Introduction to Hydraulic Tube
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.
Advantages of TP304L Material
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.
Importance of a Clean Inner Bore
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.
Application in Fluid Systems
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.
Professional Packaging Solutions
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.
