Equal Tee for Industrial Piping and Corrosion Protection

Equal Tee is a T-shaped pipe fitting designed for industrial piping systems, connecting three pipes of identical diameter to form a 90-degree branch. Compliant with ASTM A234 WPB standards, this carbon steel fitting provides exceptional pipeline corrosion protection and durability, making it ideal for boiler pipeline protection in oil and gas, petrochemical, and power generation industries. Its butt-weld design ensures leak-proof, high-strength connections for demanding applications as of August 31, 2025.

The Equal 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) 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 Equal 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 reducing tees or piggable tees, the Equal Tee is optimized for uniform pipe diameters, offering simplicity and strength 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 HVAC applications.

The Equal Tee addresses critical challenges like pipeline wear, corrosion, and connection reliability 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.

The equal tee (equivalent tee or straight tee) is utilised as the branch has the same distance across as the run pipe. Equal Tee are equipped for taking care of any high or low weight stream of fluid through it.

Equal Tee (or straight tee), means the branch diameter of this tee is same with the main pipe (Run pipe) diameter of this tee.

The equal tee are with the same channel and outlet sizes, however, customers can profit from us “decreasing” tees too that have maybe a couple closes with various in measurement, this is called an equal tee. Because of their dimensional contrast, these tee fittings help with the ability to control the volume when required. Our scope of Equal Tee and Equal Cross are impeccably built utilising most recent innovation and are generally utilised as a part of differing piping frameworks crosswise over commercial ventures. Faultlessly built to flawlessness utilising most recent machines and innovation, these pipe fittings are broadly utilised as a part of a large number of commercial ventures far and wide. Durable in quality, these pipe fittings are accessible at competitive prices.

FAQ

An ASME B16.9 equal tee is used to create uniform branching in piping systems, connecting pipes of the same diameter for balanced flow in oil, gas, and boiler pipeline protection systems, ensuring pipeline corrosion protection.

Equal tees provide balanced flow, minimal pressure drop, and excellent corrosion resistance with materials like A234 WPB or 316L stainless steel and FBE coatings, ideal for high-pressure piping and petrochemical applications.

To select an ASME B16.9 equal tee, consider flow requirements, material compatibility (e.g., A234 WPB for carbon steel, 316L for corrosive fluids), pressure (≥9.8 MPa), and temperature (up to 450°C for carbon steel, 870°C for stainless steel) for optimal pipeline corrosion protection.

An equal tee requires precise butt-weld ends, high-quality materials (e.g., A234 WPB, 304 stainless steel), and coatings like FBE for corrosion resistance. It must meet ASME B16.9 standards for dimensional accuracy and weld integrity in high-pressure piping.

An equal tee is designed per ASME B16.9, ASTM A234, or ASTM A403 standards, ensuring dimensional accuracy, structural integrity, and compatibility with industrial piping systems.

The primary purpose of an ASME B16.9 equal tee is to create uniform branching in pipelines, ensuring balanced flow distribution and pipeline corrosion protection in oil, gas, and boiler systems.
