Fine, abrasive powders, combined with a pneumatic conveying system, meant that even small tears or gaps in the traditional clamped flexible connectors at the plant caused dust leakage.
The hose-clamp seals did not perform well under pressure, and with 25 different fittings, manual error with installing the existing clamp & hose connectors to the incorrect length also added to the leakage problems.
The real risk of explosion in the plant meant that AkzoNobel were keen to find a fitting that would provide a durable, sealed system and also allow them to standardize their fittings across the plant.
