Door curtains on continuous heat treatment furnaces
Applications08 Sept 2026

Door curtains on continuous heat treatment furnaces

A continuous furnace cannot close its doors, so the curtain does the sealing: it limits air ingress, heat loss and oxidation at the entry and exit.

A class or B1 class insulation for a jacket
Selection08 Sept 2026

A class or B1 class insulation for a jacket

The insulating fill decides both heat loss and combustion class. A class is non-combustible; B1 is flame retardant and stops burning when the source is removed.

Jackets on hot water pipe: the condensation problem

Outdoors, a hot water pipe can still condense on its surface. A jacket without water resistance loses performance from the first wet season.

Silicone gaskets: what 200 C really means
Selection08 Sept 2026

Silicone gaskets: what 200 C really means

Standard silicone sheet is a -60 to 200 C material. Above that, the elastomer degrades; modified grades extend the range but not indefinitely.
