dimensions and non-standard bore or bolt circle configurations are available to order. Contact PM Industries for material selection, dimensions, face type, and pricing.
