FILL/ FLOW SUB
Product Series: TCP FF 1000 ***
The LRI fill / flow sub allows the production tubing to fill with fluids while running in the hole, and with hydrocarbons after perforation.
A glass disk, held in place with a snap ring, prevents scale and debris from getting to the firing head. The disk is located above the bottom of the slot in order to allow well fluids to also fill the tubing below and equalize pressure across the disk.
Large slotted openings provide maximum flow area for circulating fluids and post-perforation production.
The LRI fill / flow sub is reusable, easily redressed with a redress kit, available at your local LRI distribution location.
