What are Tees and Crosses?
Tees and Crosses are steel pipes protected by an inner ceramic lining made from high-alumina ceramic (typically high-alumina where specified), used to protect equipment from abrasive and impact wear. High-alumina ceramic gives hardness and chemical stability that defeat abrasion. In mining, cement, steel, power-plant ash handling, chemical processing and lithium-battery material plants, they extend equipment life and cut maintenance.
What are Tees and Crosses used for?
They convey abrasive slurries, ash, tailings and mineral concentrates where bare steel would erode in months. Common in mining, cement, steel, power-plant ash handling, chemical processing and lithium-battery material plants.
What material and properties make Tees and Crosses effective?
High-alumina ceramic gives hardness and chemical stability that defeat abrasion. These properties let Tees and Crosses outlast steel and rubber in abrasive service.
Why choose Tees and Crosses over steel or rubber alternatives?
Tees and Crosses beat unlined steel or rubber on abrasive duties: steel erodes in months and can contaminate product, while rubber gouges under lump impact. Tees and Crosses hold dimension, cut downtime and typically last 5–10× longer in mining, cement, steel, power-plant ash handling, chemical processing and lithium-battery material plants.
How do I select and specify Tees and Crosses?
Choose monolithic lining for small/medium diameters and smooth flow, tiled (mosaic) for large diameters and field repair; specify alumina for abrasion or RBSiC/SiSiC for heat and corrosion.
Are Tees and Crosses suitable for both slurry and dry powder?
Yes. Ceramic-lined pipe handles abrasive slurries, ash and tailings as well as dry powders and dust, protecting the bends where steel fails first. FIRSTAR sizes them to your line.
