Ultimate Abrasion & Corrosion Defense
Steel pipes lined with high-performance silicon carbide ceramic to provide unmatched wear and chemical resistance in industrial pipeline systems.
Silicon carbide ceramic lined pipes combine heavy-duty carbon steel outer shells with thermally bonded silicon carbide ceramic liners, delivering top-tier abrasion and corrosion resistance. Engineered specifically for harsh industrial environments, these pipes excel at conveying high-density slurries, fly ash, chemical effluents, and abrasive media.
The ceramic liner is crafted from high-purity silicon carbide, known for its extremely high hardness, thermal stability, and chemical inertness. Once bonded to the steel tube using advanced high-temperature processes, the liner forms a seamless, durable barrier that prevents wear and protects against aggressive chemicals and cyclic thermal stress.
These abrasion-resistant ceramic tubes are ideal for industries such as power generation, mining, cement, chemical processing, and wastewater treatment. They stand up to high-pressure flow conditions and abrasive particle impact, significantly extending pipeline lifespan compared to unlined or elastomer-lined pipes.
Available in a wide range of diameters (e.g., DN50–DN1000+) and pressure ratings, connectors include flange, butt-weld, and expansion joints to support installation flexibility and accommodate thermal movement. The seamless ceramic-steel bond prevents liner delamination or cracking, even under high flow turbulence and sudden pressure fluctuations.
By choosing silicon carbide lined pipes, operators gain exceptional flow efficiency, longer maintenance intervals, and reduced total cost of ownership. These pipes maintain integrity under extreme temperatures, abrasive slurries, corrosive fluids, and cyclic stress, offering reliable performance in demanding applications.
Sunny Steel’s meticulous manufacturing and quality assurance processes—covering dimensional inspection, non-destructive liner testing, and pressure validation—ensure consistent, high-quality delivery tailored to your project specifications. Opt for ceramic lined steel piping when performance, durability, and uptime matter most in industrial fluid handling systems.

Other specifications of cast steel pipe lined with basalt can be manufactured according to customer technical requirements. Suitable for large-diameter basalt lining steel pipes with a nominal diameter greater than 800mm. Generally, according to the running status of the pipeline, different cement is used to fix the basalt brick inside the finished steel pipe to complete the basalt lining steel pipe. Its advantages are good wear resistance, wide range of use, basically not limited by the size of the pipeline and low cost of pipeline installation.
Cast basalt is a volcanic mineral material known for its exceptional abrasion resistance, complete impermeability to moisture, high compressive strength, and resistance to most acids and alkalis. It is entirely corrosion-proof, making it ideal for harsh industrial environments.
It is produced by melting selected natural basalt, crushed into 20–50 mm fragments, in shaft furnaces at approximately 1,300°C. The molten basalt is then cast and crystallizes into a uniform phaneritic structure, resulting in excellent hardness and wear resistance.
Cast basalt has a minimum hardness of 8 on the Mohs scale (diamonds are rated 10), making it extremely effective for abrasion and erosion protection.
Like other ceramics, it is sensitive to impact. Under normal service conditions, cast basalt withstands temperatures from -40°C to +350°C, but it should not be subjected to thermal shock.
Sizes: Cast basalt products come in the form of tiles, formed pieces, and segments. Straight pipes are spun-cast with nominal bores from 32 to 600 mm, wall thickness 20–30 mm, and standard lengths of 500 mm. Smaller bores, pipe segments with radii of 40–3000 mm, and special formed pieces are usually sand-cast. Steel molds can be used for higher volumes, producing 30–40 mm thick linings.
Cast basalt-lined pipes are widely used in abrasive and ash handling systems such as chutes, troughs, funnels, silos, dust collectors, rotary flow machines, conveyors, and feeders. In chemical plants, they can be used to line pickling tanks or store corrosive substances.
Customized specifications and shapes are available to meet specific project requirements.
Refined into a finely crystallized glass ceramic, Sunny Steel’s cast basalt linings offer extremely durable protection for static plants handling large volumes of abrasive or corrosive media.
Available in both pipe and tile form, cast basalt is ideal for wet material handling systems with lower impacts, such as coal chutes, ash sluiceways, and pipelines at power stations. It provides excellent resistance to wear, corrosion, and temperatures up to ~400°C.

Manufacturing Process
Cast basalt is a silicate crystalline material manufactured through a high-temperature refining process. It is produced using natural igneous rocks such as basalt, diabase, or selected industrial waste slag as the primary raw material.
These materials undergo melting, casting, controlled crystallization, and annealing, resulting in a dense, highly wear- and corrosion-resistant product.
A cast basalt lined pipe typically consists of three layers:
Cast basalt ceramic for abrasion and corrosion resistance
Steel pipe for structural strength
Cement mortar for bonding and chemical passivation
Composite Benefits: This composite structure ensures high durability, pressure resistance, and corrosion protection.
The cement mortar creates an alkaline environment on the inner steel surface, forming a passive protective film that prevents corrosion. Overall, the cast basalt lined pipe is ideal for transporting abrasive or corrosive media in complex operating conditions.
Elbows are designed with turning radii and center angles based on user requirements and share the same diameter series as straight pipes.
Silicon Carbide Ceramic Lined Pipe is widely used for lining pipework, chutes, bunkers, cyclones, and hoppers in severe abrasion environments.
Cast basalt lining has become a global standard in applications such as ash slurry pipework, particularly in fossil-fuel power stations. It offers an excellent balance of cost efficiency, durability, and adaptability.
It is well proven across multiple industries as a long-lasting wear lining material, extending equipment life compared with steel, cast iron, rubber, or polyurethane.
With over 30 years of practical application, cast basalt lined steel pipes have demonstrated outstanding resistance to both wear and corrosion.
In cement plants, it is commonly applied in air separators, chain conveyors, hoppers, ducts, chutes, nozzles, and related components.
