Cast Basalt Composite Heavy Calibre Pipe

Large Diameter Wear Resistant Pipeline

Heavy calibre cast basalt composite pipes are engineered for large diameter abrasive conveying in demanding industrial environments.

What Is a Heavy Calibre Cast Basalt Composite Pipe?

Cast basalt composite heavy calibre pipes are designed for large diameter, high-capacity conveying systems handling highly abrasive materials such as fly ash, bottom ash, mineral slurry, tailings and industrial bulk solids.

In power plants, mining operations and cement production facilities, main transmission lines often operate under high flow rates and continuous particle impact. Conventional steel pipelines in these conditions suffer from rapid wear and frequent failure.

The heavy calibre cast basalt composite pipe solves this problem by combining a high-strength steel shell with an ultra-hard basalt lining.

Due to its large diameter design, this type of pipeline is commonly used as the main trunk line in ash and slurry conveying systems, where stability and durability are critical.

The cast basalt lining is formed through high-temperature crystallization of natural basalt, resulting in excellent hardness and abrasion resistance.

It is particularly suitable for long-distance, high-volume abrasive transport systems.

A heavy calibre cast basalt composite pipe is a large diameter wear-resistant pipeline designed for transporting abrasive materials at high volumes. It consists of an external steel pipe and an internal cast basalt lining.

The structure ensures both mechanical strength for high-pressure operation and extreme resistance to abrasion from solid particles.

Wear Challenges in Heavy Calibre Pipelines

Even though large diameter pipes reduce velocity compared to smaller pipelines, they still suffer from severe wear due to continuous abrasive particle flow.

In main ash and slurry lines, long operating hours and high throughput result in constant erosion along the pipe wall.

Without internal protection, steel pipes require frequent replacement and cause costly system downtime.
