CASCADE'S ARMOUR PLATES ARE VULCANIZED - THEY CAN NEVER FALL OUT!

   
 

 

 

THE ARMOUR PLATE INSERTED INTO THE GASKET IS A CRUCIAL ELEMENT IN THE PERFORMANCE OF A REPAIR CLAMP AS IT PROVIDES THE FULL CIRCUMFERENCE SEALING CAPABILITY OF THE REPAIR CLAMP.   AS SUCH, IT IS ESSENTIAL THAT ARMOUR PLATES:

  • Be permanently fitted - to prevent being dislodged or falling out at any stage
  • Be perfectly sized - to avoid having gaps between the armour and the rubber at either or both ends of the armour plate
  • Provide a smooth transition from rubber to metal - so that the thickness of the sealing area at both ends of the armour plate conforms to the thickness of the rubber
 
  Problems encountered with glued armours
 

 

 

When an armour plate is glued either into or onto the gasket it can fall out or be dislodged, and the full circumference sealing capability of the clamp will be lost.

When an armour plate is glued into the gasket, it may not fit properly, leaving gaps or crevices at one or both ends that can cause low-pressure points.
(See Figure 1)

Under pressure these low-pressure points "sink" to fill the gaps shown in the schematic diagram, leaving a potential leak path between the pipe and gasket.

On the other hand, when armour plates are glued onto the gasket, or welded to the clamp's shell, they protrude, and there is no uniformity in the transition from rubber to metal
(see Figure 2)

The protruding armour plate will, under pressure, create low-pressure points and potential leak paths between the pipe and gasket.

 


CASCADE'S PERMANENT SOLUTION

Recognising the armour plate's crucial role, Cascade only fits gaskets where the armour plate has been vulcanised into the rubber at the time of moulding. This ensures:

  • that the armour plate in a Cascade repair clamp can never fall out - it is permanently fitted every time
  • that there are no gaps or crevices at either end of the armour plate - it fits perfectly every time
  • that the thickness of the sealing area at both ends of the armour plate conforms to the thickness of the rubber - a smooth transition from rubber to metal every time.
