ASME B16.11 | Forged Socket Weld Half Coupling | Class 3000–9000 | NPS 1/8–4
Elite manufactures and supplies high-quality Forged Socket Weld Half Couplings for industrial piping, instrumentation, process, and fluid-handling applications. These fittings are manufactured from high-quality raw materials using controlled forging and precision-machining processes to provide reliable dimensional accuracy, strength, and consistent performance.
A Socket Weld Half Coupling is a forged fitting with one socket-weld connection and one outlet end, allowing it to be welded directly to a pipe, header, or other piping component. Stainless Steel Socket Weld Half Couplings are commonly used for branch connections, instrument hook-ups, small-bore piping, and process connections where a compact and reliable connection is required.
ASME B16.11 Forged Socket Weld Half Couplings are available in a wide range of sizes, pressure classes, and materials to meet different project requirements. Elite supplies carbon steel, stainless steel, alloy steel, duplex, super duplex, copper-nickel, nickel alloys, titanium, and specialty-material configurations.
