The DIN standard, very present every day in industries, is used to standardize the process of fixing parafuses, porcas and wheels. It is also used in other materials for manufacturing equipment and products. There are many examples of products manufactured according to the DIN standard: hardware, automobiles, heavy machines, jumpers, caps and many others.
Synonymous with security and international registration, the DIN standard has its origin on the other side of the Atlantic: in Germany, in the year 1918. Comparatively, we can say that the DIN standard is equivalent to the Brazilian ABNT standards. These, when they do not have a specific standard, adopt the DIN standard as a model!

Or what is the DIN standard?
DIN is an abbreviation of "Deutsches Institut für Normung", German Institute for Standardization. German organization for non-profit purposes, it represents the International Organization for Registration (ISO) in Brazil.
The institute provides registration services for more than a year. The DIN foundation began as a German Industrial Standards Committee (NADI), in December 1917. It was preceded by the Board of Directors Committee for German Mechanical Engineering, and in the same year of its foundation it had the first job of unification of conical pines. At the same time, standards for internal diameters, wedges and technical designs will also begin to be developed.
As two years have passed, the DIN standard has become a world reference in registration and security. The elaboration of the standards has more than 32.000 professionals of industry, research and government. Thus, it is possible to jointly promote the development of standards, as well as their dissemination, to ensure quality and safety for societies and markets.
What are the benefits of the DIN standard?
As well as other international standards, the use of the DIN standard plays a fundamental role in the industrial sector: standardization.
The technical standards of the DIN standard guarantee a high standard of quality in the manufacturing of products and equipment, providing safety throughout the process and directly impacting the safety of the final consumer.
Another benefit of the DIN standard is the reduction of automobile recalls, as well as problems with food products, household accidents, among others. Also, the DIN standard is also essential for:
Improved economy, reduced and increasing variety of products and procedures, reducing waste;
It facilitates better communication and relationships between everyone involved, offering more trustworthy and efficient exchange of information between the manufacturer and the customer;
Eliminates technical and commercial barriers and facilitates commercial exchange.
5 DIN standards for steel pipes
DIN 2440
DIN 2440 is similar to the Brazilian standard NBR 5580. DIN 2440 tubes are recommended for common uses in the conduction of non-corrosive fluids.
These tubes are supplied in classes L (Light), M (Medium) and P (Heavy), with no high frequency longitudinal welding, and also with no zinc coating.
All carbon steel tubes supplied in accordance with DIN 2440 must be subjected to the hydrostatic pressure test, at a pressure of 5 MPa for a minimum time of 5 seconds.
DIN 2391
The applications of two DIN 2391 steel tubes are determined by their characteristics of high dimensional precision existing in the external and internal diameters. Its surface is smooth due to the drawing process that is submeted. Only recommended for use in situations that demand precision, low thickness and specific surface conditions and mechanical properties.
DIN 2393
The DIN 2393 steel tubes are supplied in grades A (without special requirements or inspection certificates), B (with specific requirements and tests) and C (other types of steel, with mechanical properties or supply states not included in the previous grades) . They are also used in situations that demand precision, low thickness and specific conditions of surface and mechanical properties.
DIN 2394
The DIN 2394 steel tubes have exact dimensional dimensions. Laminates are made directly from a forming machine. Only seam tubes, supplied in circular section, with restricted dimensional tolerances. They are widely used in the auto parts industry, moving industry, bicycle industry, among others.
DIN 2458
The DIN 2458 steel tubes are supplied in circular section, rolled directly from a forming machine. There are no tubes with a seam, with the internal burr removed. They are only used in evaporators, heaters, gas conductors and super heaters. The DIN 2458 tubes are supplied in SAE 1008/1012.
It is very important that the consumer gives preference to companies rebuilt in the carbon tube distribution segment, which respect the standards for the most diverse applications.
At Tubonasa, a pioneering company in the segment, you can find steel tubes with DIN standards for your project. Access and confirm!
