Wear resistant ash pipeline system lined with cast basalt for power plant and industrial ash handling applications.
Cast basalt lined ash pipelines are engineered for thermal power plant ash handling systems, where continuous transport of high-temperature, high-abrasion ash materials causes severe pipeline wear.
These systems are widely used in fly ash and bottom ash conveying lines, where conventional steel pipes suffer rapid erosion due to high-speed particle impact.
The cast basalt lining provides a highly durable internal surface that significantly extends pipeline service life.
Ash conveying systems operate under harsh conditions including abrasive particles, moisture, thermal cycling and continuous operation.
Cast basalt lined pipes ensure stable long-term performance by combining steel structural strength with extreme wear resistance.
This makes them a preferred solution for modern power plant ash handling networks.
A cast basalt lined ash pipeline is a wear resistant transport system used to convey fly ash, bottom ash and other combustion residues from boilers to storage or disposal areas.
The system consists of steel pipes and fittings internally lined with cast basalt material to resist severe abrasion.
Fly ash particles are fine but extremely hard and abrasive, especially when moving at high velocity in long-distance pipelines.
At bends, elbows and junctions, particle impact increases dramatically, causing rapid wall thinning.
Without proper lining, pipelines require frequent replacement and cause costly plant downtime.

Cast basalt is a highly wear-resistant and corrosion-resistant lining material widely used in pipes, chutes, bunkers, cyclones, and hoppers.
Usage
Installation
Cast basalt has become the global standard for ash slurry pipelines in fossil-fuel power stations and other heavy industries. It significantly extends equipment service life in environments with severe abrasion and corrosion.
It is commonly used as a cost-effective lining material for steel, cast iron, rubber, or polyurethane equipment, offering 5–10 times longer service life than traditional materials.
Is cast basalt suitable for high-temperature ash?
Yes, it performs well under typical ash conveying temperature ranges.
Which parts wear fastest in ash pipelines?
Elbows, bends and junctions are the most critical wear points.
Can this system be used in retrofit projects?
Yes, it is commonly used for upgrading existing ash pipelines.
Ceramic lined pipe is made through self-propagating high-temperature synthesis (SHS) technique.
Cast basalt lined steel pipe is composed by lined with cast basalt pipe, outside steel pipe and cement mortar filling between the two layers.
Ceramic tile lined pipes have very uniform coating of specially formulated ceramic material that is affixed to the inner of the pipe.
The material of the rare earth alloy wear-resistant pipe is ZG40CrMnMoNiSiRe, which is also the grade of rare earth alloy steel.
Tubes Erosion Shields are used to protect boiler tubing from the highly erosive effects of high temperatures and pressures thereby greatly extending tube life.
The ASTM A213 T91 seamless tubes are primarily used for boiler, superheater, and heat-exchanger.
