Module from the Refractory and Insulation Curriculum curriculum.

Module 7 - Hot Insulation Installation · Learning Objectives · 1. Size pipe sections vs blocks vs blankets based on geometry · 2. Apply 50% staggered joints on multi-layer insulation · 3. Specify banding: 1/2" stainless, 12-in centers typical · 4. Select jacketing: aluminum for outdoor, stainless for corrosive · 5. Install weatherproofing + seal joints to reduce CUI risk · Insulation Fabrication Types
