* Advanced manufacturing equipment and facilities, including: cold drawing machine, cold rolling machine, honing machine, skiving & roller burnishing machine, straightening machine, polishing machine, heat treatment furnace, grinding machine, cutting machine, etc. Our professional engineers do regular scheduled maintenance on these machines to guarantee them work well.
* High quality raw material: our raw materials for honed cylinder tube are mainly from the famous China steel makers, such as TPCO, SHA STEEL, BAO STEEL, which are best and largest steel manufacturers in China.
* High precision: Our honed tubes are manufactured with high dimension precision, tolerance can be ISO H7, H8 or H9, H10, depends on the sizes and customers' request. Which ensures the precision of the hydraulic cylinders.
* Reliable Packing: All the honed pipe will be oiled by the anti-rust oil before delivery. And to protect the inner diameter
surface of the honed ID tubing, we will cap the tube ends with plastic end caps, or if customer request we can weld a steel cap to protect the inner diameter of the honed id tubing during loading and unloading. And then the honed pipes will be packed with seaworthy package such as wooden cases or plastic bags.
* Strictly quality control: Our factory has a QC team of more than 10 persons. Every honed cylinder tube will be inspected before shipment. The inspections are carried according to corresponding standards and customers' requests, main test which including: Chemical Analysis Test, Tensile Test, Dimension Inspection, Roughness Test, Chrome plated thickness test, straightness inspection, and other tests according to standards and cusotmer's requirements.
* Mature quality management system: our Total quality management system ensures all the working processes related to product quality are in good control.
The Cold Drawn Honed Tube SAE 1026 NBK represents a pinnacle in the domain of precision-engineered seamless steel tubes, specifically designed to cater to the demanding requirements of hydraulic cylinder applications. This tube is meticulously manufactured using the SAE 1026 grade of mild carbon steel, which is known for its moderate strength and ductility, making it an ideal choice for high precision fluid power systems.
Starting with the cold drawing process, the steel tube is drawn through a die to achieve precise dimensions and a smoother finish. This method enhances the mechanical properties of the steel, increasing its yield and tensile strength, while also ensuring a high surface quality. The honing process follows, which involves fine-grinding the inner surface of the tube to achieve a precise diameter and a superior surface finish. This step is crucial as it reduces the roughness of the tube's interior surface, thereby minimizing friction and wear on hydraulic seals.
The NBK designation refers to a normalization process known as "Normalizing and Bright Annealing". In this process, the tube is heated to a temperature just above its critical range and then allowed to cool in air. This heat treatment results in a fine-grained, uniform microstructure that provides enhanced ductility and toughness to the tube. Following normalization, the tube undergoes bright annealing, a heat treatment that further refines the tube's surface, enhancing its corrosion resistance and giving it a bright, clean appearance.
The seamless nature of the tube ensures that it has no welded seams, thereby providing a uniform strength around the entire circumference of the tube. This feature is particularly important in high-pressure applications, as it significantly reduces the risk of leaks or bursts under pressure. Seamless construction also contributes to the tube's ability to withstand dynamic loads and high-speed movement of fluid, which are common in hydraulic systems.
In terms of applications, the Cold Drawn Honed Tube SAE 1026 NBK is extensively used in the manufacture of hydraulic cylinders, which are essential components in a wide range of machinery, including agricultural, construction, and industrial equipment. The precision dimensions and smooth interior surface of the tube allow for efficient movement of the piston, minimizing turbulence and optimizing the hydraulic system's efficiency.
To sum up, the Cold Drawn Honed Tube SAE 1026 NBK is a high-quality product that combines advanced material science with state-of-the-art manufacturing processes. Its superior strength, excellent finish, and dimensional accuracy make it a key component in hydraulic systems, ensuring reliability and performance in various demanding applications. Whether in the development of new machinery or in the maintenance of existing equipment, this tube stands out as a top choice for engineers and manufacturers alike.
