Butt-Weld Pipe Tee is a versatile T-shaped fitting designed for industrial piping systems, enabling seamless connections for branching pipelines at 90-degree angles. Conforming to ASTM A234 WPB standards, this carbon steel fitting offers superior pipeline corrosion protection and durability, making it ideal for boiler pipeline protection in oil and gas, petrochemical, and power generation applications. Its butt-weld design ensures leak-proof, high-strength joints for demanding environments.

Manufactured through seamless or welded processes, the Butt-Weld Pipe Tee is crafted from high-quality materials like ASTM A234 WPB (carbon steel) for general use or ASTM A234 WP22 (low-alloy steel) for high-temperature applications. 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 requirements. The fitting undergoes rigorous testing, including tensile, hydrostatic, and non-destructive tests (radiography or ultrasonic), to ensure compliance with ASME B16.9 and MSS SP-75 standards.

For pipeline corrosion protection, the Butt-Weld Pipe Tee can be coated with epoxy, galvanizing, or 3LPE, enhancing its resistance to harsh environments like offshore pipelines or chemical plants. Its robust construction withstands wear from abrasive materials and high-pressure conditions, making it a reliable choice 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, and facilitating easy installation in complex systems.

Unlike standard fittings, the Butt-Weld Pipe Tee can be adapted as a Piggable Tee (or Barred Tee) by adding internal bars for pipeline pigging, enhancing maintenance efficiency 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. This versatility makes it suitable for a wide range of applications, from oil and gas pipelines to power plant boiler systems.

The Butt-Weld Pipe 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 preferred choice for engineers seeking robust industrial piping and boiler pipeline protection solutions.

A butt weld pipe tee is a type of pipe fitting used to either combine or divide fluid flow in a piping system. The tee has a T-shaped configuration with two horizontal outlets and one vertical outlet, all connected via butt welds. This fitting is essential in many industries, including oil and gas, petrochemical, water treatment, and power generation, for directing, reducing, or splitting fluid flow.

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. Butt weld tee has a 90 degree branch along with a straight pipe, it will provide a connects for to install an additional equipment to a pipeline. With the tee structural, same sides of the ends could be welded to the pipe, 90 branch was left open for weld another pipe or a device.
