Hydraulic Tube is the core pressure-bearing component in fluid power systems and is designed for safe delivery of high-pressure hydraulic oil. Its manufacturing process requires strict control of the product's mechanical properties (such as tensile and yield strength) to prevent tube explosions, while ensuring precise dimensional tolerances to achieve leak-free connections with various ferrules or flared joints. In addition, a smooth and clean inner wall is also essential to reduce flow resistance and protect the system's precision components.

TP304L stainless steel strikes an excellent balance between performance and cost for most fluid systems using conventional hydraulic fluids. It provides adequate corrosion resistance for non-aggressive fluid environments, while offering excellent cold bending and flaring properties to facilitate complex piping layouts during system assembly. Its excellent weldability and lower material cost make it a reliable and economical choice for most general industrial and mobile equipment hydraulic applications.

In hydraulic systems, cleanliness is critical. "Clean ID" means that the inner surface of the tubing is free of any drawing lubricants, metal shavings, or other contaminants. Once these tiny particles enter the hydraulic fluid, they can damage delicate components such as pumps, valves, and cylinders, leading to system failure and costly downtime. Our hydraulic tubing is specially treated and inspected to ensure a high level of inner wall cleanliness to effectively protect your equipment.

304L polished hydraulic tubing is the workhorse in many fluid systems. It is widely used in hydraulic systems of industrial machinery, engineering equipment and agricultural vehicles. It is also often used as fuel lines, lubricating oil lines and other fluid delivery lines in automobiles and ships. In these applications, it provides a solid guarantee for the smooth operation of the entire system with its reliable, clean and economical characteristics.

In order to ensure that our hydraulic pipes always maintain their high inner hole cleanliness and surface finish after leaving the factory until you use them on site, we use meticulous protective packaging. Each polished pipe is first individually wrapped in a plastic protective bag to isolate dust and moisture. Subsequently, both ends of the pipe are tightly sealed with plastic pipe caps to ensure that the inner hole is not contaminated during transportation and storage. Finally, the pipes are securely bundled and packed into sturdy plywood boxes.
