It is general used in oil refining,petrochemical,chemical and natural gas industries for hydroprocessing,hydrotreating,as well as dehytration etc.the product is often used in fixed bed reactors where a temperature range from 100℃ to 500℃.inert ceramic balls are also a standard item for the desulphurization process.
Through the exclusive manufacturing process,inert balls obtain a better stability and homogeneity.ie.The mass test of crush strengh indicated that the average crush strengh of 19mm inert ball is well above 540kgs,much higher than the industrial universal standard equivalent 430kgs.
