Product Overview

Forged Threaded Equal Tee

The Forged Threaded Equal Tee is a three-outlet fitting used to split a single threaded pipe run into two branches, or to combine two branch flows into one main run, using screwed NPT or BSP connections throughout. All three outlets carry female pipe threads of equal size. The branch outlet is positioned at 90 degrees to the run axis, forming a T-shaped geometry that allows flow to be distributed or combined at a single point without welding.

Threaded tees are used extensively in instrument manifolds, sample systems, utility distribution headers and maintenance-accessible process lines where the fitting may need to be removed or replaced during the plant's service life. Cunimet Alloy International manufactures threaded equal tees through closed-die forging, ensuring a structurally sound body at the critical crotch where the branch outlet intersects the run bore. All three outlets are threaded on CNC equipment to ASME B1.20.1 (NPT) tolerances and gauge-inspected before dispatch.

Technical Dimensions

Threaded Equal Tee — ASME B16.11 Dimensions

For an equal tee, the Centre-to-Face run dimension “M” and the Centre-to-Face branch dimension “C” are identical. All three outlets carry equal female NPT threads per ASME B1.20.1. All dimensions in millimetres.

Applications

Where Threaded Equal Tees Are Used

01

Instrument Manifolds

Building multi-point instrument manifolds for pressure gauges, transmitters and flow meters where threaded tees allow instruments to be connected and disconnected for calibration, replacement or relocation without cutting pipe.

02

Sample Systems

Creating sample tapping points in process lines where a threaded tee provides a permanent, corrosion-resistant branch connection for sample valves, injection quills and condition monitoring instruments.

03

Utility Distribution

Splitting steam, compressed air, nitrogen and plant water supply lines into two branches at a single distribution point using threaded tees that can be broken for line isolation or equipment removal.

04

Chemical Dosing

Connecting chemical injection pumps to two separate process lines from a single discharge header, using Stainless Steel or Duplex Steel threaded tees in the dosing skid pipework for chemical resistance and accessibility.
