EN 10305-1 Seamless automotive steel pipes are high quality steel pipes manufactured in accordance with the European standard EN 10305-1 and designed specifically for the automotive industry. These tubes are prized for their precise dimensional tolerances, uniform wall thickness and superior mechanical properties, and are suitable for automotive drivetrains, braking systems and a variety of fluid transfer applications.
Hydraulic steel tubes with standard compliance are designed for high pressure and heavy load environments in hydraulic systems. They are commonly used in hydraulic cylinders, hydraulic tubing pipes and pneumatic systems to ensure the stability and safety of these systems during operation.
The DIN2391 standard, originated in Germany, outlines the exacting dimensions and stringent technical delivery terms for seamless precision steel tubes. Celebrated for remarkable precision and superior surface quality, these tubes undergo a meticulous cold drawing procedure that yields a uniformly smooth and refined exterior. Adhering to stringent tolerances with their well-defined measurements, DIN2391 specified hydraulic steel tubes guarantee an impeccable fit and superior functionality within hydraulic system applications.
EN10305 specifies the technical delivery conditions for seamless steel tubes for cold-drawn hydraulic and pneumatic systems, a Europe-wide standard. The EN10305 standard hydraulic steel pipe is similar to DIN2391 steel pipe in terms of accuracy and surface quality. The cold-drawn process ensures that they have a smooth surface. With precise tolerances, these tubes are ideal for applications that require high precision and reliable performance.
EN10216-5 is an additional standard within Europe that delineates the specific conditions for technical dispatch of seamless stainless steel pipes intended for pressure services. Although it doesn't concentrate on hydraulic systems exclusively, the EN10216-5 stainless steel pipes are suitable for use in hydraulic setups where there is a demand for materials with strong corrosion resistance and superior strength. The composition of these pipes from stainless steel imparts notably high durability against the elements and makes them fit for conditions that are quite rigorous.
Material characteristics:
Precision manufacturing: Seamless construction ensures maximum strength and reliability under extreme loads.
Corrosion resistance: Through special process treatment, surface corrosion resistance, adapt to various environmental conditions.
High strength: The steel pipe is made of high-grade carbon steel or alloy steel material, with excellent tensile strength.
Raw material selection: Start with refined steel materials to ensure the consistency of quality.
Perforation: Use the latest perforation process to ensure ductility and uniformity of the tube.
Cold rolling or hot rolling: the steel pipe is formed into a long tube shape without gaps, and then gradually cooled to maintain hardness.
Heat treatment: tempering or positive heat treatment to optimize the physical properties of the steel pipe.
Precision cold rolling: In order to achieve dimensional accuracy and surface quality, the steel pipe is further processed by cold rolling.
