DIN 2391 St35.8 is a standard specification for seamless precision steel tubes used in hydraulic and pneumatic systems. These tubes are often referred to as hydraulic tubes because they are specifically designed to meet the requirements of hydraulic systems, which demand precision, strength, and reliability.

 

Here are some key features of DIN 2391 St35.8 hydraulic tubes:

 

These tubes are manufactured using a seamless cold-drawn process, which ensures uniform wall thickness and excellent dimensional accuracy.

 

DIN 2391 St35.8 tubes have very tight tolerances on outer diameter and wall thickness. This precision is crucial for ensuring a proper fit in hydraulic systems.

 

These tubes are capable of withstanding high hydraulic pressures, making them suitable for a wide range of hydraulic applications.

 

The tubes have a smooth and clean surface finish, which is important for reducing friction and ensuring efficient fluid flow within hydraulic systems.

 

St35.8 refers to the material grade used in these tubes. It is a low carbon steel that offers good mechanical properties and is often used for hydraulic applications.

 

These tubes are typically delivered in a normalized condition, which improves their mechanical properties and ensures consistent performance.

 

DIN 2391 St35.8 hydraulic tubes are commonly used in various hydraulic and pneumatic systems, including in construction equipment, agricultural machinery, automotive components, and industrial machinery. These tubes play a critical role in the reliable and efficient operation of hydraulic systems, where fluid power is used to transmit force and control mechanical movements.

 

Its important to note that DIN standards are widely recognized and used in the European Union and other parts of the world. If you plan to use these tubes or need more specific information, its advisable to consult the latest version of the DIN 2391 standard and work with a reputable supplier to ensure you get the right product for your application.
