HIGH TORQUE THREADED CONNECTIONS WITH EXTERNAL UPSET AND MULTIPLE SEALS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240052710 titled 'HIGH TORQUE THREADED CONNECTIONS WITH EXTERNAL UPSET AND MULTIPLE SEALS
Simplified Explanation
- A threaded connection consists of a first tubular member with an internal thread profile and a second tubular member with an external thread profile that can engage with the internal thread profile.
- The external thread profile has a first section at a first taper angle, a second section at a second taper angle, and an intermediate shoulder between the two sections that matches with a corresponding shoulder on the internal thread profile.
- The cross-sectional area of the pin end increases at the intermediate shoulder, providing stability and strength to the connection.
Potential Applications
- Oil and gas industry for connecting drill pipes and casings.
- Automotive industry for connecting various components in vehicles.
- Construction industry for joining structural elements.
Problems Solved
- Provides a secure and stable connection between two tubular members.
- Prevents loosening or disconnection due to vibrations or external forces.
- Ensures proper alignment and engagement of the threads.
Benefits
- Increased strength and stability of the connection.
- Reduced risk of leaks or failures.
- Easy and efficient assembly and disassembly of components.
Original Abstract Submitted
a threaded connection includes a first tubular member having a box end defining an internal thread profile, and a second tubular member having a pin end defining an external thread profile threadably engageable with the internal thread profile of the box end. the external thread profile includes a first section that extends at a first taper angle relative to a longitudinal axis of the threaded connection, a second section extending from the first section at a second taper angle relative to the longitudinal axis, and an intermediate shoulder provided at a transition between the first and second sections and engageable with a corresponding intermediate shoulder provided on the internal thread profile. a cross-sectional area of the pin end increases at the intermediate shoulder.
