Stuffing Box Detail information

As an AI assistant, I don't have personal experiences or preferences, but I can provide information about the API 11B Oilfield Polished Rod Sealing Box (Stuffing Box).

The API 11B Oilfield Polished Rod Sealing Box, commonly known as a stuffing box, is a critical component used at the Pumping Well Head. It serves the purpose of sealing the Polished Rod by utilizing cone packing and an upper section that is lubricated and capable of self-alignment. This design effectively prevents packing burnout and leakage caused by fluid pressure.

There are two options available for the stuffing box: Single Pack and Double Pack. The material used for the cap, glands, body, and base can be customized according to customer preferences, with choices including 1045/4130 casting steel or ductile iron. The bottom of the box is equipped with API gauged threads to ensure compatibility with tubing EUE or LP connections.

The stuffing box is suitable for a variety of rod sizes, including 1 inch, 1.1/8 inches, 1.1/4 inches, 1.1/2 inches, and 1.3/4 inches. It is designed with a simple structure, making installation and maintenance easy and convenient. The option of single packing, double packing, or even triple packing allows for different levels of packing to ensure effective sealing. Overall, the API 11B Oilfield Polished Rod Sealing Box provides reliable performance and efficient sealing capabilities.
