    Ceramic lined pipe Properties

    Wear-resistant ceramic composite pipe, full name ceramic liner composite steel pipe, is a kind of ceramic composite steel pipe.

    Ceramic (Corundum: a-Al2O3) lined abrasion resistant straight pipe and fittings are lined with highly abrasion resistant ceramic by SHS -------Self-propagating High-temperature Synthetic process.

    A small amount of iron also remains in the ceramic layer. There is a thin equiaxed grain area of alumina near the steel pipe wall, and then alumina was grown in form of dentrite to the surface of ceramic layer.

    Physical Properties

    Ceramic lined pipe

    When abrasive material is transported through steel pipe in mining applications, typically as pumped slurry, the pipe can quickly be eroded from the inside out, which in more extreme cases can result in pipe leaks and even failure, or significant maintenance costs and downtime for pipe replacement.

    Section of the composite pipe

    Microstructure of ceramic layer

    Mechanical Propertie:

    FeAl2O4 distributes among alumina dentrite. Although the ceramic layer was solidified from one end to another end of a pipe, the microstructure of ceramic layer was almost uniform throughout the whole length of the pipe.

    Resistance to thermal shock

    A composite elbow was used
    in a mining plant for about
    fifty thousands hours.

    Hoop Strength

    Hoop strength is the resistance against radial pressure. The strength of the ceramic -lined steel composite pipe is 300 to 500MPa.

    Compression-Shear Strength

    Compression-shear strength is the bonding strength at the interface between the ceramic layer and the steel pipe. The compression-shear strength of the ceramic-lined composite pipe is 15 to 20MPa.

    Resistance to Mechanical Shock

    The ceramic layer does not crack or flake off when the composite pipe receives a mechanical shock.

    Resistance to Thermal Shock

    The ceramic layer does not crack or flake off when heated to 800℃ and then quenched.

    Resistance to Abrasion:

    The ceramic-lined steel composite pipe has exceptional resistance to abrasion. Its service life in materials transportation with hard abrasives is more than 20 times longer than in common steel pipe.

    For these abrasive applications, mild steel pipe is not tough enough to stand up to the abuse for more than a year or two. As a result, maintenance engineers are seeking superior piping alternatives to reduce maintenance and prolong system life, at a price point that will not significantly impact the budget.

    The general servicelife of common steel elbow is about 700 hours.

    Good Weld Ability
    The ceramic-lined steel composite pipe can be joined by welding the steel pipe layer.
    Light Weight

    The ceramic-lined steel composite pipes are lighter than alloy pipes, cast iron pipes, and cast stone pipes, which reduces the expense of transportation and makes the pipes easier to install.

    Good weld ability

    The relative weight of the
    composite pipe is about
    40-50% lighter than that of the
    caststone pipe
    Convenient Installation

    The ceramic-lined steel composite pipes can be easily connected by welding, or with flanges and soft easy connectors.

    Convenient installation

    The composite pipes have good corrosion-resistant. There is no evidence of corrosion filling the composite pipes with bitter for one year (left), but the common steel pipe under the same condition is corroded seriously (right).

    Ceramic liner composite pipe is different from traditional seamless steel pipe, wear-resisting alloy cast steel pipe, cast stone pipe, steel plastic pipe and steel rubber pipe.

    Abrasion Resistant Pipe Solutions

    Conveying highly abrasive materials, steel piping systems are under constant attack often over long distances.


    Because the outer surface behaves like mild steel, the product can be cut and welded with proper procedure in the field, configured into a variety of fittings, and can accept the standard end options of flanges, weld rings and couplings.
