Socket Weld Crosses
What are Socket Weld Crosses?
A Socket Weld Cross is a forged pipe fitting used to create a four-way connection where one inlet divides into three outlets or vice versa. These fittings are engineered for high-pressure, small-bore systems, providing precise, leak-proof multi-directional flow in process pipelines.
Asiad Steel Industries is a leading manufacturer, supplier, and exporter of premium-quality Socket Weld Crosses in various sizes, grades, and finishes, providing robust and versatile piping solutions for a wide range of industrial applications globally.
