Skived and Burnished Tube
Superior Precision: Hengtong Skived and Burnished Tube
The Ultimate Hydraulic Cylinder Tubing Solution That Sets Industry Standards
In the demanding world of hydraulic systems, the performance of core components directly determines the reliability, efficiency, and lifespan of the entire equipment. Hengtong Petroleum Machinery, leveraging its deep expertise in precision tube manufacturing, offers world-class precision-bored and rolled tubes—seamless tubes engineered for exceptional performance.
What is Precision Boring and Rolling?
Precision boring and rolling is an advanced, multi-faceted machining process. We first perform skiving to precisely mill the inner bore of high-quality seamless steel tubes, ensuring exceptional dimensional accuracy and straightness. Burnishing then cold-works the inner tube surface using high-pressure rolling tools. This process not only significantly improves surface roughness but also creates a dense, compressive stress layer on the inner tube surface, significantly enhancing fatigue strength, wear resistance, and corrosion resistance.
Our products are more than just components; They are the cornerstone of your equipment's reliability.
Unparalleled Surface Quality
- Mirror-Grade Finish: Internal surface roughness can reach Ra ≤ 0.4 μm or even lower. This exceptionally smooth surface significantly reduces friction, minimizing wear on seals and pistons, effectively preventing leaks and extending the life of the entire hydraulic system.
- Excellent Wear Resistance: The cold work hardening effect of the rolling process significantly increases surface hardness, resulting in wear resistance far exceeding that of ordinary honed pipes.
Superb Mechanical Properties
- Extreme Fatigue Strength: The compressive stress layer formed on the internal surface effectively inhibits crack initiation and propagation, enabling the pipe to withstand higher operating pressures and frequent pressure fluctuations. It is particularly suitable for high-pressure, heavy-load applications such as construction machinery and marine vessels. Excellent Straightness and Roundness: Our precise machining controls ensure the tubes have excellent straightness and roundness (±0.05mm tolerance), providing guidance for smooth piston movement, eliminating spooling, and ensuring precise and smooth equipment operation.
Perfect Combination Of Materials And Processes
- High-Quality Base Tube Selection: We strictly select high-quality ASME-certified alloy steel and seamless structural tubing as raw materials to ensure product mechanical properties and consistency from the source.
- One-Stop Manufacturing: Leveraging our complete industrial chain from cold drawing (Ø50-500mm), honing, to precision boring and rolling, we rigorously control every process to ensure impeccable overall quality of the finished tubes.
