Lined Ceramic Wear-Resistant Pipe

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

Installation precautions

Handle with care: Ceramic-lined composite steel pipes have high hardness but limited toughness, so they should be handled with care during transportation and installation to avoid serious collisions, especially to prevent metal instruments from directly hitting the ceramic layer on the end face to avoid damage.

Directional installation: The installation of bent pipes has directionality. During installation, the direction indicated by the arrow on the surface of the bent pipe should be consistent with the flow direction of the conveying medium, and the longer end of the bent pipe should be the outlet direction.

Accurate docking: When installing pipelines, the pipelines should be aligned with the centerline and leveled to ensure accurate docking at both ends. The displacement of both ends should be controlled within 1.0 millimeters to ensure the sealing and stability of the connection.

Connection method:

Flexible pipe sleeve connection: When using a flexible pipe sleeve connection, the insertion length of the inner two ends should be adjusted symmetrically to reduce expansion and contraction problems caused by differences in thermal expansion coefficients. The expansion gap can be determined according to local working conditions or design department requirements, but it can generally be reduced to 3-5mm.

Flange connection: When using a flange connection, the flange end face must be flush with the composite pipe end face to ensure the tightness and stability of the connection.

Welding connection: The composite pipe has excellent welding performance and can be connected by welding. When welding, the groove generally adopts a 45 ° -60 ° "V" - shaped edge without leaving any gap. It is recommended to use low current intermittent welding to avoid the adverse effects of high temperature generated during the welding process on the ceramic lining.

Ceramic lining inspection and installation: Before installation, a detailed inspection of the ceramic lining should be carried out to ensure that it is intact and the dimensions meet the design requirements. During the installation process, attention should be paid to the flatness and alignment quality of the ceramic lining to ensure its wear resistance and service life.

Sealing treatment: After the installation of the ceramic lining is completed, the interface should be sealed to prevent medium leakage.

Quality inspection and acceptance: During and after the construction process, quality inspection and acceptance work should be carried out on the pipes and ceramic lining, including visual inspection, dimensional measurement, pressure testing, etc., to ensure that the construction quality meets the requirements.
