What Are Unequal Tee Fittings?
Unequal tee fittings, also called reducing tees, are butt weld pipe fittings that connect a smaller branch pipe to a larger main pipe at a 90-degree angle. They allow fluid to flow through the main line while directing part of it into a smaller branch. These fittings are commonly used in oil and gas, chemical processing, power plants and other industrial piping systems.
Unequal tee sizes are usually written as 8″ × 8″ × 6″, which means the main run is 8 inches and the branch is 6 inches. These fittings are manufactured to applicable standards, such as ASME B16.9, which covers dimensions and tolerances. The required wall thickness, material grade and pressure capacity depend on the fitting specifications, piping design and operating conditions.
Unequal Tee Fittings
High-quality unequal tee fittings for industrial piping systems, designed to connect pipes of different diameters, for demanding oil and gas, petrochemical, chemical, power generation, marine and engineering applications in various materials, sizes and grades.
Unequal Tee Fittings Types We Supply
As an experienced unequal tee fittings manufacturer, we offer different types to meet piping requirements across industrial applications.
- Standard Unequal Tee: Connects a smaller branch pipe to a larger main pipe for general piping systems.
- Seamless Unequal Tee: Made without a welded seam, suitable for demanding pressure and temperature conditions.
- Welded Unequal Tee: Suitable for larger pipe sizes, with weld inspection as required by project specifications.
- Hot-Formed Unequal Tee: Produced using heat and forming processes to achieve the required shape, including for larger sizes and thicker walls.
- Cold-Formed Unequal Tee: Formed without heating the material, offering good dimensional control for suitable sizes and wall thicknesses.
- Heavy-Wall Unequal Tee: Available in wall thicknesses such as Schedule 80 and XXS for applications requiring thicker walls.
- Stainless Steel Unequal Tee: Available in ASTM A403 grades and WP-S, WP-W or WP-WX manufacturing types, depending on the required specification.
- Alloy and Low-Temperature Unequal Tee: Grades such as WP11, WP22, WP91 and WPL6 suit high-temperature or low-temperature service, depending on the material.
- Duplex and Super Duplex Unequal Tee: Used in applications that require high strength and resistance to corrosion, including offshore and seawater systems.
- Barred Unequal Tee: Includes bars across the branch to help prevent pipeline inspection pigs from entering the branch line.
- Custom Unequal Tee: Manufactured to specified run sizes, branch sizes, material grades and dimensions based on project requirements.
Why Choose Unequal Tee Fittings?
Unequal tee fittings connect a smaller branch line directly to a larger main pipeline. They are useful in industrial systems where the main line carries fluid to several pumps, vessels, heat exchangers or other equipment. By providing the required branch size in a single fitting, they simplify pipeline connections and reduce the need for additional components.
Compared with an equal tee combined with a reducer, an unequal tee can reduce the number of fittings, welds and installation space required. Its factory-made design also helps achieve a consistent fit during installation. Depending on the piping design, it can offer a practical alternative to fabricated branch connections.
Branch strength, pressure and flow requirements are important when selecting an unequal tee fitting. The correct material grade, wall thickness and dimensions help the fitting meet the demands of the piping system. The need for additional reinforcement depends on the design code and application. These fittings are widely used in oil and gas, chemical processing, power generation and other industries where pipelines need branch connections of different sizes.
