Types of Honed Tube
The honed tube produced by our company mainly include the following types:
ASTM A519 1026 Hydraulic Cylinder Tube
Hydraulic cylinder tube is finished inside diameter tube used in the manufacturing of hydraulic components. Hydraulic cylinder tube can be processed through skiving and roller burnishing or honing.
ASTM A519 1026 Honed Tube
Honed tube, also known as cylinder tube, is finished I.D. tube used in the manufacture of hydraulic components. Honed tube can be made from either cold drawn steel tube or hot rolled steel pipe through deep hole boring. Dingxin is able to manufacture 1026 unhoned tube, 1026 honed tube and SRB (skived & burnished) tube, which means Dingxin enable the quality at the very beginning of the production.
DIN 2391 ST45 ST52 Honed Cylinder Tube H7-H9
Honed tube, also called hydraulic cylinder tube, is used for hydraulic cylinder barrel. ST45 honed tube and ST52 honed tube are widely used as hydraulic cylinder tube due to their good weldability. ST52 is a low alloy steel that is not only hard but also have high tensile properties.
EN10305-1 E235 E355 Honed Tube
Honed steel tube or skived and roller burnished tubes are made of seamless cold finished precision steel tube. Compared to hot finished tubes, cold drawn seamless tube can provide continuous size range and optimized tolerances. The dimensions can be requested with inner diameter and wall thickness or inner diameter and outer diameter.
Honed Tube For Hydrulic Cylinder ST45 ST52 1026 E255 E355 20# 45# 25Mn Q345B 27SiMn
Honed tube for hydraulic cylinder, also called honed tube or SRB (skived and roller burnished) tube, is the most important part for manufacturing hydraulic cylinders.
Benefits of Honed Tube
Enhanced Performance in Hydraulic Systems
Honed tubes play a critical role in optimizing the performance of hydraulic systems. Their exceptionally smooth internal surfaces significantly reduce friction, thereby enhancing both the efficiency and service life of hydraulic cylinders. This minimization of friction leads to reduced wear and maintenance costs, ensuring continuous and reliable operation.
Superior Dimensional Accuracy
Honed tubing is distinguished by its exceptional dimensional accuracy. This level of precision is essential for applications requiring tight tolerances, as even minor deviations can compromise system performance or lead to failures. The honing process ensures uniformity across all tubes, enabling seamless integration into complex hydraulic systems.
Customization for Specific Applications
Manufacturers frequently provide customization options for honed tubes to align with specific project requirements. These options include adjustments to dimensions, surface finish, and material composition, tailored to meet the demands of various applications. Such customization ensures optimal tube performance in their intended environments, thereby enhancing the overall reliability of the system.
Longevity and Durability
The honing process not only refines the surface finish but also strengthens the structural integrity of the tube. This results in a product that is both dimensionally precise and highly durable. Honed tubes are capable of withstanding extreme pressures and temperatures, making them well-suited for demanding industrial environments.
Applications of Honed Tubes
Hydraulic and Pneumatic Systems
In hydraulic and pneumatic systems, honed tubes are crucial for cylinder applications. Their smooth internal surface ensures efficient fluid flow, reducing energy consumption and improving system response times.
Construction and Heavy Machinery
The construction industry relies heavily on honed tubes for equipment such as excavators, cranes, and bulldozers. These tubes ensure that hydraulic systems operate efficiently, enabling heavy machinery to perform demanding tasks with precision and reliability.
Automotive Industry
Honed tubes are also used in the automotive sector, particularly in shock absorbers and steering systems. Their dimensional accuracy and durability contribute to vehicle safety and performance, providing a smoother driving experience.
When a honed tube exhibits concave deformation and folding, the critical service life of its components may be compromised. Furthermore, this issue can adversely affect the normal operation of the entire system, particularly the most crucial parts of the cylinder. What are the potential causes of such concave deformation? There are several possibilities: one is excessive reduction during the cold drawing process or overly rapid transitions in the steel hammer head; another is uneven wall thickness, where localized areas are excessively thin. Additionally, outdated honing equipment that no longer meets pipe processing requirements may also contribute to the problem.
Regarding the concave bending phenomenon in seamless honed tubes, specific corrective measures can be formulated based on the identified causes. For instance, it is necessary to reasonably allocate the reduction amount during the cold drawing process. Regular inspections of all aspects must also be conducted to prevent undesirable phenomena, such as damage from hammers or substandard pipe materials. Moreover, traditional honing equipment should be upgraded or replaced when necessary. After implementing these improvements, similar defects should be effectively mitigated.
