Oil Production API Standard Polished Rod Stuffing Box Customised
Stuffing Box Detail information
The API 11B Oilfield Polished Rod Sealing Box, also referred to as a stuffing box, is a vital component installed at the Pumping Well Head. Its primary function is to create a seal around the Polished Rod using cone packing and an upper section that is lubricated and capable of self-alignment. This design ensures the prevention of packing burnout and effectively seals against fluid pressure leakage.
The stuffing box is available in two versions: Single Pack and Double Pack. Customers have the flexibility to choose between 1045/4130 casting steel or ductile iron for the cap, glands, body, and base, based on their specific requirements. Furthermore, the bottom of the stuffing box is equipped with API gauged threads that are compatible with tubing EUE or LP connections.
These stuffing boxes are suitable for a variety of rod sizes, accommodating dimensions of 1 inch, 1.1/8 inches, 1.1/4 inches, 1.1/2 inches, and 1.3/4 inches. With a simple structure, they can be easily installed and maintained. The option of single packing, double packing, or even triple packing ensures the sealing effectiveness that guarantees reliable performance and optimum sealing efficiency.
