BOTHWELL® TAIWAN THREADED HALF COUPLING FORGED STEEL
The Bothwell® Forged Steel Threaded Half Coupling is a high-pressure branch connection fitting designed to connect a small-bore threaded pipe to a large-bore main header. With female threading on one end and a plain end welded directly to the header, it provides a strong, leak-tight branch tap. Manufactured from durable ASTM A105 forged steel (with stainless and alloy grades available) and compliant with ASME B16.11, Bothwell® threaded half couplings are a trusted choice for oil & gas, petrochemical, power generation and industrial applications across UAE and GCC.
