Demanding conditions - reliable solutions

For distillation, the crude oil is first heated to around 350 °C (662 °F) and then broken down into individual products. Substances with a boiling point above this temperature become gaseous and rise in the distillation column.

High temperatures and different compositions of crude oils - which can also be corrosive (hydrogen sulfide + sulfur) and abrasive - are some of the greatest challenges faced by the sealing technology used in refinery distillation facilities.

We guarantee reliable sealing of the complete process chain in distillation facilities with our proven H75 and LL9 pusher seal types, while the MFLWT and MBS metal bellows seals are preferred for particularly high temperatures. High quality sliding materials such as Buka 22 (a silicon carbide material) and structural materials from Inconel® are used for metal bellows.
