DIN2391 precision seamless steel tube are widely used in hydraulic and pneumatic systems in the fields of engineering and manufacturing. Precision seamless steel pipe are the backbone to ensure efficiency, safety and life. In this article, we will explore what makes DIN 2391 cold drawn precision seamless tube the first choice for hydraulic systems and why they are so important to your project.
What is DIN Precision Seamless Steel Tube?
DIN 2391 seamless precision steel tube is a high-quality material used in hydraulic and pneumatic systems. Seamless steel tube is manufactured to exacting tolerances and specifications. Unlike welded pipes, seamless tubing are seamless. The tubing is made from a single piece of steel, which provides high strength and durability.
These cold drawn tube are often used in industries that require high precision steel pipes, such as hydraulic systems, pneumatic systems, and automotive components. There are no welds, making them ideal for high-pressure environments.
Why Precision is Matters
High precision ensures that carbon steel tube meet the exact dimensions and tolerances required. In hydraulic and pneumatic systems, the inside diameters of various DIN cold drawn seamless tube must be precise to prevent leaks and ensure efficient fluid flow.
Accurate dimensions also improve the mechanical properties of the pipe. High precision pipes have excellent bending and torsional strength.

What is the Process of Precision Steel pipe?
Carbon steel pipe manufacturing process is cold drawing or cold rolling.
- Cold Drawing: It is the deformation of steel billet by stretching, which is usually used to produce precision steel tube. In this process, the billet is pulled through a die to reduce its diameter and wall thickness. So that the size of pipe can be controlled and the surface finish can be improved.
- Cold Rolling: The process of pressing strip steel into thin sheets or other shapes. For the production of steel pipes, cold rolling can be used for the processing of strip steel, and it can also indirectly affect the subsequent forming of the pipe. Compared with hot-rolled steel pipes, cold-rolled seamless precision steel pipes have material mechanical properties and gloss.
Both processes can improve the precision and consistency of carbon steel pipes, strictly complying with standards such as DIN 2391 and EN 10305-1.
What Is DIN 2391 Standard?
DIN 2391 tube is a German standard that specifies the requirements for steel grade precision seamless tubes used in mechanical and general engineering applications. It covers aspects like:
- Dimensions and tolerances
- Surface quality
- Mechanical properties
Adhering to the DIN 2391 standard ensures that the tubes are suitable for high-stress applications, offering reliability and safety.
Applications of Precision Steel Tubes
Hydraulic systems rely heavily on precision seamless steel tubes for efficient operation. These tubes are used to:
- Transport hydraulic fluids without leaks
- Maintain consistent pressure levels
- Withstand high operating pressures
The performance of these steel high precision tubes is critical, as any deviation can lead to system failures or inefficiencies.

How to Choose the Right Steel Grade for Your Needs
Selecting the appropriate steel grade is vital for meeting the specific demands of your application. Consider:
- Mechanical Properties: Assess the required strength, ductility, and toughness.
- Corrosion Resistance: For harsh environments, opt for tubes with higher corrosion resistance.
- Standards Compliance: Ensure the tubes meet standards like ASTM A519, EN1305-4, EN 10305-1, or DIN 2391.
Using tubes like carbon steel DIN 2391 or ST52 can enhance the performance and longevity of your systems.
Frequently Asked Questions
Q1: What is the difference between seamless and welded tubes?
A: Seamless steel tubes are manufactured without a seam, providing uniform strength, whereas welded tubes have a seam that can be a weak point.
Q2: Why use precision tubes in hydraulic systems?
A: Precision tubes ensure exact dimensions and superior surface quality, which are critical for the efficient operation of hydraulic systems
Q3: Are precision seamless pipes more expensive?
A: Yes, the expense of a precision seamless pipe of an identical specification tends to be higher than regular seamless pipes due to tighter tolerances and better surface finish.
