Stuffing Box Detail information
The API 11B Oilfield Polished Rod Sealing Box, commonly known as a
stuffing box, is a crucial component installed at the Pumping Well
Head. Its main purpose is to seal the Polished Rod using cone
packing and a lubricated upper section. This design ensures
self-alignment, prevents packing burnout, and effectively seals
against fluid pressure leakage.
The stuffing box is available in two variations: Single Pack and
Double Pack. Customers have the flexibility to choose between using
1045/4130 casting steel or ductile iron for the cap, glands, body,
and base, depending on their specific requirements. The bottom of
the stuffing box is equipped with API gauged threads, designed to
match tubing EUE or LP connections.
These stuffing boxes are suitable for a range of 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 a simple structure, making
installation and maintenance hassle-free. The option of single
packing, double packing, or even triple packing ensures optimal
sealing effectiveness, offering reliable performance and efficient
sealing capabilities.
