Ceramic-Lined Wear-Resistant Pipe

Ceramic wear-resistant pipes are high-performance industrial pipes made from a composite of metal and ceramic.They are widely used in power generation,metallurgy,mining,coal,and chemical industries,and are suitable for transporting abrasive particles and corrosive media.These products comply with the DL/T680-1999 standard of the power industry.

The outer layer of the ceramic wear-resistant pipe is steel,while the inner layer is made of corundum ceramic(Al₂O₃)or silicon carbide(SiC),manufactured through centrifugal casting or self-propagating methods.The Mohs hardness reaches 9.0,providing wear resistance over 10 times that of quenched steel and corrosion resistance more than 10 times that of stainless steel.The temperature range covers-50°C to 700°C,with excellent acid-and alkali-resistance and anti-scaling properties.Pipes can be connected via welding or flanges,with a weight reduction of 20–50%compared to traditional pipes,reducing project costs by 20–40%.In slurry transport in mining,the service life can be increased approximately 5 times,and in applications such as power plant ash discharge or aluminum transport,metal contamination can be avoided.They are ideal for high-wear environments such as thermal power plant ash handling and coal preparation plant gangue transport.

Excellent Wear Resistance:

The wear resistance of ceramic wear-resistant pipes is over 10 times that of high-chrome wear-resistant cast iron pipes.A 5 mm thick ceramic layer provides an actual service life equivalent to a 50 mm thick wear-resistant cast steel pipe.

Corrosion Resistance:

By selecting different wear-resistant ceramic materials,the pipes exhibit superior corrosion resistance against various corrosive media,including acids,alkalis,salts,and halide salts.

High-Temperature Resistance:

The ceramics themselves can withstand temperatures above 1200°C.Through proper design and composite methods,ceramic wear-resistant pipes can operate long-term in a temperature range of-50°C to 800°C,making them especially suitable for high-temperature burners and equipment lining.The internal ceramic lining has high strength and hardness,providing excellent wear and corrosion resistance.

Cost Reduction:

Ceramic wear-resistant pipes are primarily used for transporting solid-liquid two-phase flows containing abrasive particles and corrosive media,replacing expensive stainless steel pipes,high-chrome cast steel pipes,and hard alloy wear-resistant pipes.They help lower project costs while extending service life.With high cost-performance,these pipes reduce maintenance and replacement costs and save time.

Lightweight and Easy to Install:

The manufacturing process is simple,and the pipes are lightweight,making transportation and installation convenient.
