Industrial Abrasion Defense
Cast basalt tile lined pipes deliver durable wear and corrosion resistance with smooth basalt interior—ideal for ash, slurry, and abrasive flow systems.
Basalt tile lined pipes are commonly used in industries such as power generation, mining, cement, steel, and chemical processing, where the transportation of abrasive materials is required.
Cast basalt tile lined pipes feature a steel outer shell and an interior lined with tightly fitted cast basalt tiles—hexagonal or rectangular—embedded and sealed with cement mortar or bonding agents. The basalt tiles are produced by melting volcanic rock at ~1,300 °C, casting them into precise geometric pieces. These are installed in curved or straight pipelines, bunkers, and chutes, providing a seamless internal lining.
A naturally occurring volcanic rock, basalt is one of the toughest natural ceramic materials and can be precast to provide a wide range of products, including tiles, pipe linings and guttering shapes. Up to four times harder than other stone products, basalt is non-porous, highly abrasion and chemical resistant. Melted to 1280°C and cast into steel or sand moulds to produce flat or radial tile shapes to lay as floors, basalt can be retrofitted and installed to protect the bottom sections of existing ovoid or round brick or concrete pipes.
From 50mm up to 3000mm NB basalt is produced as full 360° pipeline systems encased in steel shells for retrofit or new build giving up to 200 years superior life in service. Basalt offers excellent service and high protection from maintenance like jet washing and chemical cleaning to remove blockages caused by waste build up.
Our factory can manufacture and line anything economically transportable by road, covering a diverse range of plant components such as pipelines, cyclones, hoppers, trough chain conveyors, and more.
We are also adept at repairing worn-out components. If necessary, we can perform any required steel metalworking. In such cases, you will receive a refurbished, repaired, and surface-treated plant component equipped with wear protection, ready for installation.
With the most common sizes available in stock, we can promptly deliver various wear protection materials. This allows sufficient time for us to refurbish plant components in our factory during a planned plant shutdown.
Far exceeds unlined steel, AR plate and most ceramic linings in severe sliding abrasion.
Resists almost all acids, alkalis and saline solutions (except HF).
Continuous service up to 350–450 °C (grade dependent).
Prevents material adhesion and reduces pressure loss & energy consumption.
Steel outer shell allows normal welding. Damaged sections can be cut out and replaced individually without dismantling the entire line.
