Product introduction

Stainless steel tee for pipe fittings, pipe connectors. Used in the main pipe to branch pipe. The stainless steel tee has equal diameter and reducing diameter, and the nozzle end of the equal diameter tee is the same size; The main pipe size of the reducing tee is the same, and the nozzle size of the branch pipe is smaller than that of the main pipe.

Stainless steel tee is a pipe fitting for pipe branches. For the use of seamless pipe manufacturing tee, the process is usually used hydraulic expansion and hot forming two kinds. Hydraulic expansion of stainless steel tee is a forming process in which branch pipe is expanded by axial compensation of metal material. The process is to use a special hydraulic press to inject liquid into the tube blank with the same diameter as the tee. Through the two horizontal side cylinders of the hydraulic press, the tube blank is extruded synchronously. The volume of the tube blank becomes smaller after being extruded, and the liquid in the tube blank increases with the volume of the tube blank. The metal material flows along the inner cavity of the die under the double action of the liquid pressure in the side cylinder and the tube blank and expands the branch pipe.

The hydraulic expansion process of stainless steel tee can be formed at one time, and the production efficiency is high. The wall thickness of the head and shoulder of the stainless steel tee has increased.

Due to the large tonnage of equipment required for the hydraulic expansion process of stainless steel tee, it is mainly used for the manufacture of stainless steel tee with standard wall thickness less than DN400 in China. Its suitable forming materials are low carbon steel, low alloy steel, stainless steel, including some non-ferrous metal materials, such as copper, aluminum, titanium and so on.

According to manufacturing standards can be divided into national standard, electrical standard, water standard, American standard, German standard, Japanese standard, Russian standard, etc. Specific as follows: GB/T12459, GB/T13401, ASME B16.9, SH3408, SH3409, HG/T21635, DL/T 695, SY/T 0510, DIN 2615.

A stainless steel tee is a type of pipe fitting that plays a critical role in fluid handling systems. It is designed to connect three sections of piping, forming a T-shape that allows the flow of liquids, gases, or other materials to be split or combined efficiently. Made from high-quality stainless steel, these fittings are known for their exceptional resistance to corrosion, durability, and ability to withstand high pressures and extreme temperatures, making them indispensable in many industrial and commercial applications.

Types of Stainless Steel Tees

Stainless steel tees come in several types, each tailored for specific functions and installation requirements:

1. Equal Tee: An equal tee has all three branches of the same diameter. It is primarily used to combine or divide the flow of fluid evenly between different pipelines.

2. Reducing Tee: A reducing tee has one branch smaller than the other two. This type is essential when there is a need to reduce the pipe size while maintaining a smooth flow.

3. Threaded Tee: This version has internal threads on the branches, allowing it to be connected to threaded pipes without welding. It is often used in systems where quick assembly and disassembly are required.

4. Welded Tee: Welded tees are joined directly to pipes through welding, providing a permanent and leak-proof connection. They are widely used in high-pressure systems.

5. Socket Weld Tee: A socket weld tee is designed for small-diameter, high-pressure pipes, offering a strong and leak-proof joint through socket welding.

Materials and Standards

Stainless steel tees are typically made from a variety of stainless steel grades, including 304, 316, and 321, depending on the environment and application requirements.

• Grade 304: Known for its excellent corrosion resistance in most environments, making it suitable for water, steam, and mild chemicals.

• Grade 316: Offers superior resistance to saltwater and harsh chemicals, ideal for marine, chemical, and pharmaceutical applications.

• Grade 321: Contains titanium, providing better resistance to high temperatures, suitable for aerospace and power generation industries.

These fittings are manufactured according to international standards such as ASTM A403, ASME B16.9, and ISO 9001, ensuring high quality, reliability, and consistency.

Applications of Stainless Steel Tees

1. Chemical and Petrochemical Industry
Stainless steel tees are widely used in chemical plants and refineries where corrosive fluids and high temperatures are common. They enable the safe and efficient transport of acids, solvents, and other chemicals.

2. Water Treatment Systems
In municipal and industrial water treatment plants, stainless steel tees facilitate the distribution of water and chemicals, ensuring long-term reliability and preventing contamination due to corrosion.

3. Food and Beverage Industry
The food and beverage sector requires hygienic and non-reactive piping systems. Stainless steel tees help maintain sanitation standards while providing strong, leak-proof connections.

4. Oil and Gas Industry
These fittings are vital in oil pipelines and natural gas distribution systems, withstanding high pressures, fluctuating temperatures, and harsh environments.

5. HVAC and Plumbing Systems
In commercial and residential HVAC systems, stainless steel tees are used to distribute heating and cooling fluids, offering durability and longevity.
