ASME B16.9 Lateral Tee
ASME B16.9 Lateral Tee Manufacturer & Supplier
ASME B16.9 Lateral Tee is a factory-made butt weld pipe fitting manufactured in accordance with the ASME B16.9 standard. It is designed to create a branch connection at a 45-degree angle, allowing smooth flow diversion while minimizing turbulence and pressure loss. Lateral tees are commonly used in piping systems where efficient directional flow and optimized pipeline layouts are required.
The ASME B16.9 standard specifies the dimensions, tolerances, materials, manufacturing, marking, inspection, and testing requirements for wrought butt welding fittings. Our ASME B16.9 lateral tees are manufactured using premium-quality raw materials and advanced forming processes to ensure superior dimensional accuracy, excellent mechanical strength, corrosion resistance, and long service life.
Available in various sizes, schedules, and material grades, our ASME B16.9 lateral tees are widely used in oil & gas, petrochemical, chemical processing, power generation, offshore, marine, water treatment, pharmaceutical, pulp & paper, and other industrial piping systems.

Frequently Asked Questions
What is an ASME B16.9 Lateral Tee?
An ASME B16.9 lateral tee is a butt weld fitting that provides a 45-degree branch connection for efficient fluid flow in industrial piping systems.
What is the difference between a Tee and a Lateral Tee?
A standard tee has a 90° branch, while a lateral tee has a 45° branch, which helps reduce turbulence and pressure loss.
Which material grades are available?
We manufacture ASME B16.9 lateral tees in Carbon Steel, Stainless Steel, Alloy Steel, Low Temperature Carbon Steel, Duplex Stainless Steel, Super Duplex Stainless Steel, and Nickel Alloy materials.
What sizes are available?
Our ASME B16.9 lateral tees are available from 1/2" NB to 48" NB, with custom sizes available upon request.
Which industries use ASME B16.9 Lateral Tees?
They are widely used in oil & gas, petrochemical, chemical processing, refineries, offshore, marine, power generation, water treatment, pharmaceutical, and other industrial piping systems.
