Are you still struggling with insufficient tube precision? Are you still frustrated by poor tube wear resistance?

      In fact, the root causes of the "precision anxiety" and "wear resistance pain points" of tubes often lie in the compatibility between material selection and processes. Ordinary tubes mostly adopt traditional hot-rolling processes. After forming, their dimensional tolerance is usually above ±0.1mm, and the surface roughness can only reach Ra1.6μm. This not only fails to meet the assembly requirements of high-precision equipment but also cannot withstand complex working conditions such as long-term friction and high-pressure impact. The real solution to these problems lies in high-quality tubes processed through refined cold working—such as the cold-drawn tubes and honed tubes that Jianlida Technology has focused on developing for 16 years.

      Take Jianlida's cold-drawn tubes as an example. Through the core processes of "multi-pass cold drawing + intermediate annealing + precision straightening", their dimensional tolerance is strictly controlled within grades H7-H8. Whether it is outer diameter, wall thickness, or straightness, they can accurately match the requirements of design drawings. This means that in the assembly of key components such as hydraulic cylinders and pneumatic cylinders, seamless connection can be achieved without additional cutting processes, fundamentally avoiding assembly failures caused by precision deviations. At the same time, the cold-drawing process also makes the metal grains of the tubes denser, forming a natural wear-resistant layer on the surface. Combined with subsequent phosphating and anti-rust treatments, their wear resistance is improved by more than 30% compared with ordinary hot-rolled tubes, and their service life can be extended to 2-3 times in transmission scenarios with high-frequency friction.

       For scenarios with higher precision and more stringent wear resistance requirements, Jianlida's honed tubes provide a better solution. Through the dual grinding processes of "rough honing + fine honing", the inner hole finish of honed tubes can be as low as Ra0.2μm - Ra0.4μm, with the inner wall as smooth as a mirror. This not only reduces the flow resistance of hydraulic oil and cooling fluid, lowering equipment energy consumption, but also significantly reduces friction and wear between components. In addition, high-quality carbon steel such as Grade 45 is selected as the material. After quenching and tempering heat treatment, the tensile strength of the tubes can reach more than 600MPa. Even under high-pressure and heavy-load working conditions, they can maintain stable mechanical properties, effectively avoiding problems such as leakage and deformation caused by wear.

      For enterprises, choosing high-precision and high-wear-resistance tubes is not merely a "procurement upgrade", but more importantly, an optimization of production efficiency and costs. Take an enterprise with an annual output of 5,000 hydraulic equipment units as an example. After using Jianlida's cold-drawn tubes, due to the compliance with precision requirements, the time consumed in the assembly process was reduced by 20%, and the rework rate dropped from 15% to less than 1%. At the same time, the extended wear-resistant service life of the tubes reduced the annual replacement frequency from 4 times to 1 time, cutting the procurement and maintenance costs of tubes per equipment unit by nearly 40%—these tangible benefits are the core value of solving the "precision troubles" and "wear worries".

      If you are still affected by insufficient tube precision and poor wear resistance in production, it's time to change your perspective: choose high-quality tubes that truly match your working conditions, and let professional products help you overcome pain points.
