Which sealant is most commonly used on turbine casing joints?

• A. Epoxy resin
• B. Copalite
• C. Silicone sealant
• D. Neoprene

Answer: (B)

Copalite is the correct answer because it is specifically designed for use in high-temperature environments, making it well-suited for turbine casing joints, where heat resistance is crucial. Its unique formulation provides excellent adhesion, sealing capabilities, and durability against various operational stresses found in turbine applications. This characteristic is essential because turbine joints must withstand both thermal expansion and the pressure produced during operation without breaking the seal, which could lead to loss of efficiency or damage. In contrast, epoxy resin, silicone sealant, and neoprene may not provide the same high levels of thermal resistance and durability under the specific environmental conditions found in turbine operations. Epoxy resins can be prone to brittleness at high temperatures, while silicone sealant may not withstand the mechanical stresses involved. Neoprene, although versatile and used in various applications, does not typically excel in high-temperature settings, making Copalite the preferred choice for turbine casing joints.
