Ceramic-lined composite steel pipes are composite pipelines with a wear-resistant layer internally added for heavily worn areas in engineering applications, serving the purposes of energy conservation, emission reduction, wear resistance, and corrosion resistance.

Based on varying wear conditions, different materials are selected for the ceramic-lined composite steel pipe linings. These include wear-resistant ceramic-lined pipes (lined with alumina trioxide, silicon carbide, zirconia, nitride silicon, selene, aluminum nitride, boron nitride, etc.); wear-resistant alloy pipes; turtle shell mesh wear-resistant pipe fittings; steel-rubber wear-resistant pipes; steel-plastic wear-resistant pipes; wear-resistant cast stone pipes; and wear-resistant self-propagating composite pipelines. Rare earth alloy wear-resistant tubes.

Wear-resistant ceramic composite pipelines are fundamentally different from traditional steel pipes, abrasion-resistant alloy cast steel pipes, cast stone pipes, and steel-plastic, steel-rubber pipes, etc. The outer layer of the ceramic-lined composite steel pipe is a seamless steel pipe, while the inner layer is made of alumina. The hardness of the alumina layer reachesThe HV1100-1400, equivalent to tungsten carbide, boasts a wear resistance 20 times higher than carbon steel pipes. The anti-wear property of the ceramic-lined composite steel pipes primarily relies on the alumina layer, which is only a few millimeters thick, representing a qualitative leap compared to the wear-resistant cast steel pipes and cast stone pipes, which rely on both composition, structure, and thickness for wear resistance.

Abrasive-resistant ceramic composite pipes quickly capture the market, not only due to their high quality and excellent performance, but also because of their superior performance-to-price ratio compared to other wear-resistant, corrosion-resistant, and heat-resistant pipes. In terms of ceramic-lined composite steel pipes of the same specifications and length, the weight of abrasive-resistant ceramic composite pipes is only about half that of wear-resistant alloy cast steel pipes, resulting in a reduced cost per meter of construction.The cast stone pipes weigh only one-third of the traditional ones, reducing the cost per meter by 5%-10%; the ceramic-lined composite steel pipes, used in corrosive or high-temperature environments, are priced at only a fraction of stainless steel pipes or nickel-titanium tubes.
