Power Plant Ceramic Patch Pipe High Hardness Alumina Ceramic Patch Pipe for

Product Specification

Product Description

Power plant material conveying systems handle fly ash, pulverized coal, limestone powder, and other abrasive media. Continuous sliding, particle impacts, and local turbulence can gradually wear through an unprotected steel pipe, especially at elbows, pipe inlets, diameter transitions, and other locations where the flow direction changes.

This power plant ceramic patch pipe uses wear-resistant alumina ceramic tiles installed inside a steel pipe. The steel shell provides structural support, while the ceramic lining protects the internal surface from direct abrasion.

The lining arrangement, ceramic thickness, fixing method, and steel pipe specifications are customized based on the conveyed material, particle size, velocity, temperature, pressure, and the actual wear position.

Where Does Pipe Wear Usually Start?

Wear is not always distributed evenly along the pipeline. In power plant conveying systems, local damage commonly begins at:

• Elbows and changes in conveying direction
• Pipe inlets where material enters at an angle
• Reducers and changes in internal diameter
• Flange ends and pipe connections
• Raised ceramic edges or uneven tile joints
• Areas exposed to concentrated particle impact
• Positions affected by unstable flow or local turbulence

A thicker ceramic lining alone does not guarantee a longer service life. The internal surface should remain smooth, the joints should be properly arranged, and exposed edges facing the incoming material should be avoided.

Technical Parameters

The values above are general references for the ceramic material. Final material properties, pipe dimensions, and lining construction are subject to the confirmed technical data sheet, drawing, and operating conditions.

Lining Structure

The composite pipe generally consists of:

• Steel outer pipe
• Bonding or fixing layer
• Wear-resistant alumina ceramic tiles

The ceramic tiles are arranged along the internal surface of the pipe to form a continuous wear-protection layer. Tile dimensions and arrangement are selected according to the pipe diameter and geometry.

For pipes with complicated shapes or relatively large diameters, ceramic tiles provide greater installation flexibility than integral ceramic sleeves. However, the number and condition of the tile joints must be carefully controlled.

Different fixing structures may be selected according to temperature, impact, vibration, and operating conditions. The final construction should be confirmed before production.

Five Design Details That Matter

Confirm the conveyed material, velocity, temperature, and actual wear position before selecting the lining.

Check the finished internal diameter because ceramic thickness reduces the available pipe bore.

Keep ceramic joints tight and smooth to avoid raised edges facing the material flow.

Protect flange ends, reducers, and connections from exposed steel edges or abrupt internal steps.

Select the fixing method according to temperature, impact, and vibration conditions.

Typical Applications

• Fly ash pneumatic conveying
• Pulverized coal conveying
• Coal handling systems
• Dust collection pipelines
• Limestone powder conveying
• Ash discharge pipelines

Wet slurry or corrosive conditions require separate evaluation of the steel material and fixing system.

Information Required for Quotation

Please provide the pipe drawing, quantity, conveyed material, particle size, velocity, temperature, pressure, pipe dimensions, ceramic thickness, and connection standard.

Packing and Delivery

Ceramic-lined pipes are packed in suitable wooden cases or secured on reinforced steel racks. Pipe ends and flange faces are protected during handling and transportation.
