Wedge Wire Scallops

Wedge wire scallops are important components of reactor internals. The
scallops are manufactured from Johnson filters and have a fan-shaped cross-
section, hence their name.

Wedge wire scallops are positioned against the reactor wall through expander
rings. The top of the scallops is sealed and the bottom is open, the lower
part is open and connected to the header at the bottom of the reactor. The
oil and gas discharged from each scallop are mixed in the header and flow
out from the oil and gas outlet.

Purpose: Collect or distribute flow. Retain catalyst and prevent catalyst
leakage in radial flow device.

The Johnson screen scallop is designed to optimize fluid dynamics, enhance
filtration efficiency, and elevate operational reliability in your
industrial processes.
