Import Asme 16.5 Orific Flanges — Buy in wholesale FOB from Supplier in India

ASME B16.5 orifice flanges from Renaissance Fittings And Piping Inc. are precision flow metering components manufactured to ASME B16.5 dimensional standards for differential pressure measurement in pipeline systems. These flanges accommodate orifice plates and are produced in sizes from 15 NB to 60 (1500 NB), with pressure classes spanning 150, 300, 600, 900, 1500, and 2500 LBS, plus PN6 through PN64 ratings. Material options include carbon steel (ASTM A105, A694, A350 LF2/LF3), stainless steel grades 304/304L, 316/316L, 321, 347 and duplex variants, plus nickel alloys, titanium, and copper alloys depending on service conditions.

The orifice flange assembly consists of a pair of flanges with jackscrews for orifice plate removal, plus pressure tapholes drilled in each flange for differential pressure measurement across the orifice plate. The orifice plate itself is a thin disc with a square-edged, concentric round bore that creates a known flow restriction. Standard conformance includes ASME B16.5, BS4504, EN1092, B1636, B1647, B1648, MSS SP44 and API specifications, with NACE MR 0175 certification available for sour service applications. Surface finish and dimensional tolerances are held to standard pipe flange tolerances to ensure gasket compatibility and bolt pattern alignment.

These flanges serve oil and gas transmission networks, petrochemical refineries, power generation plants, and water treatment facilities where accurate flow rate monitoring is critical. Buyers typically procure orifice flanges as complete sets including companion flanges, bolts, gaskets, and jackscrews. Renaissance Fittings And Piping Inc. supplies these components from their Mumbai location with mill test certificates per EN 10204 3.1. International buyers should confirm material grade certification, pressure testing documentation, and specific dimensional requirements for their orifice meter run design.

Renaissance Fittings And Piping Inc. operates from 67 Kika Street, Gulalwadi, Mumbai 400004, Maharashtra, India, serving as a manufacturer and exporter of industrial pipe fittings and flanges. The company lists ASME B16.5 orifice flanges across an extensive material range spanning carbon steel, stainless steel, duplex steel, super duplex, nickel alloys, titanium, and copper alloys, indicating substantial inventory breadth rather than narrow specialisation. The supplier's trust tier is classified as harbor with a 0.00 response rate and zero average response hours recorded, which suggests limited engagement data rather than verified transaction history.

The Mumbai location places Renaissance within India's primary metals and engineering cluster, with access to forging, machining, and heat treatment infrastructure. The listing emphasises dimensional accuracy, corrosion resistance, and finish quality without specifying proprietary processes or unique manufacturing capabilities. No verified export volumes, client references, or third-party audit certifications are stated in the source profile. Buyers should conduct direct due diligence on production capacity, inspection facilities, and prior orifice flange project references before committing to orders.
