Seamless Honed Steel Tubing Series From Baokun
Honed tube refers to a type of metal tube that has undergone precision machining to ensure its inner diameter (ID) is smooth, uniform, and accurately sized. The honing process involves using abrasive tools to polish and remove material from the interior surface of the tube.
Honed ID tubing is commonly used in hydraulic and pneumatic cylinders, where the smooth surface minimizes friction between components such as pistons and seals. It is also found in industries like automotive, aerospace, construction, and manufacturing for various high-precision and high-performance purposes.

Seamless honed steel tubes are built to withstand wear and tear over time. Their durability means they require less maintenance and replacement, ultimately saving costs in the long run.
Our seamless honed tubes are designed with coatings or treatments that enhance their resistance to corrosion. This makes them suitable for use in challenging environments where exposure to moisture and chemicals is common.
Because they are seamless, these tubes do not have weld seams, which can be weak points. This seamless construction results in greater strength and allows them to handle higher pressures and loads without risk of failure.
The honing process creates a very smooth inner surface, which minimizes friction. This is crucial for efficient fluid flow, helping to improve the overall performance of hydraulic systems.

Manufacturing Process Processing
The production begins with selecting high-quality cold-drawn seamless steel tubes. These tubes are initially machined to achieve the desired dimensions, preparing them for further refinement. Surface irregularities are removed through processes like boring and skiving, setting the stage for the honing process.
The Honing Process
Honing is the defining step in the creation of honed tubes. Using abrasive tools, this process smooths and polishes the interior surface of the tube, ensuring it meets precise dimensional tolerances and surface finish standards. This improves the tube’s functionality, reducing friction and enabling efficient fluid or gas movement.
Quality Control and Testing
Quality control is paramount in honed tube manufacturing. Manufacturers implement rigorous tests to ensure dimensional accuracy, surface finish, and material strength. Pressure testing is also conducted to verify the tube’s ability to withstand high-pressure environments. These quality measures ensure honed tubes perform reliably in demanding industrial environments.

Frequent Asked Questions (FAQs)
1.What is a honed tube?
Honed tubes are precision-engineered metal tubes widely used in mechanical applications, known for their high accuracy and smooth internal surfaces. These tubes start as raw steel and undergo a honing process where an abrasive tool refines the inner surface to achieve a precise diameter and high-quality finish. This meticulous process makes honed tubes ideal for applications demanding exceptional accuracy and smoothness.
3. What is the process of honed tube manufacturing?
The honed tube manufacturing process begins with cold-drawn or extruded tubes, which have a rough inner surface. These tubes are first bored to remove excess material and bring the inner diameter closer to the desired size. Then, the honing process is carried out, where abrasive stones are used to grind the inner surface. This step smooths out imperfections and achieves precise dimensional tolerances. The honing ensures the tube has a smooth, even finish, reducing friction and wear. After honing, the tube is cleaned to remove any abrasive residue and then inspected for quality.
4. Can I order custom honed tubes?
Yes, honed tubes can be customized in terms of length, diameter, wall thickness, and material to suit particular applications. Baokun provides customization based on client specifications.
5. Are honed tubes resistant to corrosion?
Honed tubes are often made from corrosion-resistant materials or treated with protective coatings to enhance their durability, especially in environments exposed to moisture or chemicals.
