Alloy Tee

The size of alloy tees can be customized according to specific application requirements. Common sizes include but are not limited to 1/2 inch, 3/4 inch, 1 inch, 1-1/2 inch, etc. These dimensions refer to the diameter of the three-way connection, which depends on the pressure, flow rate, and required pipe size of the pipeline system. When choosing alloy tees, it is also necessary to consider their material and connection method to ensure that they can meet specific working conditions and performance requirements. ‌

Alloy tee is a type of pipe fitting made of alloy steel material. Alloy fittings include alloy tees, alloy tees, alloy reducers, etc., mainly used to connect pipelines and achieve the connection of pipes with different diameters. The production methods of alloy tees include casting, rolling, and stamping die methods. Casting method is to use a forging machine to punch and stretch the top or part of the pipeline, reducing the diameter to form a jointed bend pipe; The rolling method is applicable to the processing of the inner circular edge of thick walled pipes; The stamping die method is to use a smooth core in a punch press to increase the tube end to the specified specifications and shape.

The materials for alloy tees include various alloy steels, such as 12Cr1MoG, 15CrMoG, P91, etc. These alloy tees have the characteristics of acid and alkali resistance, with a smooth and flat surface, beautiful appearance, and strong texture performance. ‌

Alloy tees are mainly used to change the direction of fluids and are usually used where the main pipeline needs to branch. It can be used in water pipelines, oil pipelines, and various liquid chemical material transportation pipelines, and is widely used in fields such as medicine, water conservancy, energy, and construction. ‌

The materials of alloy tees include but are not limited to carbon steel, manganese steel, nickel steel, stainless steel, copper, aluminum alloy, plastic, argon slag, PVC, etc. The selection of these materials depends on specific usage scenarios and requirements.

For example, ordinary bronze alloy tees are more common in water pipes, but with the improvement of living standards, many water pipes have switched to stainless steel elbows. Manganese steel alloy tees are commonly used in pipelines with severe wear and tear, such as concrete and mud pipelines, due to their excellent performance in withstanding impact, compression, and material wear. The three general rules for alloys made of nickel steel are usually used in pipelines transporting high concentration oxidizing acids (such as nitric acid, sulfuric acid) at room temperature, but they will be severely corroded in pipelines transporting reducing acids (such as hydrochloric acid, dilute sulfuric acid, etc.) unless the concentration of hydrochloric acid is very low. Martensitic alloy tees have high high-temperature strength, oxidation resistance, and water vapor corrosion resistance below 650 ℃, but poor weldability, so they are often used in high-temperature water vapor transmission pipelines and water gas pipelines. ‌

In addition, the wear-resistant tee uses a special composite modifier to refine the grain size and is lined with high chromium nickel alloy, which has good wear resistance, temperature resistance, corrosion resistance and other characteristics. It is suitable for pipelines with high pressure, high concentration and long-distance transportation.

The size of alloy tees is mainly divided into two types: equal diameter tees and reduced diameter tees. ‌

The connecting ends of equal diameter tees are of the same size, meaning that the diameter of the main and branch pipes is the same. This type of three-way pipe fitting is more common in home decoration because its main and branch pipes have the same diameter, providing an equal diameter connection method. ‌

The three principles of reducing diameter have different size specifications, characterized by the same size of the main pipe connecting pipe, while the size of the branch pipe connecting pipe is smaller than that of the main pipe connecting pipe. This type of three-way pipe fitting is suitable for situations that require connections of different diameters, where the diameter of the branch pipe is usually smaller than that of the main pipe, providing a variable diameter connection method. ‌

Whether it is an equal diameter tee or a reducing tee, their size specifications can be obtained by consulting the relevant specification table for specific information. These specification sheets provide a detailed list of different sizes of tee fittings, including detailed parameters such as the diameter of the main and branch pipes, which facilitates engineers and designers in selecting suitable tee fittings. In addition, these specification sheets are also applicable to other types of three-way fittings, such as four-way fittings, which also follow the classification of equal diameter and reducing diameter, providing a range of standard sizes for selection.

The application scenarios of alloy tees are very wide, mainly used as a type of connecting pipe fitting in pipeline installation, for connecting at pipeline bends, making the pipeline make 90 ° or other angle turns. There are various materials for alloy tees, including carbon steel, manganese steel, nickel steel, etc. These materials play important roles in different application scenarios. ‌

(1) Alloy three made of carbon steel and manganese steel is commonly used in pipelines with severe wear and tear, such as concrete conveying pipelines, mud conveying pipelines, etc., because they have excellent performance in withstanding impact, compression, material wear, etc. ‌

(2) The three general rules for alloys made of nickel steel are particularly suitable for pipelines transporting high concentrations of oxidizing acids (such as nitric acid and sulfuric acid) at room temperature. Although they may corrode in pipelines transporting reducing acids (such as hydrochloric acid and dilute sulfuric acid), they can still maintain a certain level of durability in the presence of low concentrations of hydrochloric acid. ‌

(3) Martensitic alloy tees have high high-temperature strength, oxidation resistance, and water vapor corrosion resistance below 650 ℃, and are therefore commonly used in high-temperature water vapor transmission pipelines, water gas pipelines, etc. ‌

(4) GH4033 tee is a special alloy material that is widely used in petrochemical, aerospace, energy, and other industries such as marine engineering, metallurgy, food processing, etc. due to its excellent corrosion resistance, high temperature strength, and oxidation resistance. For example, in the petrochemical industry, GH4033 tees can be used in components such as storage tanks, reactors, pipelines, heat exchangers, etc., effectively extending the service life of equipment; In the aerospace industry, it can be used in components such as engines, turbines, high-temperature and high-pressure hydraulic systems to improve equipment performance and reliability; In the energy industry, GH4033 tees can be used to manufacture equipment such as nuclear reactors, gas turbines, coal-fired power generation units, etc., to improve equipment performance and reliability. ‌

In summary, alloy tees play an important role in various industrial fields due to their diverse materials and excellent performance, ensuring the safety and efficiency of fluid transportation.
