Characteristics:
AL2O3 ceramic tubes have excellent conductivity,high machinery strength and high-temperature resistance, wear-resistance, corrosion resistance, impact & brush resistance, smooth wall of interior and exterior,airflow unobstructed,long service life and reduced maintenance ,can resist to the acid,high temperature,corridion and static electricity.
Usage:
AL2O3 ceramic tubes is widely used in the electronic industry,minery industry,metally industry,chemistry industry and so on.The alumina tube is a ideal wear-resistance material for delivering the sand,mine,ash dregs and molten aluminium.
Wear resistant AL2O3 ceramic tubes are developed for conveying all kinds of stereoplasm materials.Mainly used as the lining in the pipeline of conveying ore fines,cement,coal and other hard material.
AL2O3 ceramic tubes are widely used as wear-resistant linings in the system and mechanical equipments of coal transportation, material handling, milling, ash discharging and dedusting for coal-fired power plant, steel, cement, metallurgy, coal, mine and chemical industry.
Advantage:
AL2O3 ceramic tubes are of big size,complicated shape,difficult sintering,little gap,good bulk property,easy installation and long service life.
AL2O3 ceramic
tubes of Zibo Taisheng industry & trade Co.ltd is typed by HIP..The
materials can resist to the acid,high temperature,corridion and static
electricity. We can produce the almina tube with different sizes according to
the customers' enquirements.
