High-performance Pipe Tees For Corrosion Resistance In Petrochemical And Industrial Applications
A pipe tee is also called triplet,three way and 't' pieces and it can be used to either combine or split a fluid flow. tee is a kind of chemical pipe fitting with three ports, one inlet and two outlets; or two inlets and one outlet, t-shaped and y-shaped, with equal and reducer orifices, used in three identical or different pipeline convergence.
Permanent, high-strength welded connections.
For smaller diameter pipes, inserted and welded.
Easy assembly/disassembly, using threaded connections.
Bolted connections for easy removal and maintenance.
A pipe tee is a crucial pipe fitting used to either combine or split a fluid flow within a piping system. It is characterized by its T-shaped design, featuring three ports: one inlet and two outlets, or two inlets and one outlet.
Essential for creating branch connections for linear pipelines, allowing fluids to be redirected at specific angles, commonly 90 degrees.
Fabricated from various materials including stainless steel, carbon steel, and alloy steel, available in a wide range of sizes and finishes.
ASME/ANSI B16.9 pipe tees are critical fittings used to connect pipes and create branch connections in piping systems, ensuring robust corrosion resistance and reliability for boiler pipeline protection and erosion/corrosion resistance. Available in equal and reducing configurations, pipe tees are essential in industries such as petrochemical, power generation, chemical processing, and oil and gas.
Compliant with ASME/ANSI B16.9 standards, pipe tees are available in sizes up to 72″ (DN1800) and various wall thicknesses (e.g., SCH 40, SCH 80, up to 200 mm). They are manufactured from materials such as carbon steel (A234 WPB, P265GH), stainless steel (304, 316L, 1.4541, 1.4571), or alloy steel (A234 WP11, WP22). Surface treatments like pickling, passivation, or Fusion Bonded Epoxy (FBE) coatings enhance durability in corrosive environments.
Pipe tees undergo rigorous testing, including chemical analysis (e.g., A234 WPB: C ≤0.30%; 316L: C ≤0.03%), tensile testing (A234 WPB: YS ≥240 MPa, TS ≥415 MPa; 316L: YS ≥205 MPa, TS ≥515 MPa), hydrostatic testing (up to 9.8 MPa), and nondestructive methods (radiographic, ultrasonic, PMI). With a density of ~7.85 g/cm³ for carbon steel or ~8.0 g/cm³ for stainless steel, and suitability for temperatures up to 450°C (carbon steel) or 870°C (stainless steel), these tees excel in high-pressure piping applications like boilers, refineries, and chemical plants.
The butt-welded design ensures secure connections, making ASME/ANSI B16.9 pipe tees ideal for branching pipelines in harsh, corrosive settings, such as offshore platforms, power generation facilities, and petrochemical systems.

Industrial Applications
The pipe tee is currently the most frequently used pipe fitting or connector in the industry.
Its functionality is analogous to that of elbows, enabling the creation of branch connections for linear pipelines. As indicated by the name TEE, the shape is T-shaped with two outlets at 90° to the connection to the main line. The pipe piece is of a short length and features an integrated outlet. This is used to connect and take taps with a pipe at a right angle to the linear line. These can be fabricated with various materials, including stainless steel, carbon steel, cast iron, nickel, aluminum, copper, brass, bronze, plastic, rubber, and polypropylene. They are available in a variety of sizes and finishes, such as galvanized, nickel-plated, black cast steel, white coating, gold finish electroplated, and more. These options can be selected based on the end user's requirements. Pipe tees are a common solution in pipeline networks for transporting two-phase fluid mixtures. They can also be used as an alternative to o-rings.
The standard construction of T-shaped elbows (TEs) comprises three openings on the sides of the pipe tees, with two openings being narrower than the other. In some instances, the third opening may be at a 90-degree angle, subject to user requirements. In the case of straight pipe tees with identical opening sizes on all sides, these are referred to as equal tees. Alternatively, they may be classified as reducing tees, which feature one opening of a different size and two openings of the same size. Sanitary pipe tees are a type of pipe tee with a curved branch designed for a clean-out plug, and are used in waste lines. One advantage of this is that it prevents blockages in waste lines. Additionally, a cross pipe tee is available, featuring four equal-sized female openings. It should be noted that this type of pipe tee is not typically used in high-pressure systems and is not a common feature. The opening is threaded and used in conjunction with a threaded plug for a clean-out opening on a drain pipe. The ASME standards for tee design are ASME/ANSI B16.9 or ASME/ANSI B16.11, and the pipe tees are constructed by forging or casting.
