Copper and copper alloy, in aqueous solution, hydrochloric acid and other non oxidizing acid, organic acids (such as: acetic acid, citric acid, fatty acid, lactic acid, oxalic acid), ammonia removal than the various alkali and oxidation of organic compounds (such as: oil, phenol, alcohol etc.), have a good corrosion resistance; therefore, in the petrochemical industry for manufacturing contact corrosive medium containers of various copper, vapor-liquid filters, wire mesh demister, filters and other devices.

I plant the production of brass, vapor-liquid filter, copper vapor-liquid filter is widely used in pressure vessels, machinery manufacturing, automotive, electrical, light industry, defense industry
