Rated for a 6,000 PSI Cold Working Pressure (CWP), this robust hammer union provides a dependable, fast-makeup connection between welded 2-inch piping systems. Featuring precision-machined Butt Weld ends designed to seamlessly integrate with Schedule XXH (Double Extra Heavy) pipe, this union is specifically built for heavy-duty applications requiring maximum wall thickness to combat internal erosion, continuous vibration, and abrasive fluid transfer.\u003c\/p\u003e\n\u003cp\u003eUnlike threaded unions, this Figure 602 assembly allows for a permanent, full-penetration welded integration into medium-pressure pipework. This eliminates the risk of thread-related leaks or loosening caused by the severe vibration and mechanical loads typical of truck-mounted pumping operations and heavy mud systems. The Double Extra Heavy (XXH) profile provides an extended operational lifespan by offering superior erosion allowance, making it an excellent choice for permanent cementing manifolds and abrasive slurry lines.\u003c\/p\u003e\n\u003cp\u003eManufactured from premium high-strength forged steel, the union features the hallmark Figure 602 replaceable lip-type elastomeric seal ring embedded securely into the female sub. This primary seal effectively protects the secondary metal-to-metal seating surface from abrasive fluids and corrosive agents, ensuring bubble-tight pressure containment under demanding conditions. The robust, heavy-duty wing nut design enables fast, tool-free assembly and dismantling of welded spools in the field, optimizing operational efficiency without sacrificing structural safety.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eFeatures \u0026amp; Benefits\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003e6,000 PSI Pressure Rating:\u003c\/b\u003e Engineered to safely manage continuous fluid transfer in medium-to-high pressure systems with a reliable 6,000 PSI Cold Working Pressure rating.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eButt Weld Connection (Sch XXH):\u003c\/b\u003e Precision-beveled ends designed for Schedule XXH (Double Extra Heavy) pipe provide maximum wall thickness, offering superior resistance to abrasive erosion and continuous vibration.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eReplaceable Lip-Type Seal:\u003c\/b\u003e Features a resilient elastomeric seal ring that provides a dependable primary barrier, minimizing turbulence and protecting metal seating surfaces from abrasive damage.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eDual Sealing Mechanism:\u003c\/b\u003e Combines the primary elastomer seal with a precision-machined secondary metal-to-metal seat for ultimate, leak-free pressure containment.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eForged Steel Construction:\u003c\/b\u003e Built from heavy-duty forged steel to deliver exceptional durability and resistance against mechanical impacts and rough field handling.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eRapid Spool Makeup:\u003c\/b\u003e The robust wing nut allows for quick, ultra-secure connections and disconnections between permanent welded pipe spools in the field.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cb\u003eSpecifications \u0026amp; Technical Details\u003c\/b\u003e\u003c\/p\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCategory\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003e\u003cb\u003eComponent Type\u003c\/b\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eHammer Union Assembly\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003e\u003cb\u003eUnion Figure Standard\u003c\/b\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eFigure 602 (Fig 602)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003e\u003cb\u003eNominal Size\u003c\/b\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e2\"\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003e\u003cb\u003eEnd Connection\u003c\/b\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eButt Weld (BW)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003e\u003cb\u003ePipe Schedule Compatibility\u003c\/b\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eSchedule XXH (Double Extra Heavy)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003e\u003cb\u003eMaximum Working Pressure\u003c\/b\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e6,000 PSI CWP\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003e\u003cb\u003eSealing Mechanism\u003c\/b\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eReplaceable Lip-Type Seal \u0026amp; Metal-to-Metal\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003e\u003cb\u003eBody Material\u003c\/b\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eHigh-Strength Forged Steel\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003e\u003cb\u003eTypical Applications\u003c\/b\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eMud manifolds, cementing lines, truck mounting, abrasive service\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e\u003cb\u003eApplications\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eThis heavy-duty 2\" Figure 602 Schedule XXH butt weld hammer union is essential for flowline networks requiring extreme structural rigidity, erosion resistance, and reliable leak-free containment.
