Stainless Steel Tees are butt-weld pipe fittings designed to connect three sections of piping and distribute or combine fluid flow. Available in equal and reducing configurations, they are manufactured from stainless steel grades such as 304/304L and 316/316L, offering corrosion resistance, strength, and durability for demanding piping systems.
Manufactured in accordance with applicable standards such as ASME B16.9 and ASTM A403/A403M, stainless steel tees are available in various sizes, wall thicknesses, and dimensions to meet project requirements. They are widely used in chemical processing, oil and gas, petrochemical, food processing, and water treatment industries. Material grades and specifications can be customized according to operating conditions and project requirements.

What is a stainless steel tee?
A stainless steel tee is a pipe fitting used to connect three pipe sections, allowing fluid to branch off or combine within a piping system.
What types of stainless steel tees are available?
The main types are equal tees and reducing tees. Equal tees have the same diameter at all three ends, while reducing tees have a smaller branch diameter.
What materials are used for stainless steel tees?
Common materials include 304, 304L, 316, and 316L stainless steel. The appropriate grade depends on the operating environment and corrosion resistance requirements.
Which standards apply to stainless steel butt-weld tees?
Stainless steel butt-weld tees are generally manufactured in accordance with ASME B16.9 for dimensions, tolerances, ratings, testing, and marking, and ASTM A403/A403M for material requirements covering wrought austenitic stainless steel fittings. Other applicable standards may be specified depending on the material grade, design requirements, and project specifications.
What sizes are available for stainless steel tees?
Stainless steel tees are available in various nominal pipe sizes and wall thicknesses, depending on the applicable standard and manufacturer’s production range.
What industries use stainless steel tees?
Stainless steel tees are commonly used in oil and gas, chemical processing, petrochemical, food processing, and water treatment systems, subject to the material’s suitability for the application.
Can stainless steel tees be customized?
Yes. Material grades, dimensions, wall thicknesses, and other requirements can be specified according to project needs and the manufacturer’s capabilities.
