Vee-Wire Scallops

Johnson Screens' Vee-Wire scallops are a highly effective means to direct inlet flow in radial flow processes. Compared to a single large outer basket, installation and repair can be much faster and simpler with these individual screens.

Unique Selling Point

Johnson Screens' Vee-Wire scallops have distinct operating advantages. Vertical slots, for example, allow the catalyst to ride up and down during operation without abrading. Slots can be as narrow as 0.3 mm / 0.012 in. to retain small-size catalyst.

Insights

Made of welded Vee-Wire and rods, our Vee-Wire scallops have exceptional resistance to bending, twisting or collapsing - all essential qualities when faced with extreme loads caused by expansion in temperature cycling operations. Buckling, a problem in very tall reactors, is virtually eliminated as is damage caused during installation. Once installed, the screens are easily maintained. 
Their special slot design virtually eliminates plugging. Despite the narrowness of individual slots, the scallop arrangement has a much higher total open area than a single large outer basket or perforated plate scallops of the same size. 
This increased open area translates directly into reduced pressure drop and enhanced process efficiency. Vee-Wire scallops are available in any width or length, and in a wide variety of metal alloys.
