Socket Weld Unequal Cross
Socket Weld Unequal Cross
ASME B16.11 | Forged Socket Weld Reducing Cross | Class 3000–9000 | NPS 1 / 8–4
Elite Flow Co., Ltd. is a manufacturer, supplier, and stockist of high-quality Socket Weld Unequal Crosses, also known as Forged Socket Weld Reducing Crosses. These fittings are manufactured using controlled forging and precision-machining processes to provide dimensional accuracy, mechanical strength, and reliable performance in demanding piping applications.
A Socket Weld Unequal Cross is a four-way forged fitting in which the connection sizes are not all the same. It is designed to connect pipes of different diameters while maintaining a compact and robust piping configuration. The socket-weld ends allow the fitting to be welded directly into the piping system, providing a secure connection suitable for high-pressure applications.
ASME B16.11 Socket Weld Unequal Crosses are widely used in oil & gas, petrochemical, chemical processing, power generation, LNG, refineries, process plants, and general industrial piping systems. Elite Flow Co., Ltd. offers these fittings in carbon steel, stainless steel, duplex, super duplex, alloy steel, copper-nickel, nickel alloys, titanium, and other specialty materials.
