Cast Stone Lined Steel Pipe
Cast Stone Lined Steel Pipe - industrial steel pipe
Cast basalt composite pipes are widely used in power plants for ash handling, coal conveying and slurry transportation where severe wear conditions exist.
Cast basalt composite pipes are widely used in thermal power plants to transport abrasive materials such as fly ash, bottom ash, coal powder, desulfurization slurry and boiler ash. By combining a high-strength steel shell with an extremely wear-resistant cast basalt lining, these pipes provide reliable long-term protection against erosion, abrasion and chemical attack.
Modern power generation facilities continuously handle large volumes of solid particles and abrasive slurries. Conventional carbon steel pipelines often experience severe wear, particularly at high-velocity conveying points, resulting in leakage, maintenance downtime and costly replacements.
Cast basalt composite pipes are specifically engineered to overcome these challenges and provide a durable solution for harsh power plant operating conditions.
The cast basalt lining is produced by melting selected volcanic basalt at temperatures above 1250°C and then allowing controlled crystallization. The resulting material offers exceptional hardness, outstanding abrasion resistance and excellent chemical stability.
These pipelines are commonly installed in coal-fired power stations, biomass power plants, waste-to-energy facilities and industrial utility plants where abrasive material handling is an everyday operating requirement.
Straight pipes, elbows, bends, tees, reducers and custom fittings can all be supplied as part of a complete wear-resistant piping system.
Power plants transport large quantities of abrasive materials throughout their operating life. Fly ash particles, coal dust, bottom ash and limestone slurry continuously impact pipeline walls, creating severe erosion and abrasion.
Areas experiencing the highest wear rates typically include elbows, reducers, tees and high-velocity discharge sections. Without adequate wear protection, conventional steel pipelines can fail prematurely, leading to costly shutdowns and maintenance work.
Cast basalt composite pipes provide a practical and economical solution by creating a durable wear-resistant barrier between the conveyed media and the steel pipe wall.

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.
