Ceramic Lined Pipes and Fittings
Wear- and Corrosion-Resistant Ceramic Lined Pipes and Fittings
In industrial fluid control and conveying systems, abrasive and corrosive media can rapidly damage conventional valves and pipe fittings. Frequent replacement and repair increase maintenance costs, while unplanned shutdowns reduce production efficiency and raise the total cost of operation.
Plinduo supplies ceramic-lined elbows and other fittings for highly corrosive and abrasive service. The outer shell can be carbon steel or stainless steel, with segmented welded elbows or one-piece hot-bent construction selected for the service conditions. The lining can be a monolithic ceramic liner or a mosaic tile system.

Monolithic Ceramic Lined Pipe Construction
- Steel Pipe Shell:Stainless steel or carbon steel pipe can be specified. Elbows are formed by one-piece hot bending for a smooth internal flow path, clean appearance and higher pressure capability.
- Adhesive Filler Layer:A ceramic-grade epoxy adhesive provides high shear strength, good workability and strong bonding. Adhesive grades for 150°C, 250°C or 350°C service can be selected; the ceramic adhesive is typically white.
- Ceramic Lining Layer:Common tile sizes include 7.5×17.5 mm, 10×10 mm, 100×50 mm, 100×80 mm, 100×100 mm and 120×80 mm, with thicknesses from 5 to 30 mm. Complex steel geometries can use multiple tile sizes; joints are filled with ceramic adhesive to keep the step at less than 1 mm.
From outside to inside, a monolithic wear-resistant ceramic lined pipe consists of the steel shell, adhesive filler and ceramic layer. The finished ceramic and adhesive faces are flush with the flange sealing face.
Elbow Lining
The ceramic lining is curved to match the elbow radius. Each ceramic segment uses a socket connection; after firing at 700°C, the segments are pre-assembled and then installed as a complete lining inside the steel pipe.
Tile-Lined Ceramic Construction
The tile-lined design combines ceramic tiles, ceramic-grade weld studs, inorganic adhesive and a high-toughness steel backing plate. Stud-welded versions secure the ceramic to steel equipment and use a high-temperature inorganic adhesive for long-term operation without aging or delamination.
