Roller Kelly Bushings can be classed as two types based on different ways of drive, square drive, and pin drive. Also, they can be classed into three types based on different styles, heavy, medium, and light-duty. They are used for 17 1/2 to 49 1/2inch rotary tables. They are designed and manufactured according to API Spec 7K.
Sinker bars are an essential component in artificial lift systems used in oil extraction. They serve to provide additional weight to the sucker rod string, ensuring that the rod string remains straight and minimizing buckling. Sinker bars are manufactured from high-quality hot-rolled carbon manganese steel bars and conform to API Spec. 11B and AISI steel products manual specifications. These bars are available in various sizes, with different combinations of body diameter and pin sizes to suit specific applications.
Each sinker bar is designed with a reduced section on one end to facilitate elevator seating and lifting. The pin blanks undergo precise machining, and the dimensions are carefully gauged. To enhance durability and performance, the pin threads are cold-formed by rolling, which strengthens the thread against fatigue. A protective inhibitor lubricant is applied to each pin, and a thread protector is installed to ensure longevity. Additionally, an oil-soluble coating is applied to protect the bars from corrosion during storage.
Sinker bars are bundled securely to prevent handling damage during transportation, ensuring that they arrive in optimal condition. Special sizes and materials can be customized upon request to meet specific operational needs.
Sinker bars are available in multiple diameter and pin size combinations, ensuring compatibility with different types of sucker rods and polished rods.
| Body Diameter | Pin Size | Thread Type | Material | Special Features |
|---|---|---|---|---|
| 1" (25.4 mm) | 7/8" | Sucker Rod Pin | Carbon Manganese Steel | Cold-formed threads |
| 1 1/8" (28.6 mm) | 1" | Polished Rod Pin | Carbon Manganese Steel | Elevator seat design |
| 1 1/4" (31.8 mm) | 1 1/8" | Sucker Rod Pin | Carbon Manganese Steel | Corrosion-resistant coating |
| 1 1/2" (38.1 mm) | 1 1/4" | Polished Rod Pin | Carbon Manganese Steel | Protective inhibitor lubricant |
| 1 3/4" (44.5 mm) | 1 1/2" | Sucker Rod Pin | Carbon Manganese Steel | Thread protector installed |
Sinker bars provide multiple benefits in oil well operations:
Sinker bars are an integral part of artificial lift systems, helping to maintain proper tension in sucker rod strings. Their ability to add weight ensures smooth and efficient pumping action in the well. By reducing excessive rod bending and minimizing mechanical failures, they enhance the overall efficiency of oil production operations.
Additionally, the sinker bars' robust construction and corrosion-resistant coating make them ideal for use in harsh drilling environments. Whether used in deep wells or high-load applications, these bars play a crucial role in maintaining well integrity and operational efficiency.
To ensure safe transportation and storage, sinker bars are packaged using high-quality materials.
