• Eaturing high-precision CNC turning or micro-grinding technology, this product is processed with uniform and smooth micro-chamfers (typical angle of 15°-45°)​ at the junctions of the inner and outer walls.

• We not only focus on the precise cutting of the outer wall but also perform ultra-fine mirror polishing​ on the inner wall chamfers.

• The chamfer angle and curvature radius, optimized using Computational Fluid Dynamics (CFD) software, can guide fluids to pass through the tube in a smoother and more concentrated flow state. 

FAQs:

Q: What is the specific impact of the internal/external chamfered design on fluid transmission?

A: The internal/external chamfered design, especially the smooth transition on the inner wall, can significantly reduce turbulence and dead spots inside the lumen. The smooth bevel avoids the tiny vortices or fluid stagnation that might be caused by traditional right-angle edges, thereby ensuring the continuity and purity of liquid or gas transmission. This is particularly crucial for scenarios with high fluid dynamics requirements, such as precise infusion, continuous irrigation, or gas sampling.

Q: How is the machining precision of this tube guaranteed? Which medical departments or specific devices is it suitable for?

A: Our Internal/External Chamfered Tubes are manufactured using high-precision CNC lathes or micro-grinding processes, ensuring that the chamfer angle, edge smoothness, and wall thickness consistency reach micron-level (μm). Due to its combination of low friction and high passability, it is widely used in minimally invasive interventions, endoscopic guidance, extracorporeal circulation line interfaces, laboratory sampling catheters, and various medical device connection tubes requiring precise docking.

Q: Will the chamfering increase the risk of infection or affect the product's sterilization effect?

A: On the contrary. Our chamfered design undergoes strict biocompatible mirror polishing treatment​ (Ra value can be below 0.2μm), resulting in an extremely smooth surface that is not prone to retaining bodily fluids or particulate matter, which inherently reduces the risk of microbial growth. Furthermore, the tube body is typically made of medical-grade stainless steel or polymer materials, fully compliant with high-temperature steam sterilization (e.g., autoclaving) or ethylene oxide (EtO) sterilization​ requirements. The smooth nature of the chamfered edges actually helps improve the penetration efficiency of sterilization media, ensuring thorough sterilization.
