Ceramic sleeve relining (wear-resistant ceramic double pipe) (wear resistance, long lifespan)
■Outstanding Features We use fine ceramics with a very dense structure as the inner pipe material, which provides excellent wear resistance. Compared to plating and thermal spraying, it has a thicker wall (5mm to 15mm) and boasts a very long lifespan. The ceramic sleeve is also shaped and fired to match the curvature of the bend pipe. There are almost no joints or steps, allowing for smooth transport without causing turbulence. There is no concern about peeling, which is often a worry with chip lining.

basic information
■Details of Processing Technology This is a ceramic double pipe that has a fired ceramic sleeve inserted into the piping and fixed with a specialized non-shrink mortar (serving as both a cushion and adhesive). It demonstrates excellent performance as a wear-resistant measure for the inner surface of pipes, such as in the bend piping of powder and bulk material transport lines. It shows overwhelming wear resistance and chemical resistance compared to basalt (melt-cast products made from basalt) and high-chromium cast iron. As for the material of the ceramic inner pipe, in addition to the standard specification of 92% alumina, options include 99% alumina, alumina-zirconia, and silicon nitride intermediate materials, with non-shrink mortar for room temperature (up to 250°C) and high-temperature non-shrink mortar (up to 750°C) tailored to the required heat resistance. For the outer pipe, in addition to the standard SGP pipe, combinations with stainless steel pipes, heat-resistant steel pipes, and FRP (lightweight + chemical-resistant specifications; in the case of FRP, it is directly laminated and molded onto the ceramic sleeve) can be made. We can also manufacture 90° elbows, 45° elbows, T-pipes, Y-pipes, reducers, and more, in addition to straight pipes and bend pipes. ■Delivery Time (varies by quantity and size) 1 to 3 months.
