Niobium tubes, with their high melting point, strong corrosion resistance, excellent cold working performance and superconducting properties, play a key role in many fields with strict requirements for material performance.
In the chemical industry, a large number of high-temperature, high-pressure and highly corrosive media (such as sulfuric acid, hydrochloric acid, nitric acid, organic acids, etc.) are involved. Ordinary metal pipes (such as steel, copper) are prone to corrosion and failure. However, the corrosion resistance of niobium pipes (especially in non-oxidizing acids) can perfectly meet this demand.
Manufacturing inner lining tubes for reaction vessels: Used for chemical reactions in strong acid environments (such as organic synthesis and chemical raw material preparation), to prevent the medium from coming into contact with the container body and causing corrosion.
Heat exchanger tube bundle: In scenarios of heat transfer in high-temperature acid solutions (such as sulfuric acid concentration and acid and alkali wastewater treatment), niobium tubes can not only resist corrosion but also maintain good heat conduction efficiency.
Corrosive liquid conveying pipeline: It is used for conveying high-concentration acid, alkali solutions or industrial fluids containing corrosive impurities, ensuring the long-term stable operation of the pipeline and reducing maintenance costs. Core advantages: In concentrated hydrochloric acid and concentrated sulfuric acid at 100-200℃, the corrosion rate of niobium tubes is much lower than that of stainless steel (the corrosion rate can be controlled below 0.1mm/year), and their service life is 5-10 times that of ordinary pipes.
