For engineers

Specification language, material properties and a freeze calculator for Dragon Jacket prefabricated pipe insulation.

Pipe insulation specification

A three-part CSI section for prefabricated, factory-encapsulated pipe insulation. Copy any article into your project manual, or download the full section in Word or PDF.

Technical data

Properties of the insulating core, the polyurea jacket and the high-density inserts, with the ASTM test method behind each value.

Pipe freeze calculator

How long water in a stopped line takes to reach 32 °F, for your pipe, wall thickness, ambient temperature and wind. Compare up to three insulation systems side by side.

Shorter timelines
Longer lifespan

Send us the drawings or a line list with the pipe sizes, service temperatures and exposure, and we’ll quote the insulation. Questions about a detail or a spec section come straight to our engineers.
