Forged Cross as per ASME B16.11 – Supplied in Threaded and Socket Weld Types – Equal and Reducing Options – Manufactured using A105, F304/F316, F5/F22, Duplex, Super Duplex, Inconel 625, Monel 400, and Hastelloy C276 for critical applications.
Forged Cross are vital components in piping systems where four-way connections are required. These fittings enable fluid distribution in multiple directions and are designed to maintain high structural integrity under pressure. Manufactured through precision forging, forged crosses provide superior strength, dimensional accuracy, and impact resistance compared to their cast or welded counterparts. Their robust construction ensures a secure, leak-free connection, making them ideal for high-stress and high-temperature applications.
Available in equal and reducing configurations, forged crosses are produced in sizes typically ranging from 1/8” to 4”, conforming to ASME B16.11 and MSS SP-79/SP-83 standards. End connections are offered in Socket Weld and Threaded (NPT/BSP) types, allowing easy installation and integration into various piping layouts. These fittings are available in a wide range of materials, including Carbon Steel (ASTM A105, A350 LF2), Stainless Steel (ASTM A182 F304, F316, F321, F347), Alloy Steel (F5, F9, F11, F22, F91), Duplex & Super Duplex, and Nickel Alloys such as Inconel, Monel, and Hastelloy.
Forged Crosses are widely used in oil & gas, chemical processing, refineries, marine, power plants, and offshore industries where flow diversion or merging from multiple directions is required. These fittings play a critical role in complex piping systems by maintaining uniform flow and ensuring structural balance at junctions. Thanks to their enhanced mechanical properties and corrosion resistance, forged crosses offer long service life, minimize maintenance needs, and ensure safety in critical operations.
ASME B16.11 Forged Crosses – Available in Equal and Reducing Designs with Socket Weld and Threaded Ends – Sizes from 1/8” to 4”, Pressure Ratings: 2000, 3000, 6000, 9000 – Built for high-strength, leak-tight branch connections.
