High-Purity Stainless Steel Coaxial Tube - Ultra-Hygienic, Corrosion-Resistant & Thermal-Efficient Solution for Critical Fluid Transfer"
Engineered for industries demanding uncompromising purity and durability, this high-purity stainless steel Coaxial Tube is designed to meet stringent sanitary and operational standards. Its dual-layer construction provides unmatched protection against contamination, thermal loss, and mechanical stress, making it ideal for pharmaceutical, food & beverage, semiconductor, and chemical processing applications.
Key Features:
Ultra-Hygienic Design: Electropolished inner surface (Ra ≤ 0.4µm) prevents bacterial growth and ensures easy cleaning, complying with FDA, EHEDG, and 3A standards.
Corrosion Resistance: Made from 316L/304L stainless steel with passivation treatment, resistant to acids, alkalis, and high-salinity environments.
Thermal Efficiency: Vacuum-insulated annular gap minimizes heat transfer, maintaining consistent fluid temperatures (hot or cold) with minimal energy loss.
Leak-Proof Safety: Hermetic seal between inner and outer tubes eliminates cross-contamination risks, even under high pressure (up to 25 bar).
Customizable Configurations: Available in various diameters (10mm-200mm), lengths, and connection types (tri-clamp, weldable ends, flanges).
