TongBall Tantalum Valve Balls represents the pinnacle of acid corrosion technology (up to 250°C/482°F). Through professional powder metallurgy, forming and welding techniques, the processing difficulties of this high-density active metal have been successfully overcome. The valve ball products finally made are almost inert to all kinds of acid media except hydrofluoric acid and high-temperature concentrated alkali.The product is an optimal solution for the treatment of concentrated sulfuric acid, nitric acid, hydrochloric acid and chlorine-containing media in the fields of chemical, pharmaceutical and hydrochloric acid synthesis.
