    Frequently asked questions

    We use advanced cold-drawing technology to ensure high precision. Our standard OD and WT tolerance is ±0.02mm. For specialized medical or instrumentation applications, we can achieve an ultra-tight tolerance of ±0.01mm.

    SS304 is cost-effective and suitable for general industrial and food-grade use. However, if your application involves high-corrosion environments (e.g., marine, chemical, or medical implants), SS316L is highly recommended due to its added molybdenum (Mo) for superior pitting resistance.

    Yes. We control the internal surface roughness strictly. Our Bright Annealed (BA) tubes typically have an internal roughness of Ra ≤ 0.4μm - 0.6μm, preventing clogging and ensuring high-purity transmission for chromatography and laboratory equipment.

    Absolutely. We provide professional secondary processing including precision cutting, chamfering, and deburring. Every piece is inspected to ensure the ends are flat, sharp, and 100% burr-free, making them ready for immediate assembly.

    We provide specialized ultrasonic cleaning and degreasing services. Tubes can be delivered "Oil-Free" and meet the cleanliness standards required for oxygen systems, medical devices, and analytical instruments.

    Protection is our priority. We pack capillary tubes in heavy-duty PVC tubes or reinforced cardboard cylinders, which are then placed into fumigated wooden cases. This "Double-Layer Protection" ensures zero deformation during sea or air freight.

    For standard sizes in stock, the MOQ is only 10 meters (or 1-2 spools). For custom-made specifications (specific material or thickness), the MOQ is generally 50-100 kg or based on a minimum length, depending on production feasibility.
