Wear Resistant Ceramic Tubes achieve core performance of high wear resistance, acid and alkali corrosion resistance and high temperature endurance through their ceramic linings. They are widely applied in mining, metallurgy, electric power and other industries, covering scenarios such as hard particle conveying, high-temperature flue gas discharge and corrosive medium transmission. To effectively extend their service life, efforts can be made in the following aspects:
(1) Regular inspection of appearance and connecting parts is the basic point of operation and maintenance.
Before each commissioning, check the pipe wall for cracks, damages or corrosion traces, with focus on vulnerable sections under severe scouring such as elbows and tees, to confirm the ceramic lining is free from peeling or penetrating damage. At flange positions, examine the aging state of sealing gaskets and the tightness of bolts, and deal with problems in time to avoid medium seeping into gaps and causing corrosion to the metal substrate.
(2) Controlling the temperature and flow rate of the conveying medium is a key measure.
Although Wear Resistant Ceramic Tubes have favorable high-temperature tolerance, long-term over-temperature operation will reduce the bonding strength between the lining and the substrate. It is recommended to control the medium temperature within a reasonable range (generally ≤ 800℃) via temperature control devices. Meanwhile, adjust pump parameters according to actual working conditions to regulate medium flow rate, so as to avoid continuous scouring of pipe walls by high-speed hard particles and slow down the wear rate of the ceramic lining.
(3) Good internal cleaning and external anti-corrosion treatment is an important guarantee.
When conveying media containing hard particles, flush the pipeline interior regularly to clear residual and accumulated particle impurities. For pipelines out of service for a long time, drain all internal medium thoroughly and blow-dry the inner wall with compressed air. For outdoor pipelines, apply anti-corrosion coatings on the outer side of the metal substrate to prevent rain and moisture from corroding the substrate.
Overall, the failure of Wear Resistant Ceramic Tubes mostly results from cumulative wear, chemical corrosion and external force impact. Targeted maintenance measures can greatly slow down the wear process. For complex working conditions, pipeline design can be optimized according to medium characteristics to further give play to their performance advantages, realizing longer service life and higher comprehensive cost-effectiveness.
