Not so long ago, there was an open day at a factory that produces fittings and various parts. The employees shared their knowledge and interesting facts with the visitors of the exhibition. A small educational program helped many find answers to their questions. The most frequent request was to clarify what a tee for a pipeline is. The engineers explained that the tee is a connecting piece. It is used when installing pipes. The main function of such an element is to provide branching of streams. This happens by attaching a tee to the main branch. Steel tees GOST 173 76 01 are more often used for laying communications.
What are tees made of and what types of them are found?
Tees consist of two elements: the base of the product, from which three branch pipes extend. The part is produced by stamping from a solid sheet. This method pays off as it requires minimal production costs. In total, two types of steel tees can be distinguished: straight and flanged. The first option is used in cases when it is necessary to join pipes with similar cross-sectional parameters. The second option, on the contrary, is used to connect pipes with different cross-sectional parameters. Another criterion by which tees are divided is connection options. They can be welded or threaded. Flanged tee comes in the following varieties:
- flat welded;
- welded collar;
- free.
Each type of tee is regulated by a certain GOST, you can study them on the website
Tee categories
The tee is a versatile piece with which you can quickly connect to the main trunk line. That is why the device has the widest scope of application.
Tees have different characteristics and can be used in any industry. The main indicators are the section, the method of joining and the weight of the product. A wide range of various types allows you to significantly expand the scope of the part.
Some categories of tees are resistant to moisture, so the products are used when laying water pipes. Also stainless steel is more resistant to high and low temperatures. The working range varies from minus 70 to plus 450 degrees. That is why stainless steel products are most often used to ensure proper quality.
Seamless tees are used to install pipelines through which gas and oil are pumped. According to GOST, tees have different sizes. The weight of one product can vary from 190 grams to 131 kilograms.
Thanks to the plant workers, we learned that steel tees are an indispensable element that is most often used to branch off auxiliary pipes from the main line. Such devices must be as strong as possible, rust resistant, reliable and durable.
