Straight Tee (Equal Tee)
A Straight Tee, also known as an Equal Tee, is one of the most commonly used branch fittings in piping systems. It features three outlets with the same nominal diameter, allowing fluid to be distributed evenly from a main pipeline into two branch lines or combined from two branch lines into a single flow.
With its symmetrical design, reliable performance, and easy installation, the Equal Tee is widely used in industrial, municipal, energy, and building piping systems where equal-diameter branching is required.
Product Features
• Equal Diameter Design
All three outlets have the same nominal diameter, ensuring balanced flow distribution and maintaining consistent pipeline capacity throughout the system.
• Efficient Flow Diversion
Allows smooth splitting or combining of fluid, gas, steam, or other media without significantly affecting flow performance.
• Symmetrical Structure
The T-shaped configuration provides stable mechanical performance and simplifies pipeline layout and installation.
• Multiple Manufacturing Options
Available in seamless, welded, and forged constructions to meet various pressure, temperature, and application requirements.
• Wide Material Availability
Manufactured in carbon steel, stainless steel, alloy steel, and other materials suitable for diverse operating environments.
Types of Straight Tees
By Branch Angle
90 Degree Equal Tee
The branch outlet is positioned at a 90° angle to the run pipe.
Benefits:
• Most commonly used configuration
• Easy installation and maintenance
• Suitable for general industrial and municipal piping systems
• Ideal for fluid distribution and collection
45 Degree Equal Tee
The branch outlet is positioned at a 45° angle to the run pipe.
Benefits:
• Reduced flow turbulence
• Lower pressure loss
• Improved flow efficiency
• Suitable for high-flow and high-viscosity media applications
