Ceramic Wear Liners for Ash Conveying – High Performance Abrasion and Corrosion Protection
Our ceramic wear liners are engineered using high-purity alumina ceramics, offering exceptional hardness and resistance to both abrasion and chemical corrosion. These liners are ideal for protecting steel pipelines in high-wear systems such as pneumatic fly ash conveying, slurry transportation, and mineral processing.
One of our core strengths is the ability to manufacture large-diameter ceramic lined pipes - up to 700mm in diameter- making us a leading supplier in this niche field.
Key Features
Outstanding Abrasion Resistance: Alumina ceramic lining offers up to 10 times the wear life of traditional steel pipes.
Effective Corrosion Protection: Resistant to acid, alkali, and chemical erosion, ensuring stability in harsh operating environments.
Customizable Size Range: From standard sizes to extra-large pipes (up to Ø700mm) for heavy-duty applications.
Enhanced Service Life: Significantly reduces maintenance frequency and downtime, improving operational efficiency.
Seamless Integration: Easy to install and compatible with most industrial pipeline systems.

| Density (g/cm) | 3.6~3.9 | 1.1~1.3 | 1.1~1.25 | 7.8~7.9 |
| Hardness | HRA 85-90 / Mohs scale 9 | Shore A 60-90 (soft) | Shore A 80-95 (elastic) | HRC 20-40 (prone to wear) |
| Flexural strength (MPa) | 250 ~ 350 | 5 to 20 (elastomer, non-flexural strength) | 20 to 50 (elastomer) | 300-600 (but prone to plastic deformation) |
| Operating temperature | -50℃ to +1400℃ (long-term ≤350℃) | -40℃ to +80℃ (heat-resistant rubber ≤120℃) | -40℃ to +80℃ (partial ≤100℃) | -50℃ to +450℃ (Poor oxidation resistance) |
| Wear resistance | ⭐⭐⭐⭐⭐ (20 to 50 times that of carbon steel) | ⭐⭐ (resistant to particle impact) | ⭐⭐⭐ (elastic cushioning and wear-resistant) | ⭐ (wear-prone) |
| Impact resistance | ⭐⭐ (brittle, afraid of direct impact from large pieces of material. but ZTA ceramic is impact-resistant. | ⭐⭐⭐⭐⭐ (high elastic buffer) | ⭐⭐⭐⭐⭐ (excellent elasticity) | ⭐⭐⭐ (plastic deformation) |
| Corrosion resistance | ⭐⭐⭐⭐⭐ (resistant to acids, alkalis and solvents) | ⭐⭐⭐ (chemical resistant rubber is required) | ⭐⭐ (resistant to weak acids and bases, afraid of strong acids and bases) | ⭐ (prone to rust) |
| Service life | 5 to 15 years + (high wear conditions) | 1 to 5 years (depending on the medium and wear intensity) | 2 to 6 years (better than rubber) | 0.5 to 3 years (short service life under high wear) |
| Installation and maintenance | Professional pasting/welding is required (low maintenance frequency) | Pasting/vulcanization (easier to replace) | Pouring/pasting (Medium replacement) | Welding (high replacement cost) |
| Main application scenarios | Pulverized coal pipes in power plants, slurry pipes in mines, and dust removal in steel mills | Desulfurization pipelines, mineral processing flotation cells, and chemical storage tanks | Cyclone, slurry pump, moderately worn pipeline | Ordinary non-corrosive low-pressure pipeline |
