Refractory and Insulation Curriculum
Ins Design
Module from the Refractory and Insulation Curriculum curriculum.
Module 6 - Insulation Design · Learning Objectives · 1. Compute heat loss per unit length: Q/L = 2*pi*k*deltaT/ln(Do/Di) · 2. Apply personnel protection: surface T < 140F (140F = 3 M rule) · 3. Apply energy conservation: economic thickness typical for cost payback · 4. Specify jacketing: aluminum, stainless, galvanized · 5. Select flanged joint insulation (removable) per IPE-EP-11-3-6 · Recommended Insulation Thickness (2" NPS CS, 10 mph, Ambient 80F)
