Performance characteristics of alumina ceramic wear-resistant tube:
(1) Extremely high wear resistance The ultra-high molecular weight is more than 2 million, the wear index is small, and the wear resistance is 6.6 times higher than that of ordinary alloy steel. Greatly improve the service life of the pipeline.
(2) Very high impact resistance, this product meets the GB1843 standard, and the impact toughness value of this product is the highest among the existing engineering plastics
(3) Alumina ceramic wear-resistant pipe has good corrosion resistance. This product can resist the corrosion of strong chemical substances.
(1) Good self-lubrication. Good self-lubrication. The friction coefficient is small. The surface of the alumina ceramic wear-resistant tube does not adhere or scale.
(2) Unique low-temperature resistance This product has excellent low-temperature resistance and can work at temperatures from -50°C to 80°C for a long time.
(3) Excellent resistance to cracking. The best resistance to environmental stress cracking. The resistance to environmental stress cracking is >4000h, which is more than twice that of PE100.
