L-shaped circulating sliding sleeve
The L‑type circulating sliding sleeve establishes a passage between the casing and the production tubing. It can be easily opened or closed. Multiple sleeves can be run in a single string, and with the accompanying wireline‑operated switching tool, several sleeves can be opened or closed simultaneously. External connections on the circulating sliding sleeve allow for tie‑in to surface lines during gas‑lift operations.
