Rated for a 6,000 PSI Cold Working Pressure (CWP), this robust, large-bore hammer union provides a dependable, fast-makeup connection between welded 3-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, high-volume applications requiring maximum wall thickness to combat internal erosion, continuous vibration, and highly abrasive fluid transfer.\u003c\/p\u003e\n\u003cp data-path-to-node=\"5\"\u003eUnlike threaded unions, this large-bore Figure 602 assembly allows for a permanent, full-penetration welded integration into medium-pressure pipework. This securely eliminates the risk of thread-related leaks, galling, or loosening caused by the severe vibration and mechanical loads typical of truck-mounted pumping operations and massive 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 high-velocity abrasive slurry lines.\u003c\/p\u003e\n\u003cp data-path-to-node=\"6\"\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, high-flow conditions. The robust, heavy-duty wing nut design enables fast, tool-free assembly and dismantling of welded large-bore spools in the field, optimizing operational efficiency without sacrificing structural safety.\u003c\/p\u003e\n\u003cp data-path-to-node=\"7\"\u003e\u003cb data-path-to-node=\"7\" data-index-in-node=\"0\"\u003eFeatures \u0026amp;
