Honed Tube Production Process
Raw Material Selection
High-quality seamless steel tubes are carefully selected as the base material to ensure strength, durability, and reliability.
Cold Drawing
The raw tubes undergo a cold drawing process to achieve the required dimensional accuracy and improved mechanical properties. This step ensures uniformity and precision.
Heat Treatment
After cold drawing, the tubes are heat treated in a furnace. This enhances toughness, hardness, and stress resistance, preparing the material for further machining.
Straightening
The tubes are straightened using an advanced straightening machine to eliminate bending or deformation. This ensures a stable foundation for honing or skiving.
Skiving and Roller Burnishing / Honing
Honing: The inner bore is processed with a honing machine to achieve the required surface roughness and precise tolerance.
Skiving & Roller Burnishing: Alternatively, tubes may undergo this process, which cuts the surface and simultaneously compresses it to create an extremely smooth finish and excellent dimensional accuracy.
Inner Surface Inspection
The inner diameter, roundness, and surface roughness are strictly checked to guarantee smooth bore quality suitable for hydraulic applications.
Final Quality Testing
Comprehensive tests are performed, including dimensional inspection, hardness test, roughness measurement, and hydraulic pressure tests if required by customers.
Cleaning and Protection
Tubes are thoroughly cleaned to remove dust, oil, or impurities, and coated with anti-rust oil to protect the inner bore and outer surface.
Packaging
Finally, honed tubes are packed in strong wooden cases or steel frames with end caps, ensuring safe transport and long-term storage.
