🔍 Key Concepts

• Castable insulation application methods and typical uses aboard ships • Differences between castable, brick, and block in terms of installation, strength, and temperature resistance • What shipyards and repair crews usually prioritize when lining boilers, uptakes, or thermal equipment with insulation

💭 Think About

• Think about how castable insulation is physically applied compared to brick or block. Does it come as a rigid shape or something else? • In ship construction and repair, what is usually the main reason for choosing castable products over shaped refractory materials? • Which of the listed properties is the MOST commonly cited benefit in practice when choosing castable over brick or block?

✅ Before You Answer

• Compare which material normally has higher structural strength: castable vs brick/block. • Consider which materials are generally preferred for very high-temperature refractory linings. • Ask yourself: when working in tight or irregular spaces on a vessel, which material form would most improve installation time and labor cost?
