Common tees and reducing tees are commonly used pipe fittings in pipeline connections. The differences between them are mainly reflected in the following aspects.

1. Name and definition:

A tee fitting is a fitting that connects two pipes with a third pipe perpendicular to them to divert or collect fluids. Usually, it consists of one entrance and two exits.

Reducing tee fittings are also called reducing tee fittings. The difference from ordinary tee fittings is that the diameters of the two outlets of the reducing tee are not the same, but have different diameters.

2. Structure and use:

Common tee fittings have a simple structure and usually include an inlet and two outlets of the same diameter. It can connect two pipes and divert fluid to two directions. It is often used to distribute fluid or collect fluid. Tee pipe fittings are widely used in pipeline systems in petroleum, chemical industry, fertilizer, electric power, metallurgy, papermaking, light industry, medicine, food, health and other industries.

Compared with common tee fittings, variable diameter tee fittings have the characteristic that the pipe diameters of the two outlets are different. It can connect two pipes with different diameters, adjust the flow of the pipes according to actual needs, and realize the collection, divergence or confluence of fluids. Reducing tee fittings are widely used in pipeline systems in chemical, electric power, metallurgy, construction, shipbuilding and other industries.

3. Manufacturing process and materials:

Common tee fittings are generally made by forging, casting or welding processes. In terms of material selection, carbon steel, stainless steel, alloy steel, copper, aluminum, plastic and other materials can be used.

The manufacturing process of reducing tee fittings can also be forged, cast or welded. In terms of material selection, appropriate materials are usually selected based on actual needs and working environment, such as carbon steel, stainless steel, alloy steel, copper, aluminum, plastic, etc.

4. Interface form:

Common interface forms of tee pipe fittings include threaded connection, welded connection and flange connection.

The interface forms of reducing tee fittings are similar to ordinary tee fittings, including threaded connections, welded connections, flange connections, etc.

5. Scope of application:

Common tee fittings are suitable for connecting two pipes of the same diameter, and there is usually no need for diameter changes.

Reducing tee fittings are suitable for connecting two pipes with different diameters, and the diameter can be changed and adjusted according to actual needs.

6. Installation and maintenance:

The installation and maintenance of common tee fittings are relatively simple. It is necessary to ensure that the connection is tight and the sealing is reliable to prevent leakage.

The installation and maintenance of reducing tee fittings are also relatively simple, but it is necessary to pay attention to changes in pipe diameter and fluid adjustment requirements to ensure the normal operation of the fluid and the stability of the pipeline system.

To sum up, there are certain differences between common tee fittings and reducing tee fittings in terms of names, structures, uses, manufacturing processes, materials, interface forms, scope of application, installation and maintenance. According to actual needs and engineering requirements, selecting the appropriate type of pipe fittings can realize the connection, divergence or confluence of pipelines, ensuring the normal operation of the pipeline system and the transmission effect of the fluid.
