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.

What is a Forged Tee and how is it used in industrial piping systems?

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:

  • Equal Tee: All three ends are of equal diameter, ensuring uniform distribution of pressure and flow.
  • Reducing Tee: The branch outlet is of a smaller diameter than the main line, allowing for controlled reduction in flow or pressure.

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.

What Types of Forged Tees are Available?

Forged tees are available in two main types, catering to different application requirements:

  1. Equal Tees (Straight Tee):

    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.

  2. Reducing Tees:

    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.

How Do I Choose the Right Material for Forged Tees?

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:

  • Carbon Steel (A105/A105N): Ideal for general-purpose applications in systems that handle lower-pressure and temperature conditions.
  • Stainless Steel (A182 F304/L, F316/L, F321/H): Provides excellent resistance to corrosion and is ideal for high-pressure and high-temperature applications in industries such as food processing, pharmaceuticals, and chemical manufacturing.
  • Alloy Steel (F11, F22, F91): Used in demanding high-temperature and high-pressure environments, particularly in the power generation and petrochemical industries.
  • Duplex & Super Duplex Stainless Steel: Known for excellent corrosion resistance in harsh environments, including marine and offshore applications.
  • Nickel Alloys: Offers high resistance to corrosion, making them suitable for chemical processing industries.
What Is the Difference Between Equal and Reducing Forged Tees?

Equal and reducing forged tees serve similar functions but are used in different scenarios depending on pipe size requirements.

  • Equal Forged Tees: These tees have three equal-sized openings, allowing the flow of the same diameter pipes in all directions. They are used in situations where the pipes connecting at the tee are of equal size, commonly found in industrial and commercial systems.
  • Reducing Forged Tees: These tees feature a smaller opening on one of the branches, allowing connection between pipes of different sizes. Reducing tees are used when a smaller pipe needs to be connected to a larger pipe, ideal for pressure and flow control in complex piping systems.

Choosing between the two depends on the specific design and flow requirements of the piping system.
