Orifice Flanges
Orifice Flanges are specialized flanges used with orifice differential-pressure measurement assemblies and include provisions for pressure-tap connections.
Technical Parameters
- Nominal size and pressure class
- Orifice bore and flange dimensions
- Pressure-tap arrangement
- Facing type
- Bolt circle and bolt-hole details
- Material and grade
- Applicable ASME B16.36 edition
- Testing, marking and inspection
Orifice-Flange Standard
ASME B16.36-2025 is the current ASME edition identified for Orifice Flanges. It covers pressure-temperature ratings, materials, dimensions, tolerances, testing and marking for flanges with orifice pressure-differential connections. Its scope includes welding-neck classes 300, 400, 600, 900, 1500 and 2500, plus slip-on and threaded Class 300 configurations. citeturn0search7turn0search4
Materials & Grades
BCUBE can evaluate Mild Steel, Carbon Steel, Alloy Steel and Stainless Steel flange requirements in grades applicable to the selected material and flange specification. Material selection must match the pressure, temperature, corrosion and project requirements.
Dimensions & Rating
Flange pages will organize technical information around nominal size, pressure class/PN rating, facing, bore, outside diameter, thickness, bolt circle, bolt-hole count/diameter and other product-specific dimensions. Numerical tables will be added after specification-by-specification verification.
Current, Previous & Project-Specified Editions
BCUBE's standards database will distinguish current editions from previous/historical editions. ASME B16.5, for example, has historical editions including 2020, 2017, 2013, 2009 and earlier versions. citeturn0search18 A project specifying an older edition should be evaluated against that requirement rather than silently substituted with the latest edition.
Manufacturing & Sourcing
BCUBE supports both manufacturing and sourcing. Requirements can be evaluated from flange type, size, class/PN, facing, bore, material, grade, standard, drawing and quantity.
Testing, Certification & Inspection
Applicable dimensional, visual, material and pressure-related testing will be described according to the governing specification. EN 10204:3.1 material certificates and Indian or international third-party inspection can be supported where required.
Applications
Oil & gas, EPC projects, chemical and petrochemical plants, power plants, water treatment, industrial equipment, fabrication, infrastructure and general industrial piping, subject to the selected flange specification and service requirements.
