Product details description
Custom bore orifice flanges provide precision flow measurement and control
solutions for industrial applications, enabling accurate process monitoring,
system optimization, and regulatory compliance in critical fluid handling
operations. These flanges conform to ASME B16.36 specifications for orifice
flanges, manufactured from materials including carbon steel, stainless steel
alloys (316L, 316Ti), duplex stainless steel (2205, 2507), and exotic alloys for
corrosive environments. The flanges utilize raised face designs with serrated
finish surfaces meeting ASME B16.5 roughness specifications, ensuring optimal
gasket sealing performance for high-pressure applications up to 2,500 PSI and
temperatures exceeding 800°F. Orifice plate specifications include various
materials from 304/316 stainless steel to exotic alloys, with thickness
tolerances of ±0.001 inches and hole diameter tolerances of ±0.0002 inches for
precise flow coefficient calculations. The bore configurations accommodate
multiple flow measurement standards including ASME MFC-3M, ISO 5167, and AGA
Report No. 3, with beta ratios ranging from 0.2 to 0.8 for optimal flow
measurement accuracy across various Reynolds number ranges. Pressure taps follow
ASME B16.36 requirements with minimum 1/4 inch NPT connections, utilizing corner
tap, D/2 tap, or flange tap configurations depending on application requirements
and pipe diameter specifications.
Professional orifice flange installations incorporate advanced measurement
and control features including integrated differential pressure transmitters
with 4-20 mA outputs, temperature compensation systems for accurate density
corrections, and smart transmitter configurations with HART protocol
communication for remote monitoring and diagnostics. The flange face designs
utilize RTJ (Ring Type Joint) configurations for high-pressure applications
exceeding 1,500 PSI, utilizing spiral wound gaskets with metal core materials
matching flange specifications for leak-tight performance under extreme
conditions. Flow measurement accuracy achieves ±0.5% of actual flow when
properly installed and calibrated, with repeatability specifications exceeding
±0.1% for critical process control applications. Installation procedures require
proper calibration techniques using traceable flow standards, correct flange
alignment with torque specifications meeting ASTM A193/194 requirements, and
periodic recalibration protocols to maintain measurement accuracy over extended
service periods. Quality assurance includes dimensional inspection per ASME
B16.5, pressure testing at 1.5 times design pressure, and metallurgical testing
to verify material specifications and heat treatment requirements. The custom
sizing process includes detailed flow analysis, pressure drop calculations, and
system integration requirements, ensuring optimal performance for specific
application conditions while meeting industry standards and regulatory
requirements.
