FAQ

Q: What is ceramic lining, and how does it work?

A: Ceramic lining involves bonding high-purity alumina (Al₂O₃) tiles to the inner surface of coal mill pipes. These tiles provide an ultra-hard, wear-resistant layer that protects the pipe from abrasive coal particles, extending its lifespan by 5-8 times compared to standard carbon steel pipes.

Q: How is ceramic lining installed?

A: The installation process includes:

Surface Preparation: Blasting the pipe interior to achieve a clean, rough surface.

Tile Bonding: Using high-temperature epoxy or mechanical interlocking to attach ceramic tiles.

Curing: Allowing the adhesive to cure under controlled conditions for maximum bond strength.

Inspection: Conducting ultrasonic testing (UT) to ensure no voids or defects.

Q: What types of pipes can be lined with ceramics?

A: Ceramic lining is suitable for:

Straight pipes (DN150-DN1200)

Elbows (30°-90°, all radii)

Tees and reducers

Complex geometries (custom designs available)

Q: What is the lifespan of ceramic-lined pipes?

A: Under normal operating conditions, ceramic-lined pipes last 5-8 years, compared to 6-12 months for unlined carbon steel pipes. Lifespan depends on factors like coal abrasiveness, flow velocity, and operating temperature.

Q: Can ceramic-lined pipes withstand high temperatures?
A: Yes, ceramic-lined pipes can withstand temperatures up to 1700°C, making them ideal for high-temperature applications such as coal mill outlet piping.

Q: Is the ceramic lining impact-resistant?

A: While ceramic sheets are extremely wear-resistant, they are less impact-resistant. For high-impact areas, we recommend:

Combined solutions: Add a steel backing plate to the ceramic lining for added strength.

Strengthen the design: Use thicker ceramic sheets or additional support structures.

Q: How do I know if my pipes need ceramic lining?

A:Signs that your pipes need wear protection include:

Visible thinning: Measured using ultrasonic thickness gauges.

Frequent leaks: Caused by wall penetration.

Increased maintenance costs: Due to repeated replacements.

We offer free wear inspections to assess your pipes and recommend the best solution.

Q: What is the lead time for ceramic-lined pipes?

A: Standard Products: 20-25 days.

Custom Designs: 30-40 days.

Urgent Orders: Expedited production available (additional cost).

Q: How are ceramic-lined pipes packaged and shipped?

A:Packaging: Wooden crates with foam cushioning to prevent damage during transit.

Shipping: Available via sea, air, or land, with FOB/CIF/EXW terms.

Delivery: Typically 25-45 days to major global ports.

Q: Can I get samples before placing a large order?
A: Yes, we provide free samples. Samples will be sent out within 7 working days.

Q: Is on-site installation supported?
A: Yes, we provide on-site installation guidance or outsourced installation services to ensure construction quality.
