Elbows, Pipes and Fittings Linings

Ceramic linings can extend wear life and improve performance when integrated into any transport piping where an abrasive material is being moved, whether this is via gravity feed, dense phase, dilute phase, slurry or vacuum conveying. In industrial environments where highly abrasive materials are pneumatically conveyed, unlined steel or rubber-lined elbows may wear out in a matter of weeks, resulting in an expensive cycle of downtime for frequent repairs and replacements.

Saint-Gobain Performance Ceramics & Refractories offers an ideal solution to this common wear problem. Its range of wear-resistant ceramic liners offers a unique combination of straightforward installation, exceptionally long service life, and low cost fabrication. A range of ceramic-lined elbows and liners are available specifically for this type of application.

Saint-Gobain Performance Ceramics & Refractories’ comprehensive product portfolio offers outstanding mechanical properties, superior wear resistance and excellent corrosion performance. Saint-Gobain Performance Ceramics & Refractories’ pipe fitting liners have been proven to last 5-10 times longer than steel alternatives, while consistently outperforming inferior ‘ceramic-lined’ products.

FAQ

Are Saint-Gobain Performance Ceramics & Refractories’ ceramic-lined fittings designed to match current pipe inner diameters?

Yes. Fittings are designed using a larger pipe size to ensure that the inner diameters remain consistent and that a material flow remains smooth across the flange joint. A range of end connections can be incorporated, allowing the expanded ceramic lined fitting to be assembled with the existing unlined piping.

Do ceramic-lined fittings reduce material flow by restricting the inner diameter or via increased friction?

No. Because Saint-Gobain designs the ceramic inner diameter to match the adjoining pipe, there is no increase in pressure. As ceramics are used in the piping, the surface will ‘polish’ and become smoother, further reducing the coefficient of friction in the liner.
