Cast basalt lined elbows are heavy-duty wear-resistant pipe fittings designed to withstand severe abrasion, erosion and impact in industrial conveying systems.
Cast basalt lined elbows are specially engineered wear-resistant pipe fittings designed for abrasive material conveying systems. By combining a high-strength steel shell with an ultra-hard cast basalt lining, these elbows provide outstanding protection against abrasion, erosion and impact wear.
Elbows are typically the most heavily worn components in a pipeline because material flow changes direction at these points, creating concentrated impact and turbulence. Cast basalt lining significantly extends service life compared with conventional steel elbows.
These fittings are widely used in mining, power generation, cement production, steel manufacturing, dredging and bulk material handling industries.
The cast basalt lining is produced by melting selected volcanic basalt at temperatures above 1250°C and crystallizing it under controlled conditions. The resulting material exhibits excellent hardness and wear resistance.
The smooth internal surface also reduces friction and minimizes material accumulation, improving conveying efficiency and reducing maintenance requirements.
Basalt lined elbows are available in various angles, diameters and connection types to suit different pipeline configurations.
In abrasive conveying systems, elbows often experience wear rates several times higher than straight pipe sections. Continuous particle impact at directional changes rapidly erodes ordinary steel fittings, resulting in frequent replacements and costly downtime.
Cast basalt lined elbows provide a highly durable wear-resistant solution that greatly extends service life while reducing operating costs.

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.
