Unions of this type provide a three-piece threaded connection that allows a pipeline section to be disconnected and reconnected without rotating the pipe itself. The socket weld end prep accepts pipe inserted into the socket before welding, creating a strong, leak-resistant joint suited for high-pressure piping systems. Licensed pipefitters and industrial plumbers install this fitting in process piping, steam lines, hydraulic systems, and other demanding applications where full-bore flow and mechanical strength are required.\u003c\/p\u003e\n\u003cp\u003eThis union is appropriate for high-pressure, high-temperature service in both commercial and industrial piping installations. Class 3000 socket weld fittings are commonly specified in process plants, refineries, power generation facilities, and mechanical rooms where carbon steel piping is used. The 1-1\/2 inch size suits branch and mainline connections in mid-size process and utility piping systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass 3000 pressure rating for high-pressure service applications\u003c\/li\u003e\n  \u003cli\u003eSocket weld end connection for a strong, welded pipe joint\u003c\/li\u003e\n  \u003cli\u003eForged steel construction provides superior strength and durability\u003c\/li\u003e\n  \u003cli\u003eThree-piece union design allows pipe disconnection without rotating the pipe\u003c\/li\u003e\n  \u003cli\u003e1-1\/2 inch nominal pipe size suits mid-range process and utility lines\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for Class 3000 socket weld piping systems using 1-1\/2 inch nominal carbon steel pipe.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation must be performed by a qualified pipefitter or welder in accordance with applicable codes including ASME B31.1 or B31.3 as required by the system design. Depressurize and isolate the pipeline section completely before beginning any fitting work. Socket weld joints require the pipe to be inserted into the socket with a small gap left before welding per ASME code requirements. The union nut should be tightened to the ground joint seat only after the weld is complete and inspected.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: Socket Weld\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Class\u003c\/strong\u003e: Class 3000\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Forged Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.33 pounds\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: MATCO-NORCA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: mn-fw3un07\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MATCO-NORCA","offers":[{"title":"Default Title","offer_id":51619988537650,"sku":"MN-FW3UN07","price":49.09,"currency_code":"USD","in_stock":true}],"url":"https:\/\/voomisupply.com\/products\/matco-norca-mn-fw3un07-forged-steel-sw-union-cl3000","provider":"Voomi Supply","version":"1.0","type":"link"}
