M S pipe lined basalt
M S pipe lined basalt - industrial steel pipe
Cast basalt lined steel pipes are widely used in abrasive conveying systems such as mining, power plants, cement and steel industries.
Cast basalt lined steel pipes are high-performance composite pipelines designed for transporting highly abrasive materials such as fly ash, coal powder, mineral slurry, tailings, sand and industrial bulk solids.
These pipes combine the structural strength of carbon steel with the extreme hardness of cast basalt lining, making them ideal for long-term operation in severe wear environments.
In industries such as mining, thermal power generation, cement production and metallurgy, conventional steel pipelines often suffer from rapid erosion and frequent maintenance requirements.
The cast basalt lining is produced by melting natural volcanic rock at high temperatures above 1250°C, forming a dense crystalline structure with excellent abrasion resistance.
This structure provides a smooth, hard internal surface that significantly reduces wear caused by high-speed particle flow.
As a result, service life is significantly extended compared with standard carbon steel pipes.
A cast basalt lined steel pipe is a composite pipeline consisting of an outer steel shell and an inner cast basalt lining. The steel layer provides mechanical strength and pressure resistance, while the basalt lining protects against abrasion and erosion.
This combination makes it suitable for transporting highly abrasive media under demanding industrial conditions.
In slurry and ash conveying systems, high-speed solid particles continuously impact the inner pipe wall, causing progressive erosion.
This leads to thinning of the steel wall, leakage, and eventual pipeline failure.
Cast basalt lining eliminates this issue by providing a hard, wear-resistant barrier.
