Forged Cross Manufacturer, Supplier & Exporter
A forged cross is a four-way small-bore fitting with two run outlets and two opposite branches, all at 90°. Raaj Fittings manufactures and exports forged crosses with socket weld and threaded ends to ASME B16.11, from ¼" to 4" NPS, in stainless steel, duplex and super duplex, nickel alloys, carbon steel and alloy steel.
A cross brings four lines together at one point, or takes two branches from a line at the same place. In small-bore piping it is used to build compact manifolds, to provide a combined instrument and vent or drain connection, and in fire, air and water systems where a four-way junction saves space.
All crosses are supplied with EN 10204 3.1 mill test certificates, with 3.2 certification and third-party inspection on request.
We export forged crosses to EPC contractors, plant operators and stockists across the Middle East and GCC, Europe and the Americas — with NPT threads for US and Gulf projects or BSP threads where European and Middle Eastern specifications call for them.

Materials & Grades
We supply forged crosses in the following materials and grades. All grades are supplied with EN 10204 3.1 / 3.2 Mill Test Certificates.
Stainless Steel Forged Crosses
Stainless steel forged fittings deliver excellent corrosion resistance in chemical, pharmaceutical, food processing, and marine environments. All grades supplied to ASTM A182 specification.

Duplex & Super Duplex Stainless Steel Forged Crosses
Delivering approximately twice the yield strength of austenitic stainless steel with excellent resistance to stress corrosion cracking, pitting, and erosion — ideal for offshore, subsea, and chemical processing environments.
(UNS S31803 / S32205, ASTM A182 F51) Offshore topsides, chemical plant, and seawater cooling systems

Nickel Alloy Forged Crosses
For the most severe corrosive, high-temperature, and sour service environments where standard stainless steel grades are insufficient.
(UNS N06600) High-temperature oxidation and carburisation resistance
(UNS N06625) Outstanding corrosion resistance; offshore, chemical, and subsea service
(UNS N08825) Resistance to phosphoric and sulfuric acids; FGD and chemical plant

(UNS N08020) Engineered for sulfuric acid and aggressive chemical process service
Exceptional corrosion resistance in seawater and oxidising media at low density
Carbon Steel Forged Crosses
Carbon steel is the standard material for forged fittings in general-purpose, hydrocarbon, steam, and elevated-temperature service. The primary grade for forged carbon steel fittings is ASTM A105.
Primary grade for forged carbon steel fittings and flanges — covers ambient and elevated-temperature service in pressurised piping systems.
Low-temperature carbon steel, impact-tested for service down to -46°C (-50°F) — LNG, cold climate, and cryogenic piping applications.
Low-temperature carbon steel, impact-tested to -101°C (-150°F) — for the most demanding cold-temperature service applications.
Alloy Steel Forged Crosses
Chromium-molybdenum alloy steel grades for high-temperature, high-pressure service in power generation, petrochemical, and refinery applications. All grades supplied to ASTM A182 specification.
(5% Cr · ½% Mo) Refinery hydroprocessing and high-temperature service
(9% Cr · 1% Mo) High-temperature steam and hydrogen-rich process service
(1¼% Cr · ½% Mo) Thermal power plant steam, feedwater, and reheat piping
(2¼% Cr · 1% Mo) Reactors and high-temperature pressure piping in petrochemical plants
(9% Cr · 1% Mo · V · Nb) Ultra-supercritical power plant main steam and hot reheat piping
Where Forged Crosses Are Used
All four outlets of a forged cross have the same centre-to-end dimension as an forged equal tee of the same size and class, so a cross can be used wherever a tee would fit, with an extra opposed outlet.
- Small manifolds — distribution and collection points in instrument, hydraulic and utility systems.
- Combined connections — an instrument tapping with a vent or drain opposite.
- Fire and utility systems — compact four-way junctions on threaded piping.
- Cleaning access — a plugged outlet allows a line to be rodded or flushed.
Design Considerations
Because four flows meet at one point, a cross sees more turbulence and a higher stress concentration than a tee. Many process specifications therefore prefer two offset tees for critical hot or cyclic lines and use crosses mainly in utility, instrument and low-cyclic service. Unused outlets can be closed with a threaded forged plug.
Class and Pipe Schedule
As with all ASME B16.11 fittings, match the class to the pipe: socket weld 3000 with SCH 80, 6000 with SCH 160, 9000 with XXS; threaded 2000 with SCH 80, 3000 with SCH 160, 6000 with XXS. For a smaller branch, see the forged reducing tee; above 4" NPS, the buttweld cross is used.
Applications & Industries
- Instrument and hydraulic manifolds
- Fire water and sprinkler systems (threaded)
- Compressed air and inert gas distribution
- Chemical injection and dosing skids
- Process plant small-bore piping where space is limited
- Offshore utility piping in duplex and super duplex
When ordering, give the size, class, end type and thread form, and the material grade — for example 1" Class 3000 socket weld cross, ASTM A182 F316L. Crosses with mixed connections, such as socket weld run and threaded branches, can be made to order for manifold and instrument use.

Forged Crosses — FAQs
A forged cross is a four-way ASME B16.11 fitting with two run outlets and two opposite branches at 90°, with socket weld or threaded ends.
From ¼" to 4" NPS. Socket weld crosses in Class 3000, 6000 and 9000; threaded crosses in Class 2000, 3000 and 6000.
Yes. Each outlet of an ASME B16.11 cross has the same centre-to-end dimension as a tee of the same size and class.
In hot, high-pressure or cyclic process lines, where the higher stress at the four-way junction matters. Two offset tees are often preferred there.
Yes. Threaded outlets can be closed with a forged plug, and socket weld outlets with a short nipple and cap.
Carbon steel ASTM A105 and A350 LF2 / LF3, stainless steel ASTM A182 F304 to F347, alloy steel ASTM A182 F5 to F91, duplex and super duplex (F51, F53, F55) and nickel alloys such as Inconel 625 and Hastelloy C276.
