Scale Traps

Scale Traps

Down-flow processes often carry metallic contaminants or scale, which can quickly plug the top surface of a vessel’s catalyst bed. Our screens effectively increase the surface area of the bed which disperses the scale over a wider area, thus extending the bed’s useful life. This is easily done by placing an array of screens in the upper part of the catalyst bed where, depending on screen size and placement, they can increase the total effective bed area by up to 400 percent and trap most of the contaminants present in the flow. 

Not only do the screens resist normal operating stresses, but they can also survive being dumped with the catalyst. And when it’s time for routine cleaning, they can be vigorously wire brushed or blasted without breaking or tearing. 

Standard scale traps range from

  • OD : 102 mm / 4.0 in.  to 168 mm / 6.6 in. 
  • Length :  300 mm / 11.8 in. to 1 m / 39.4 in.
  • Slot opening : 0.5 mm / 0.020 in. to 1.5 mm / 0.060 in. 
  • Total screen open area can be as high as 50 percent
