Stuffing Box Detail information
The API 11B Oilfield Polished Rod Sealing Box, also known as a stuffing box, is an integral component installed at the Pumping Well Head. It serves a crucial function of sealing the Polished Rod through the utilization of cone packing and a lubricated upper section. This innovative design ensures self-alignment, prevents packing burnout, and effectively prevents any leakage caused by fluid pressure.
The stuffing box is available in two variations: Single Pack and Double Pack, offering customers the flexibility to choose the most suitable option. Depending on specific requirements, customers can opt for either 1045/4130 casting steel or ductile iron for the cap, glands, body, and base of the stuffing box. The base of the stuffing box is equipped with API gauged threads, designed to seamlessly match tubing EUE or LP connections.
These stuffing boxes are suitable for various rod sizes, including 1 inch, 1.1/8 inches, 1.1/4 inches, 1.1/2 inches, and 1.3/4 inches. They are characterized by their simple structure, facilitating hassle-free installation and maintenance processes. With the option to choose between single, double, or triple packing, optimal sealing effectiveness is ensured, providing customers with reliable performance and efficient sealing capabilities.
