Introduction of Oil drilling Universal elbow
An oil drilling universal elbow, also known as a drilling swivel, is a crucial component in the drilling rig system used in the oil and gas industry. It is located between the kelly and the drill pipe, providing a rotating connection that allows the drill string to rotate while drilling a well.

The drilling universal elbow or swivel is designed to handle high pressures and torque generated during the drilling process. It provides a pathway for drilling mud to be pumped down the drill string while simultaneously allowing the rotation of the drill bit. This is essential for drilling operations as it helps in maintaining stability and control of the wellbore.

The swivel typically consists of a housing, a gooseneck, bearings, seals, and a rotating stem. The housing contains internal passages for mud flow, while the gooseneck allows for articulation of the drill string. Bearings and seals facilitate smooth rotation while preventing leakage of drilling mud. The rotating stem connects the swivel to the kelly and allows the transmission of torque to the drill string.

YITAI Oil drilling Universal elbow Feature And Application
Features:

Rotating Connection: The primary feature of a drilling universal elbow is its ability to provide a rotating connection between the kelly and the drill pipe. It allows the drill string to rotate while drilling a well, enabling effective drilling operations.

High Pressure and Torque Handling: Oil drilling universal elbows are designed to withstand high pressures and torque associated with drilling operations. They can handle the intense forces generated during drilling, ensuring reliable performance in demanding drilling conditions.

Mud Flow Pathway: The swivel incorporates internal passages for the flow of drilling mud. It allows the mud to be pumped down the drill string while the drill string is rotating. This continuous flow of drilling mud helps in cooling and lubricating the drill bit, removing drill cuttings, and maintaining stability in the wellbore.

Articulation: The drilling swivel often includes a gooseneck design, allowing for articulation or flexion of the drill string. This feature helps accommodate deviations or changes in the wellbore path and allows for better control during drilling operations.

Applications:

Drilling Rigs: Oil drilling universal elbows are a critical component of drilling rigs used in the oil and gas industry. They are installed between the kelly and the drill pipe in a drill string, facilitating the rotation of the drill bit during the drilling process.

Well Drilling: The primary application of an oil drilling universal elbow is in the drilling of oil or gas wells. It helps in the penetration of the rock formations, facilitates the circulation of drilling mud, and allows for the extraction of valuable hydrocarbons.
