ORION-03 Circulating and Non-circulating Firing Head

ORION-03 Hydraulic Firing Head is used to initiate tubing conveyed perforating systems. It is activated by applying hydraulic or tubing pressure depending on the type of FH housing.

The non-circulating Firing Head GS ORION-03-...-00 (FH housing without circulating ports) doesn`t allow wellbore fluid to safely circulate into the tubing through tubing space.

The circulating firing head GS ORION-03-...-01 (FH housing with circulating ports) allows wellbore fluid to safely circulate into the tubing through tubing space.
