Built from forged steel meeting ASTM A105 and ASME SA105 material standards, this flange handles pressures up to 740 psi across a temperature range of -20 to 100 degrees F. The raised face seating surface and FNPT connection type make it compatible with standard threaded pipe assemblies. Nominal size is 6 inches. Installation is performed by licensed pipefitters and mechanical contractors following ASME B16.5 dimensional and pressure-temperature standards.\u003c\/p\u003e\u003cp\u003eThis flange is suited for use in industrial process piping, HVAC mechanical rooms, water and steam distribution systems, and commercial plumbing infrastructure where a Class 300 pressure rating is required. The threaded FNPT connection allows installation without welding, making it a practical choice for field service and retrofit work. The raised face design ensures a reliable seal with standard spiral wound or ring gaskets at the flange joint.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eClass 300 pressure rating with 740 psi maximum working pressure\u003c\/li\u003e\n\u003cli\u003eForged steel construction per ASTM A105 and ASME SA105\u003c\/li\u003e\n\u003cli\u003eFNPT threaded connection eliminates the need for field welding\u003c\/li\u003e\n\u003cli\u003eRaised face seating surface for positive gasket seal\u003c\/li\u003e\n\u003cli\u003eComplies with ASME B16.5 dimensional standards\u003c\/li\u003e\n\u003cli\u003eDomestic manufacture\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in Class 300 flanged piping assemblies with 6-inch nominal pipe size, conforming to ASME B16.5 pressure-temperature ratings and bolt pattern requirements.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed pipefitter or mechanical contractor in accordance with applicable codes including ASME B31.1 or B31.3 as required by the system. Depressurize and isolate the piping system completely before beginning flange assembly or disassembly. Verify gasket type, bolt grade, and torque sequence are appropriate for the Class 300 service conditions per applicable piping specifications. Thread engagement should be confirmed prior to final bolt-up to ensure proper alignment and seal integrity.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Class\u003c\/strong\u003e: Class 300\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Pressure\u003c\/strong\u003e: 740 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature Rating\u003c\/strong\u003e: -20 to 100 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: FNPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFace Type\u003c\/strong\u003e: Raised Face\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 12.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBolt Circle Diameter\u003c\/strong\u003e: 10.62 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Bolts\u003c\/strong\u003e: 12\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBolt Hole Diameter\u003c\/strong\u003e: 0.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHub Diameter\u003c\/strong\u003e: 8.12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Through Hub\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 1.38 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1.81 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCounter Bore\u003c\/strong\u003e: 6.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Forged Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Standard\u003c\/strong\u003e: ASTM A105 \/ ASME SA105\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndustry Standard\u003c\/strong\u003e: ASME B16.5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: Domestic\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MACOMB GROUP APPROVED\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 340-060-000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MACOMB GROUP","offers":[{"title":"Default Title","offer_id":68300904399154,"sku":"340-060-000","price":306.91,"currency_code":"USD","in_stock":true}],"url":"https:\/\/voomisupply.com\/products\/macomb-group-approved-340-060-000-threaded-flange-6-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
