With an outer diameter of 6-1\/2 inches and a hub length of 1-1\/4 inches, this flange provides a secure, leak-resistant connection at the pipe terminus or joint. Rated at 175 psi and manufactured to Class 250 standards per ASME B16.1, it is built to handle demanding pressure service. Plumbers and pipefitters install this flange where threaded pipe must be bolted to a mating flange face on pumps, valves, or equipment.\u003c\/p\u003e\u003cp\u003eThis threaded pipe flange is suited for commercial and industrial plumbing, mechanical, and process piping applications where Class 250 cast iron fittings are specified. The eight-bolt hole pattern with 3\/4-inch bolt holes on 3-5\/16-inch centers provides balanced load distribution across the flange face. It is appropriate for systems requiring ASME B16.1 compliance, including water, steam, and general service lines in both new construction and retrofit scenarios.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eThreaded connection for 2-inch nominal pipe size\u003c\/li\u003e\n\u003cli\u003eClass 250 pressure rating per ASME B16.1\u003c\/li\u003e\n\u003cli\u003e175 psi working pressure\u003c\/li\u003e\n\u003cli\u003e8-bolt hole pattern with 3\/4-inch bolt holes on 3-5\/16-inch bolt hole centers\u003c\/li\u003e\n\u003cli\u003e6-1\/2-inch outer diameter with 1-1\/4-inch hub length\u003c\/li\u003e\n\u003cli\u003eCast iron construction for durability in commercial and industrial service\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-install component for 2-inch threaded pipe systems requiring Class 250 cast iron flanges conforming to ASME B16.1.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber or pipefitter in accordance with applicable mechanical and plumbing codes. Shut off and depressurize the system completely before removing any existing flange or making up threaded connections. Use appropriate pipe thread sealant or PTFE tape rated for the service medium before threading the flange onto the pipe. Torque all flange bolts evenly in a cross pattern to the specification required by the system design engineer.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 6-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHub Length\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBolt Hole Circle (Across Centers)\u003c\/strong\u003e: 3-5\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBolt Hole Diameter\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Bolt Holes\u003c\/strong\u003e: 8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 175 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass\u003c\/strong\u003e: 250\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASME B16.1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 5.15 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ANVIL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 0308500305\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASC ENGINEERED SOLUTIONS","offers":[{"title":"Default Title","offer_id":51544209654066,"sku":"0308500305","price":152.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/69c3602b3128dd7a901e35e4af01940d.jpg?v=1785925697","url":"https:\/\/voomisupply.com\/products\/anvil-0308500305-iron-threaded-pipe-flange-2in-class-250","provider":"Voomi Supply","version":"1.0","type":"link"}
