The secondary insulation space to equaliz

The both insulation space to equaliz

The vapor dome space to equaliz

Detailed Explanation & Context

In Gaztransport & Technigaz NO 96 membrane containment systems, Invar membranes and perlite insulation boxes maintain cargo containment and thermal insulation.
