ASME B16.11 Half Couplings are precision-forged threaded pipe fittings manufactured to the ASME B16.11 standard, designed for connecting pipes or components in high-pressure, high-temperature piping systems. These half couplings provide a secure and durable threaded joint by allowing one end of a pipe to be reduced or connected to another threaded fitting or valve. Available in carbon steel, alloy steel, and stainless steel grades with NPT/BSP threading, ASME B16.11 half couplings are ideal for oil & gas, petrochemical, boiler, power, and general industrial applications where strength, reliability, and leak resistance are critical.
