Filling the annulus between concentric tubes with resin

Concentric conduits are supplied for the purpose of minimizing heat transfer from within the inner conduit through the outer conduit. The air gap or annulus around the inner conduit is filled with a resin mixture which is mixed with vermiculite and mineral fiber to form a slurry. The slurry is pumpe...

Beschreibung
Zusammenfassung:	Concentric conduits are supplied for the purpose of minimizing heat transfer from within the inner conduit through the outer conduit. The air gap or annulus around the inner conduit is filled with a resin mixture which is mixed with vermiculite and mineral fiber to form a slurry. The slurry is pumped into an open end of the annulus to fill the annulus and enhance the heat insulation characteristics of the concentric conduits.
