Reverse Circulation Junk Basket

The TIANHE Reverse Circulation Junk Basket (RCJB) is engineered to retrieve all types of small junk objects from the wellbore efficiently and safely. The tool utilizes a reverse circulation system that directs drilling fluid flow in a manner that prevents debris from falling back into the hole while reducing the possibility of pulling a wet string during fishing operations.

The RCJB is especially effective for recovering:

• Metal fragments
• Milling debris
• Bit cones
• Slips
• Bearings
• Hand tool fragments
• Small junk materials

During operation, reverse fluid circulation carries debris into the basket chamber where the junk is retained securely for retrieval to surface. When fitted with an optional magnet insert, the RCJB can additionally function as a magnetic junk catcher for ferrous materials.

Manufactured from high-strength alloy steel and precision-machined components, the RCJB provides reliable performance in demanding drilling, milling, and fishing applications.
