Common Applications Include:
1.Severe Service Ball Valves & Plug Valves: The protection tube would be placed around the valve stem. It prevents the corrosive, abrasive, or high-temperature fluid from eroding the metal stem, ensuring smooth operation and preventing seizures or leaks.
2.Knife Gate Valves: Used in industries like mining and pulp & paper to handle abrasive slurries. The tube protects the gate and stem mechanism from rapid wear.
3.Sensor Protection: It can serve as a thermowell or a sheath for temperature sensors (thermocouples, RTDs) or pressure sensors inserted into a pipeline. The alumina ceramic protects the sensitive sensor from chemical attack and physical damage.
4.High-Temperature or Corrosive Environments: Ideal for industries like:
•Chemical Processing: Handling acids, alkalis, and solvents.
•Petrochemical: In refineries with corrosive hydrocarbons.
•Power Generation: In systems with high-temperature steam or flue gases.
•Mining and Mineral Processing: For abrasive slurries and tailings.
•Steel and Metal Production: In high-heat furnaces and handling molten metals.
