Tee – pipe fitting
The definition of pipe tee:
The pipe tee is a connection method in the pipeline, and its main function is to add or separate a branch pipe into the pipeline.
It is mainly divided into two kinds of straight tee and reducing tee. The straight tee means that the branch pipe diameter is the same as the female pipe diameter. And the reducing tee means that the branch pipe diameter is different from the female pipe diameter.

The application of tee pipe fittings:

1. Petrochemical industry: Tees are widely used in petrochemical, fertilizer and other industries, such as oil transmission, gas transmission, chemical process, discharge system, etc.
2. Food and pharmaceutical industry: Tees are also widely used in food and pharmaceutical industry, such as conveying food liquids, pharmaceutical raw materials, etc.
3. Construction industry: Tees are mainly used in thehe construction industry for water supply, drainage and heating.
4. Other industries: Tees are also widely used in other industries, such as shipbuilding, water conservancy, air conditioning, etc.
Introduction
Tee national standard range:
At present, the relevant international regulations for pipe tees mainly include ASME, JIS, GB, DIN and other standards. Among them, the national standard mainly stipulates the requirements of materials, models, sizes and other aspects of the pipe tees.
Material selection of tee pipe fittings:
There are many kinds of materials of pipe tees, commonly used carbon steel, stainless steel, alloy steel, copper and other materials. The specific material selection should be selected according to the working environment and process requirements.
Size standard for tee:
The size standard of the tee mainly involves the diameter and thickness of the pipes, the angle of the tees, etc. Specific size standards should be selected according to international, national and industry standards.

Conclusion
In short, the pipe tee is one of the common connection methods in the current pipeline. It is widely used in various industries and has an important role and significance.
When selecting tees, the selection should be made as the specific working environment and process requirements. And follow the requirements of international, national and industry standards.
