Phosphated Carbon Steel Honed Tubes are carbon steel tubing that undergoes an internal honing process and a surface phosphate treatment. They are specifically designed for use in core components of hydraulic and pneumatic systems. The honed interior achieves a high degree of finish and precision, enabling smooth fluid flow and movement in high-pressure environments. The phosphate coating on the surface enhances corrosion and wear resistance, further enhancing the overall performance of the material.
Internal Honing: Ensures smoothness and precision of the interior, reducing friction and improving sealing performance.
Phosphating: Forms a dense protective film on the surface, preventing rust while enhancing lubricity and durability.
High-Strength Carbon Steel: Provides excellent pressure-bearing capacity and mechanical properties, suitable for heavy-duty and high-pressure applications.
Standardized Dimensions: Conforms to international industrial pipe standards, facilitating compatibility with global equipment.
Honing is a key step in the production of phosphated carbon steel honed tubes. Through a high-precision grinding process, rough surfaces on the inner surface of the tube are removed, achieving micron-level precision. This process ensures tightness and sliding performance in hydraulic and pneumatic systems.
Phosphating treatment forms a thin phosphate film on the surface of carbon steel tubes. The specific steps include:
Surface Cleaning: Removes oil and oxides from the tube surface.
Phosphating Solution Immersion: A chemical reaction creates a dense phosphate coating on the tube surface.
Drying and Lubrication: After the coating is applied, drying and lubricant are applied to further enhance the tube’s corrosion resistance and lubricity.
In addition to phosphating, some tubes receive additional anti-rust coatings or spray treatments to meet the requirements of specific environments.
Phosphated Carbon Steel Honed Tubes are key components in hydraulic cylinders and hydraulic systems, used to manufacture cylinder barrels, piston rods, and other high-pressure components. Their high strength and corrosion resistance ensure long-term, stable operation of hydraulic systems.
In automated production lines and mechanical equipment, cylinders require high-precision barrels to ensure smooth gas flow and a tight seal. The smooth interior and durability of Phosphated Carbon Steel Honed Tubes fully meet these requirements.
In construction machinery such as excavators, loaders, and cranes, Phosphated Carbon Steel Honed Tubes are used to manufacture hydraulic cylinders and transmission systems, helping the equipment withstand high loads and harsh environments.
It is widely used in machine tools, molds, and other high-precision equipment for the manufacture of precision transmission and moving parts.
Used in hydraulic brake systems, suspension systems, and other critical components, they provide reliable performance and reduced weight.
Dimensions
Select the appropriate inner diameter, outer diameter, and wall thickness based on the design requirements of the hydraulic or pneumatic cylinder.
Working Pressure
Ensure that the selected tubing can withstand the system’s maximum operating pressure to avoid system failure due to insufficient strength.
Environmental Conditions
If the operating environment is humid or corrosive, tubing with a more complete phosphate treatment should be preferred.
Surface Quality
Inspect the tubing’s inner wall finish and the uniformity of the surface treatment to ensure it can meet the requirements of high-precision applications.
