Hydraulic Cylinders: Used in hydraulic cylinders for industrial machinery, construction equipment, and agricultural machinery.
Pneumatic Cylinders: Employed in pneumatic cylinders for automation systems, robotics, and manufacturing equipment.
Automotive Components: Utilized in automotive suspension systems, shock absorbers, and steering mechanisms.
Heavy Machinery: Suitable for various heavy machinery applications requiring reliable and durable cylinder components.
DIN2391 cylinder pipes offer customization options to meet specific customer requirements. These options include variations in dimensions, wall thickness, surface finish, and additional treatments such as honing, heat treatment, or surface coating, allowing for tailored solutions that match the unique needs of different cylinder applications.
Enhanced Strength: The cold drawing and rolling processes boost the yield and tensile strength of the pipes, making them ideal for high-pressure and demanding environments.
Increased Hardness: Improved surface hardness enhances wear resistance, ensuring longevity even under tough conditions.
High Fatigue Resistance: Our pipes are designed to withstand continuous cyclic loading, making them durable for long-term use
