A 3 Inch Equal Tee (NPS 3, DN80) is a high-performance pipe fitting designed to connect three pipes of equal diameter, allowing fluid flow to branch at a 90-degree angle without changing pipe size. This equal configuration ensures balanced flow distribution, stable pressure levels, and efficient system performance in medium to large industrial piping networks.
Manufactured according to international standards such as ASME B16.9 (Buttweld Fittings), ASME B16.11 (Forged Fittings), and MSS SP-43, the 3 Inch Equal Tee offers dimensional precision, high mechanical strength, and long service life. It is available in seamless and welded construction for buttweld applications, as well as forged versions for high-pressure systems.
Types Available:
- Buttweld Equal Tee – Designed for high-pressure and high-temperature applications, supplied with beveled ends for full-penetration welding.
- Socket Weld Tee – Suitable for high-pressure compact systems.
- Threaded Tee – Used in moderate-pressure installations requiring easier maintenance.
