Bimetal Wear-Resistant Pipes
A steel outer pipe with a high-chromium white cast iron lining: high wear resistance for severe abrasion, with corrosion resistance and reliable bonding between the layers.
Overview
Bimetal wear-resistant pipes combine a steel outer pipe with a high-chromium white cast iron lining. The steel body provides structural strength and toughness, while the cast lining provides abrasion and corrosion resistance, so the pipe suits duties where corrosive media and particle erosion occur together.
Where wear resistance is the primary concern, a heat-treated high-chromium cast iron lining with a martensitic matrix can be selected.
Excellent corrosion resistance
The high-chromium cast iron lining (KmTBCr26Mo3CuRe) brings corrosion resistance to the pipe alongside its abrasion resistance.
Superior shock resistance
Withstands both mechanical and thermal shock.
Easy installation and connection
Can be cut and welded on site, which keeps installation flexible.
High pressure resistance
Withstands pressures up to 4.0 MPa, and the lining stays bonded to the steel outer wall.
Structure & shapes
Straight pipes are produced by centrifugal casting, which gives a dense cast lining bonded to the steel outer wall. Elbows and specially shaped fittings are also available.

Working conditions
These are the duties this product is built for. Final selection depends on the measured conditions at your site — send them and our engineers will review the application rather than apply a single material rule.
- Severe abrasive wear with moderate impact; impact response is grade dependent
- Fine and coarse solids
- Abrasive media that also carry a corrosive component, such as ceramic slurry
Applications
Mining & Mineral Processing
Mining and mineral processing convey highly abrasive slurries and solids — mineral slurries, tailings, concentrates and backfill. Wear concentrates where flow changes direction and where solids travel at speed, so pipe, elbow and tee selection must follow the actual operating conditions rather than a single material rule.
Typical media: Mineral slurries, tailings, concentrates, and backfill.
Cement, Ceramics & Building Materials
Cement, ceramics and building-material handling moves both dry powders and granules and wet media — cement, clinker, slag and limestone powder on one side, and gypsum slurry, ceramic slurry and ceramic mortar on the other. The two states wear pipework differently and must be evaluated separately.
Typical media: Cement, clinker, slag, limestone powder, and ceramic mortar.
Power & Coal
Power and coal handling moves both dry media — pulverized coal and fly ash — and wet media such as ash slurry and coal slurry. Dry and wet conveying impose different wear and corrosion conditions, so each stream is evaluated on its own terms.
Typical media: Pulverized coal, fly ash, bottom ash, and coal slurry.
Steel & Metallurgy
Steel and metallurgy handling moves coarse, hard and highly abrasive solids — ore fines, coke fines, sinter, slag and metallurgical dust. Wear is driven by particle hardness and shape as much as by velocity, so liner selection follows the measured duty rather than a single material rule.
Typical media: Ore fines, coke fines, sinter, and metallurgical dust.
Chemical Industry
Chemical and process duties combine abrasion with corrosion — slurries, process dust and abrasive media that attack the pipe wall chemically as well as mechanically. Suitability depends on the chemical properties of the conveyed medium and on product purity requirements, not on wear resistance alone.
