Lateral Tee is a T-shaped pipe fitting designed for industrial piping systems, connecting three pipes with the branch extending at a 45-degree angle from the main run, optimizing flow diversion. Compliant with ASTM A234 WPB standards, this carbon steel fitting provides robust pipeline corrosion protection and durability, making it ideal for boiler pipeline protection in oil and gas, petrochemical, and power generation industries as of 11:51 PM PDT, August 31, 2025. Its butt-weld design ensures leak-proof, high-strength connections for demanding applications.

The Lateral Tee is manufactured using seamless or welded processes, utilizing high-quality materials like ASTM A234 WPB (carbon steel) for general-purpose applications or ASTM A234 WP22 (low-alloy steel) for high-temperature environments. Available in sizes from 1/2” to 48” (DN 15–DN 1200) for the main run, with equal or reducing branch sizes, and wall thicknesses such as SCH 40, SCH 80, or XXS, it meets diverse industrial piping needs. Rigorous testing, including tensile, hydrostatic, and non-destructive tests (radiography or ultrasonic), ensures compliance with ASME B16.9 and MSS SP-75 standards.

Engineered for pipeline corrosion protection, the Lateral Tee can be coated with epoxy, galvanizing, or 3LPE to withstand harsh environments, such as offshore pipelines or chemical processing plants. Its robust construction resists wear from abrasive materials and high-pressure conditions, ensuring reliability for boiler pipeline protection. The fitting supports welding methods (SMAW, GTAW, or GMAW) with low-carbon fillers, ensuring compatibility with pipelines like ASTM A106 Gr.B or API 5L Gr.B, facilitating seamless integration into complex systems.

Unlike Equal Tee or Reducing Tee fittings (90-degree branches, as discussed in your previous queries) or Piggable Tee fittings (with internal bars for pigging), the Lateral Tee offers a 45-degree branch for smoother flow transitions and reduced turbulence in industrial piping systems. For highly corrosive environments, stainless steel options like ASTM A403 TP347H provide superior corrosion resistance, while WPB offers a cost-effective solution for moderate conditions. Its versatility makes it suitable for oil and gas pipelines, petrochemical plants, power generation systems, and water treatment applications.

The Lateral Tee addresses critical challenges like pipeline wear, corrosion, and flow efficiency in high-throughput industrial systems. Its durable design and material options ensure long-term performance, safety, and efficiency, making it a top choice for engineers seeking robust industrial piping and boiler pipeline protection solutions.

A lateral tee is a specialized type of pipe fitting that features a T-shaped design, with an additional outlet at a 90-degree angle from the main pipeline. This unique configuration allows for the diversion of fluid flow from the main line to the lateral line, enabling efficient distribution to various destinations.

A lateral tee is a type of pipe fitting that is used to connect a branch line at right angles to a pipeline. It has a straight section of pipe, known as the "run," with a branch off of it at a 90-degree angle, called the "lateral." The lateral can be equal or unequal in size compared to the run.

Lateral tees are commonly used in piping systems where a new branch line needs to be added perpendicular to an existing pipeline. They are available in different materials such as carbon steel, stainless steel, alloy steel, and other metals, depending on the application.

There are two types of lateral tees: equal lateral tee and reducing lateral tee.

An equal lateral tee has branches of the same size, which means that the fluid flowing through the pipeline will be divided equally into the branch line.

A reducing lateral tee, on the other hand, has a smaller branch than the main pipeline. It is used when the flow rates in the branch line need to be reduced compared to the main pipeline.
