Cast Basalt Composite Elbow
Cast Basalt Composite Elbow - pipe elbow fitting
Steel pipes with cast basalt lining combine the strength of steel with the exceptional wear resistance of cast basalt, providing long service life in abrasive material conveying systems.
A steel pipe with cast basalt lining consists of an outer steel shell and an inner lining made from fused cast basalt segments. The steel pipe provides mechanical strength and pressure resistance, while the cast basalt lining protects the internal surface from abrasion, erosion, and chemical attack.
The basalt lining is manufactured by melting selected volcanic basalt at temperatures above 1250°C and then casting and crystallizing the material to form an extremely hard wear-resistant structure.
This dual-layer design significantly extends pipeline service life and minimizes downtime caused by wear-related failures.
Steel pipe with cast basalt lining is a highly durable wear-resistant piping solution designed for transporting abrasive slurries, powders, ash, ores, minerals, and bulk materials. Combining the structural strength of carbon steel with the exceptional abrasion resistance of cast basalt, these pipes provide a long-lasting and economical solution for demanding industrial applications.
Cast basalt lined steel pipes are widely used in mining, power generation, cement manufacturing, steel production, dredging projects, and chemical processing facilities where conventional steel pipelines suffer from rapid wear and frequent maintenance.

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.
