High Purity Vanadium Tubes

High purity vanadium tubes are mainly used in the corrosion-resistant industry, although vanadium is present in all aspects of the industry, its environmental hazards should not be underestimated, the concentration of vanadium in natural water is very low, generally 0.01-20 ppb in river water, with an average of 1 ppb. seawater contains 0.9-2.5 ppb of vanadium. although the soluble vanadium content of water bodies is very low, the amount of suspended matter in water is very high. The deposition of suspended matter leads to the migration of vanadium in water to the substrate and purifies the water column. Vanadium in soils exists mainly in the VO3-anion state. The more oxidizing and alkaline the soil is the more easily vanadium forms VO3- ions. When the acidity of the soil increases, the VO3- ions are easily transformed into poly vanadate complex anions. They are all easily immobilized by clay and soil colloids and humus and become inactive, and vanadium is weakly mobile in the soil. The toxicity of vanadium metal is very low. Vanadium compounds (vanadium salts) are toxic to humans and animals, and their toxicity increases from the increase in atomic value and solubility of the compound, e.g. vanadium pentoxide is highly toxic and can cause respiratory, nervous system, gastrointestinal, and skin changes.                                                                                                                                                        The method of smelting metal with vanadium tube is that high purity vanadium ingot with diameter φ150-φ215mm is obtained by vacuum Electron beam melting metal vanadium block, and the external surface of vanadium ingot for a vehicle is polished. A vanadium rod with a diameter of φ50-φ125mm was cut out by sealed spark drilling and wire cutting. The inner wall, outer wall, and end face of vanadium tube blank are covered by cladding material and welded. Heating to 750-1000 degrees, heat preservation 1-2 hours, through the package of a vacuum tube, after the school's treatment of raw materials, directly with the surrounding pipe and machine-processed raw materials; The mass production of the target material of the raw material tube was realized by using and machining.              

In response to the hazards caused by vanadium, we should skin contact: remove contaminated clothing and rinse thoroughly with soapy water and water. Eye contact: Immediately flip open upper and lower eyelids and flush with running water for 15 minutes. Seek medical attention. Inhalation: Remove from the scene to fresh air and rinse the dust from the nose and throat with water. Seek medical attention. Ingestion: Seek medical attention for accidental ingestion. Symptomatic treatment.
