Basalt lined pipes
for Japanese steel plants
Reinforced backpack type cast basalt lined elbow for heavy-duty abrasive slurry and ash pipelines.
Backpack wear resistant cast basalt lined elbows are heavy-duty reinforced pipeline fittings designed for extreme abrasion and high-pressure slurry transport systems.
Unlike standard elbows, this design features an external steel reinforcement structure (backpack type) that strengthens the elbow body against mechanical stress and impact loads.
The internal cast basalt lining provides outstanding resistance to abrasion and erosion caused by high-velocity solid particles.
This combination makes it suitable for the most demanding industrial environments, including mining, power plants, cement plants and long-distance slurry pipelines.
It is especially effective in high-wear elbow positions where conventional fittings fail prematurely.
The structure significantly extends service life and reduces maintenance frequency.
A backpack cast basalt lined elbow is a reinforced pipe elbow that combines an internal wear-resistant basalt lining with an external steel reinforcement layer.
The external "backpack" structure acts as a mechanical support shell, improving pressure resistance and structural stability.
In high-pressure slurry systems, elbows are subjected to both internal abrasion and external mechanical stress.
Standard elbows may deform or crack over long-term operation under combined loading conditions.
The backpack reinforcement distributes stress and enhances structural integrity.

Backpack structure improves mechanical stability.
Basalt lining protects high-impact zones.
Reduces failure in critical elbow positions.
Minimizes downtime and replacement cycles.
Cast basalt can be used for the lining of pipework, chutes, bunkers, cyclones, and hoppers.
It has become the global standard in areas such as ash slurry pipework, often used at fossil-fuel power stations. It is an all-round cost-effective and adaptable lining material that extends the life of equipment in pipe or tile form where affected by erosion.
Cast basalt is well-proven in a variety of industries as a cost-effective, long-lasting lining material used to extend the operating life of equipment manufactured or lined with lower-wearing materials such as steel, cast iron, rubber, and polyurethane.
Cast basalt lined steel pipe, as both a wear—resistant and corrosion—resistant materials, the transport properties of wear or corrosion of materials, after thirty years of practical verification, cast basalt lined steel pipe can be well done.
Cast basalt is also used in cement plants for making air separators, chain conveyor, silica hoppers, nozzles, coal hoppers, cement hoppers, cyclones, raw mill ducts, chutes, thick slurry lines, mixers, grate cooler housing, coal ventury etc.
What does "backpack" mean in this elbow?
It refers to an external reinforcement steel structure around the elbow body.
Where is it used?
High-pressure slurry and ash conveying systems in mining and power plants.
Is it better than standard elbows?
Yes, it provides both higher strength and longer wear life.

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.
