DIN2391 Seamless Cylinder Hydraulic Customized Carbon Honing Piping
Main introduction
DIN2391 standard seamless hydraulic cylinder special carbon inner hole precision polishing pipe, is precisely designed for the hydraulic cylinder of high quality pipe. Using high-quality carbon steel as the base material and advanced internal hole polishing technology, these tubes ensure that the fluid resistance of the internal flow of the hydraulic system is minimized and the overall performance is improved.
 |  |  |
Core Features
Seamless construction: The highly durable seamless construction helps prevent leaks and enhances the long-term stability of the system.
Precision inner hole polishing: The precision inner hole polishing process provides a more uniform inner hole surface and reduces fluid friction.
Custom size: According to customer requirements, different outside diameter, wall thickness and length specifications can be customized.
Excellent corrosion resistance: The carbon steel material has been specially treated to increase the corrosion resistance.
Application
Inside the hydraulic cylinder: As the inner tube of the hydraulic cylinder, providing precise fluid control.
Delivery pipe: Used to transport hydraulic oil or other media used in hydraulic systems.
Automation equipment: Provides precise motion control in robotic arms and automated machinery.
Manufacturing standards
In line with DIN2391: strictly follow DIN2391 standards for manufacturing, to ensure the internationally recognized quality of products.
Cold drawing process: The application of cold drawing process to ensure that the steel pipe has high precision and good dimensional stability.
