Product Description
Lined Ceramic Wear-Resistant Pipe is a composite pipe lined with high-purity alumina ceramic (Al₂O₃). Through a special process, the ceramic is bonded to a steel pipe or a rubber layer. It is suitable for conveying highly abrasive and corrosive materials such as slurry, ash, and coal powder. Its wear resistance is over 10 times that of manganese steel pipe, significantly reducing the frequency of downtime and replacement.
Lined Ceramic Wear-Resistant Pipe consists of three layers:
Outer layer: Q235/304/316L seamless steel pipe (pressure-bearing)
Middle: High-strength epoxy adhesive (heat-resistant to 120°C)
Inner layer: 92%-95% Al₂O₃ monolithically sintered ceramic rings/sheets, hardness HRA ≥88, Mohs 9. Sintered at 1700°C, the lining ceramic has a density of 3.7g/cm³, a compressive strength of≥850 MPa, and a flexural strength of≥290 MPa. The ceramic and steel pipes are bonded using a dual-metal mechanical joining and adhesive bonding process to ensure zero detachment under high-speed erosion.
Key Features
Ceramic thickness: 3–25 mm available, with customizable reducers, elbows, tees, and Y-pieces
Diameter range: DN50–DN1200 mm
Operating temperature: -50°C–350°C (special adhesive for heat resistance)
Connections: Flanges, welding, quick connectors, Victaulic clamps
Roughness: Ra ≤ 0.2 μm, resulting in low fluid resistance and low scaling

FAQ:
Q1: Will ceramics shatter under high-speed particle impact?
A: Reserve a 3mm rubber buffer layer between the ceramic ring and the steel pipe to absorb impact; There is no record of rupture under the condition of particle velocity ≤ 35 m/s.
Q2: Can we make wear-resistant bent pipes?
A: It can be bent with various radii ranging from R=1.0D to 5D, and the ceramic pieces have a dovetail interlocking structure that never falls off.
Q3: How to check the quality of the lining?
A: Before leaving the factory, each pipeline undergoes 100% endoscopic testing and a 10 MPa water pressure test, with a testing report attached.
Q: What is the service life of wear-resistant ceramic pipes?
A: Under normal operating conditions, its service life can reach 5-10 years, and the specific service life may vary depending on the severity of the operating conditions. Under special working conditions with severe wear and corrosion, it can also ensure stable use for 2-3 years.
Q: Is installing wear-resistant ceramic pipes complicated?
It's not complicated. Due to its light weight, the installation process is relatively simple, and suitable installation methods such as welding and flange connection can be selected according to the site conditions. We can also provide professional installation guidance services for customers.
Q: What extreme environments can the product adapt to?
A: It can adapt to extreme environments such as high temperature (up to 750 ℃), strong corrosion (various acidic and alkaline media), and high wear (such as transporting high-hardness granular materials), and can operate stably in complex industrial conditions.
