Description
Underbalance Sub (UB) 2 3/8" and 2 7/8", available for 2.5K, 5K, or 10K pressure ratings.
Assembly or components required for the complete refurbishment of the underbalance assembly, ensuring reliable sealing and optimal performance in TCP (Tubing Conveyed Perforating) operations.
Kit Contents
- Frangible glass disc or 99% alumina dome — certified, with thicknesses calculated according to the desired pressure
- HNBR 90 sealing rings — resistant to temperatures and aggressive media
- Thread locking compound — for secure fastening and prevention of accidental loosening
