Gasholder Seal

Our gasholder seals are compatible with Wiggins type dry gasholders, up to 100,000 m3, used in steel plants, but also for conical gasholder in biomass and chemical plants. Our gasholder seals are resistant to converter gas and BOF (Blast Open Furnace) that can be found in Wiggins gasholders.
 
To ensure the highest level of quality the process is fully integrated, from material development in our Hutchinson research and innovation centre, through rubber production, calendering, manufacturing and inspection to assembly supervision.
 
The design of the membrane and its hot vulcanized welds give the membrane a special flexibility and resistance, limiting constraints and areas of accelerated aging. This robustness enables an extended service life around 20 years, reduces maintenance interventions and the corresponding risks.
