This short presentation tells the story behind cellular glass pipe shell insulation and its intended use in industrial cryogenic tanks and piping. We walk through how the closed-cell foam glass structure works, show where pipe shells and boards are applied, and explain how the material performs in wet, condensing, and fire-sensitive service. Viewers will see the difference between cryogenic and building grades and learn which parameters matter when specifying insulation for cold lines, hot lines, and stainless steel systems.
