ASME B16.11 Threaded Screwed Unequal Cross Manufacturer

What is Threaded Screwed Unequal Cross?

A Threaded Unequal Cross is a type of forged pipe fitting designed to connect four pipes at right angles while accommodating different pipe diameters. Unlike an equal cross where all outlets are the same size, an unequal cross features varying outlet dimensions, making it suitable for branching systems where flow reduction or distribution is required. It is commonly manufactured in accordance with ASME B16.11 standards and supplied in threaded (NPT/BSP) ends for easy installation without welding.

These fittings are widely used in high-pressure applications because the threaded connection provides a secure and leak-resistant joint. Threaded Unequal Cross fittings are typically made from materials such as stainless steel, carbon steel, alloy steel, duplex, and nickel alloys to ensure durability against corrosion, extreme temperatures, and mechanical stress. The design supports efficient directional changes and controlled flow distribution in complex piping layouts.

Industries such as oil & gas, chemical processing, water treatment, power generation, petrochemicals, and shipbuilding rely on threaded unequal cross fittings for safe and efficient fluid handling. Their ability to join different pipe sizes in cramped or restricted spaces makes them ideal for installations where welding may be impractical or restricted. With proper installation and material selection, these fittings deliver long-lasting performance and system integrity.
