A 1 1/2 Inch Equal Tee (NPS 1½, DN40) is a three-way pipe fitting designed to connect three pipes of identical diameter, allowing fluid to branch at a 90-degree angle while maintaining uniform pipe size across all outlets. This fitting plays a critical role in distributing flow evenly within industrial piping systems without altering velocity or pressure balance.
Manufactured in compliance with international standards such as ASME B16.9 (Buttweld Fittings), ASME B16.11 (Forged Fittings), and MSS SP-43, the 1 1/2 Inch Equal Tee ensures dimensional precision, structural strength, and long operational life. It is available in seamless, welded, and forged constructions depending on pressure class and service conditions.
Design & Construction
The equal tee features one straight run and one perpendicular branch, all measuring 1½ inches. This equal configuration ensures balanced fluid distribution and minimizes turbulence within the pipeline.
- Buttweld Equal Tee – Supplied with beveled ends for full-penetration welding in high-pressure systems.
- Socket Weld Tee – Ideal for compact high-pressure installations.
- Threaded Tee – Suitable for smaller bore and low-maintenance piping networks.
Precision machining ensures smooth internal bore surfaces to reduce friction loss and enhance flow efficiency.
