Vanadium Tubes
Vanadium Tubes
Vanadium is a rare, ductile transition metal renowned for its high tensile strength, excellent fatigue resistance, and remarkable ability to retain properties at extreme temperatures. Our vanadium tubes are fabricated from high-purity vanadium (≥99.95%) and customized vanadium alloys (e.g., vanadium-chromium, vanadium-titanium) tailored to specific application requirements.
We adopt a multi-step production process including vacuum melting, hot extrusion, cold drawing, and precision annealing, ensuring the elimination of impurities and uniform grain structure. The tubes feature a smooth inner/outer surface finish, free from cracks, porosity, or other defects that compromise performance.

Applications
Aerospace & Defense
Used in rocket engine nozzles, aircraft hydraulic systems, and missile guidance components, where high strength and temperature resistance are critical.
Nuclear Energy
Serves as cladding tubes for nuclear fuel rods and heat exchanger tubes in nuclear reactors, thanks to its low neutron absorption cross-section.
Chemical Processing
Applied in corrosive fluid transfer pipelines, such as for sulfuric acid, hydrochloric acid, and other aggressive chemicals.
Medical Devices
Utilized in high-precision medical instruments and implantable devices, benefiting from its biocompatibility and corrosion resistance in human body environments.
Energy Storage & Power Generation
Employed in vanadium redox flow batteries (VRFBs) as electrolyte circulation tubes, enabling efficient large-scale energy storage.
Quality Assurance & Certifications
Our vanadium tubes are manufactured in compliance with ASTM B500, DIN 17865, ISO 683-11 and other international standards. Our production facility holds ISO 9001 certifications, ensuring strict quality control throughout the entire production cycle.
Each tube undergoes rigorous testing, including dimensional inspection, mechanical property testing (tensile, fatigue, hardness), corrosion resistance testing, and non-destructive testing (ultrasonic, eddy current, radiographic testing). Test reports are provided with every shipment to ensure product quality meets customer requirements.
