Abstract
A cellular glass system for an outer surface of a pipe or vessel. The insulation system has an outer surface and an inner surface and comprised of segments of cellular glass. A sealant is provided at the interface between the individual cellular glass segments and is configured to limit water intrusion and prevent corrosion.
Claims15
A cellular glass insulation system comprising a plurality of cellular glass insulation segments and a low viscosity sealant,
- wherein the cellular glass insulation segments have a length, side joint sections, an inner pipe bore, and end joint sections,
- wherein the low viscosity sealant is positioned along the length of the cellular glass insulation segment at an interface between the side joint section and the inner pipe bore, and on at least one end joint section;
- wherein the low viscosity sealant has an un-aged, as manufactured viscosity of 300,000 cPoise to 80,000 cPoise.
A method of insulating a pipe, the method comprising
- providing a first cellular glass insulation segment, a second cellular glass segment, and a low viscosity sealant,
- each of the cellular glass insulation segments having a length, an inner pipe bore, side joint sections extending the length of the cellular glass insulation segment between the inner pipe bore and an exterior surface of the cellular glass insulation segment of at least one of the cellular glass insulation segments;
- applying the low viscosity sealant along an interface between the inner pipe bore or vessel and at least one side joint section;
- applying the low viscosity sealant on at least one end joint section;
- positioning the cellular glass insulation segments about the exterior of a pipe or vessel;
- wherein the low viscosity sealant has an un-aged, as manufactured viscosity of 300,000 cPoise to 80,000 cPoise.
A cellular glass insulation system comprising a plurality of cellular glass insulation segments and a low viscosity sealant,
- wherein the cellular glass insulation segments have a length, side joint sections, an inner pipe bore, and end joint sections,
- wherein the low viscosity sealant is positioned along the length of the cellular glass insulation segment at an interface between the side joint section and the inner pipe bore, and on at least one end joint section;
- wherein the low viscosity sealant has an un-aged, as manufactured viscosity of below 225,000 cPoise to 80,000 cPoise.
