Weld neck flanges are engineered for high-stress piping applications where structural integrity at the flange-to-pipe joint is critical. The long tapered hub distributes stress evenly and provides reinforcement against bending and pressure loads. This flange is a standard-wall fitting suited for industrial and commercial piping systems and is typically installed by licensed pipefitters and mechanical contractors working on process, HVAC, or utility piping.\u003c\/p\u003e\n\u003cp\u003eThis flange is designed for use in Class 300 piping systems requiring a raised face sealing surface. The raised face configuration is compatible with standard spiral wound or ring gaskets and is commonly used in carbon steel process lines, steam distribution systems, and high-pressure water systems. Standard wall thickness conforming to ASME B16.5 makes it suitable for a wide range of commercial and industrial applications where carbon steel flanges are specified.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e12-inch nominal size, Class 300 pressure rating per ASME B16.5\u003c\/li\u003e\n  \u003cli\u003eRaised face sealing surface for use with standard compressed gaskets\u003c\/li\u003e\n  \u003cli\u003eCarbon steel construction per ASTM A105 for strength in pressure service\u003c\/li\u003e\n  \u003cli\u003eWeld neck design with tapered hub for stress distribution and fatigue resistance\u003c\/li\u003e\n  \u003cli\u003eStandard wall conforming to ASME B16.5 dimensional requirements\u003c\/li\u003e\n  \u003cli\u003eImport sourcing noted; verify project specifications for domestic material requirements\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation weld neck flange for Class 300 carbon steel piping systems conforming to ASME B16.5 dimensional and pressure-temperature standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified pipefitter or mechanical contractor in accordance with applicable codes including ASME B31.1 or B31.3 as required by the system service. Depressurize, drain, and isolate the piping system completely before welding or bolting any flange connection. The weld joint between the flange bore and pipe must be made by a certified welder and inspected per project specifications before returning the system to service. Do not overtighten flange bolts unevenly; follow a cross-pattern torque sequence using fastener specifications called out in the engineering drawings.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Class\u003c\/strong\u003e: 300\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlange Type\u003c\/strong\u003e: Weld Neck\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFace Type\u003c\/strong\u003e: Raised Face\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Carbon Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Standard\u003c\/strong\u003e: ASTM A105\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDimensional Standard\u003c\/strong\u003e: ASME B16.5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWall\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOrigin\u003c\/strong\u003e: Import\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ALLIED FITTING\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 929325-13338\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ALLIED FITTING","offers":[{"title":"Default Title","offer_id":51268943577394,"sku":"929325-13338","price":917.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/alliedweldneck_90bfdde7-1a00-4839-b199-f2efda510d71.jpg?v=1780710561","url":"https:\/\/voomisupply.com\/products\/allied-fitting-929325-13338-weld-neck-flange-12-in-300-class","provider":"Voomi Supply","version":"1.0","type":"link"}
