ASME B16.11 Equal & Reducing Tees Manufacturers
ASME B16.11 Tee: Dimensions | Specifications | Material Grade | About Forged Tee | All Product Types
Forged Tees are critical components in high-integrity piping systems, designed to distribute or combine fluid flow in three-directional pipelines. Produced through a precision hot-forging process, these fittings are machined to close tolerances and conform to ASME B16.11 and BS 3799 dimensional standards, ensuring compatibility with global piping systems. Available in Equal Tee (where all outlets are the same diameter) and Reducing Tee (where the branch outlet differs in size), they offer flexibility in complex pipeline layouts. These tees are typically manufactured in Socket Weld (SW) and Threaded (THD) end types, including NPT and BSP threads, ensuring ease of installation without the need for welding in some applications.
Each Forged Tee undergoes rigorous quality control, including ultrasonic testing, hydrostatic testing, and chemical & mechanical property verification, to guarantee durability under high-pressure and high-temperature conditions. They are suitable for use across Class 2000, 3000, 6000, and 9000 pressure ratings, depending on the application’s pressure handling requirements. Material grades include Carbon Steel ASTM A105 and A350 LF2 CL.1/CL.2 for low-temperature service, Stainless Steel ASTM A182 F304/L, F316/L, F321/H, F347/H, and 904L for corrosion resistance, and Alloy Steel grades F1, F5, F9, F11, F22, and F91 for high-temperature and creep strength performance. We also offer Duplex (F51, F60), Super Duplex (F53, F55), and High Nickel alloys such as Inconel, Monel, Hastelloy, Alloy 20, and Copper Nickel 90/10, 70/30 for marine and aggressive chemical applications.
Forged Tees are widely deployed in Oil & Gas refineries, onshore and offshore drilling platforms, petrochemical plants, power plants, and marine piping systems, where leak-proof connections, corrosion resistance, and structural strength are non-negotiable. With reliable dimensional accuracy and superior metallurgical properties, these fittings play a vital role in ensuring long-term pipeline performance and safety.

A forged tee is a crucial component in high-pressure piping systems, designed to either distribute the flow from one inlet into two outlets or to combine flow from two inlets into one outlet. Produced in accordance with ASME B16.11, BS 3799, and MSS-SP-83 standards, forged tees are made by heating and pressing solid metal blocks into shape, resulting in superior grain structure and mechanical strength.
There are two main types of forged tees:
Forged tees are typically offered in socket weld and threaded (NPT/BSP) configurations, supporting sizes from 1/8” to 4” and pressure ratings ranging from 2000# to 9000#, depending on the material and end connection. Common materials include Carbon Steel ASTM A105, Stainless Steel A182 F304/F316, Alloy Steel, and Duplex & Super Duplex Grades like F51, F53, and F55.
Their robust design makes them suitable for use in critical sectors such as oil & gas transmission lines, chemical processing plants, power generation units, and offshore drilling facilities, where safety and reliability are paramount.
Each product undergoes a stringent quality control process to ensure it adheres to the highest international standards.

Forged tees are available in two main types, catering to different application requirements:
Equal forged tees have three branches of the same size, making them ideal for splitting flow in pipes of the same diameter. They are used in various industries for straight pipe connections where the flow rate is uniform.
Reducing forged tees have one branch with a smaller diameter than the main pipe, allowing them to connect pipes of different sizes. This makes them ideal for applications requiring a step-down in flow, such as pressure regulation or fluid redirection.
ASME B16.11 Tees are exported to key markets around the world, with a strong presence in Europe, the USA, and Middle Eastern & Gulf countries. These regions demand high-quality fittings for industries such as oil and gas, petrochemical, and chemical processing.
Countries served include:
We ensure fast, reliable delivery with full documentation for these markets, guaranteeing timely service and high-quality products.
Selecting the right material for forged tees is crucial to ensure performance, durability, and compatibility with the intended application. Common materials for forged tees include:
Equal and reducing forged tees serve similar functions but are used in different scenarios depending on pipe size requirements.
Choosing between the two depends on the specific design and flow requirements of the piping system.
