Yes. VAMECA maintains an extensive inventory of flanges, particularly in metric DN/PN dimensions. Availability depends on the diameter, drilling pattern, material, and flange type. Please provide your part number or dimensions, and our team will verify the required configuration.
FLANGES & FITTINGS
Industrial and Metric Flanges
A part number, photo, or technical drawing is all we need to get started.
NPS / DN
CARBON STEEL & STAINLESS STEEL
Precision connection is all in the details.
Flange Drilling · Gasket Seating Surface · Material
Metric Inventory
DN / PN flanges engineered for your industrial requirements.
Product Identification Assistance
Markings, dimensions, and connection interfaces.
Flanges and Gaskets
A consistent, reliable choice across the entire assembly.
METRIC AT THE FOREFRONT
In-Stock Inventory for Your Metric Flanges
Connecting European-made valves, pumps, or industrial equipment? We maintain an extensive local inventory of flanges, with specialized availability in metric DN/PN dimensions.
Send us the required part designation or component dimensions. Our technical team will verify the configuration, local inventory levels, and lead times to meet your exact specifications.
Connecting European Equipment
Identify the standard and bolt pattern of the existing flange before selecting the mating companion flange.
Planning for Maintenance or a Turnaround
Consolidate part numbers, quantities, and required gaskets and seals to streamline procurement.
Complete an installation
Specify the piping and valve interface, along with operating conditions.
FLANGE TYPES
Selecting the Right Design
Weld neck, blind, threaded, or lap joint flanges: each design meets a specific piping assembly requirement. Materials, dimensions, and drilling patterns are confirmed based on the part number.
Schematic diagrams. The configurations shown illustrate our product lines and do not represent a guaranteed inventory of specific part numbers.
STANDARDS & END CONNECTIONS
DN / PN vs. NPS / Class: Distinguishing Between the Two Rating Systems
A similar nominal size does not guarantee compatible installation. Prior to ordering, ensure you verify the equipment's standard, bolt circle pattern, and flange sealing face.
Metric Flanges
DN / PN · EN 1092-1
DN and PN designations are used to specify metric flanges governed by the EN 1092-1 standard.
Looking for a legacy DIN reference? Please specify the standard indicated and include any available dimensions.
ASME Flanges
NPS / Class · ASME B16.5
Flanges governed by ASME B16.5 use NPS and Class designations, standard across North American facilities.
An "ANSI" request must specify the applicable standard, size, class, and flange facing.
PN16 and Class 150 are not direct equivalents. The outside diameter, bolt circle, bolt holes, and flange facing must all match.
PRODUCT IDENTIFICATION SUPPORT
A photo and the precise dimensions are all we need to proceed.
Nominal size alone is not enough to accurately identify a flange. Clear front and side-profile photos, along with the stamped markings, are required to initiate our verification process.
General arrangement drawing, not to scale (dimensions not indicated).
A
Outer Diameter
Measure the outside diameter (O.D.) of the flange.
B
Bolt circle diameter (BCD)
Measure the bolt circle diameter (BCD) across the center of the mounting holes.
C
Mounting Holes
Please specify the quantity and diameter.
D
Bore and Tube Connection
Measure the inside diameter. For a weld neck flange, also provide the pipe's outside diameter and wall thickness.
Please include a photo of the gasket seating surface, any markings, and your operating conditions. While dimensions guide identification, they do not replace formal technical validation.
THE RIGHT CONFIGURATION
Carbon Steel or Stainless Steel: Selecting Based on Operating Conditions
Selection applies to the complete assembly. Material and pressure ratings must be fully suited to the process media, temperature, and specific installation requirements.
Carbon steel, 304L stainless steel, or 316L stainless steel
Material selection depends on the media, its concentration, temperature, and operating environment. Specifying a stainless steel grade alone does not guarantee compatibility.
Pressure and Temperature
The PN rating or pressure class does not represent an allowable pressure across all temperatures. Applicable limits must be verified based on the selected material and design.
Flange Facing and Technical Documentation
Please specify flat face or raised face, the applicable standard, and any traceability requirements. If a 3.1 material test certificate is required, please indicate this at the time of your request.
COMPLETE ASSEMBLY
Also include the flange gasket
Gasket selection depends on the standard, facing type, media, pressure, and temperature. We can supply complete flange packages paired with standard or custom-cut sealing gaskets to meet your exact specifications.
Geometry and materials engineered specifically for your assembly's mating surfaces.
A product line to consider based on your flange configuration, bolt torque, and operating conditions.
Cross-reference the part numbers before having our experts validate the selection for your application.
Flange + Gasket + Fasteners
Flange facings, gaskets, bolting, and torque must be fully compatible. Component availability alone does not validate the integrity of an assembly.
