In the process of building a pipeline of various purposes, it is indispensable to use high-quality parts that are required in order to ensure the arrangement of a complex system configuration. Piping parts allow turning, lateral branching, changing the direction or diameter of the pipeline. Among the main types of such elements, the following are worth noting:
-
Bends;
-
Flanges;
-
Transitions;
-
Tees;
-
Stubs.

Steel flanges
The use of shaped elements is rational if it is necessary to create a system that is used to transport a wide variety of media. This is extremely often necessary in construction work, as well as in the construction of a domestic pipeline. We should also mention a connecting element called a steel flange, which is used most often due to its versatility.
Steel flanges are used to connect two separate pipe sections. Elements of this type are made in the form of a flat part with holes with a certain diameter, which corresponds to the current section of the pipeline. All technical characteristics of the product are governed by the established standards of GOST 12815-80 and look like this:
-
Maximum rated pressure - 200 bar;
-
The maximum temperature inside the pipe is +600 degrees.
Regarding the options for the material used in the production process, it is worth noting the division into the following types:
-
Gray cast iron. Produced in accordance with GOST 12817 and can withstand temperatures from -15 to +300 degrees. At the same time, the flow force should be no more than 160 bar.
-
Ductile iron. Produced in accordance with GOST 12818 and can be used under conditions of pressure up to 40 bar, as well as temperature conditions in the range from -30 to +400.
-
Steel 20. In the production process, the standards of GOST 8479 are observed, which ensures the possibility of operation at temperatures up to 475 degrees.
-
Stainless steel. Flanges made of this material are installed in systems where there is a risk of corrosive processes.
