Butt weld tees are critical pipe fittings designed to create branch connections in piping systems, allowing fluid flow to be divided, combined, or redirected between the main pipeline and branch lines. They provide a reliable solution for pipeline expansion, process distribution, and complex piping layouts.
Available in equal tees and reducing tees, these fittings are manufactured from carbon steel, stainless steel, and alloy steel using advanced forming processes. With excellent mechanical strength, accurate dimensions, and reliable welding performance, butt weld tees are widely used in oil & gas pipelines, chemical plants, petrochemical facilities, power stations, and other industrial piping systems.

Features & Applications |
|
Carbon Steel Butt Weld Tees |
ASTM A234 WPB, A105, Q235 |
Provide high mechanical strength and excellent cost efficiency. They are widely used in oil & gas transportation, water supply systems, general industrial pipelines, and applications requiring reliable pressure performance. |
|
Stainless Steel Butt Weld Tees |
ASTM A403 WP304, WP316, WP316L |
Offer excellent corrosion resistance and durability. They are suitable for chemical processing, food and beverage production, pharmaceutical systems, marine engineering, and other corrosive environments. |
|
Alloy Steel Butt Weld Tees |
ASTM A234 WP5, WP9, WP11, WP22 |
Designed for high temperature and high pressure applications. They are commonly used in power generation, steam pipelines, petrochemical plants, and other demanding operating conditions. |
Our butt weld tees are manufactured according to international standards including ASME B16.9, ASTM A234, GB/T, DIN, JIS, and GOST.
Strict control of raw materials, forming processes, dimensions, and surface quality ensures reliable welding performance, accurate fit-up, and long-term service life in demanding piping systems.
Butt weld tees are widely used for pipeline branching and flow distribution in oil & gas transportation systems, petrochemical plants, chemical processing facilities, power generation projects, steam pipeline systems, water treatment facilities, shipbuilding and marine engineering, HVAC piping systems, pressure vessel piping and industrial process pipelines.
What is the difference between equal tee and reducing tee?
An equal tee has the same diameter for the main pipe and branch pipe, while a reducing tee has a smaller branch diameter for controlling flow distribution and connecting different pipe sizes.
What standards are your butt weld tees manufactured to?
Our tees are manufactured according to ASME B16.9, ASTM A234, GB/T, DIN, JIS, and other international standards.
What materials are available for pipe tees?
We supply carbon steel, stainless steel, and alloy steel tees, including ASTM A234 WPB, WP304, WP316L, WP11, and WP22 materials.
Can you manufacture non-standard tee fittings?
Yes. We can customize tee dimensions, materials, wall thickness, pressure ratings, standards, and markings according to customer project requirements.
