Can Be Customized Finished Casing
What are the characteristics of the outer thickening oil casing?
The outer thickened oil casing adopts tapered pipe circular thread, which is one of the basic thread buckle types issued by the Petroleum Association after the joint is thickened to complete the connection and sealing. The tooth shape is triangular, dome round bottom, the tooth shape angle is 60 °, the thread taper is 1:16, and the bisector of the tooth shape angle is perpendicular to the axis.

The outer thickened oil casing adopts tapered pipe circular thread, which is one of the basic thread buckle types issued by the Petroleum Association after the joint is thickened to complete the connection and sealing. The tooth shape is triangular, dome round bottom, the tooth shape angle is 60 °, the thread taper is 1:16, and the bisector of the tooth shape angle is perpendicular to the axis. When the thread is tightened, it is sealed by the interference fit of the tooth side of the internal and external thread, which has simple processing, sealing with thread grease, some connection strength, and simple on-site care and application. So what are the characteristics of the outer thickening oil casing? Here we simply understand:
1. The connection strength is strengthened by joint upsetting.
Under the condition of not changing the thread form, the size of the joint is increased by upsetting process, which increases the connection strength and meets the requirements of the lower depth.
2. After matching with thread grease, there is a 0.076mm gap between the tooth top and the tooth bottom of the sealed outer thickened oil casing. When the thread is tightened, the tooth top gap is full of thread grease. After the thread grease is solidified, the leakage channel is congested, thus completing the sealing effect.
External thickening of oil casing in the history of the development of the oil industry has an indelible credit. With the development of the petroleum industry, the geological conditions are becoming increasingly sharp, and the external thickening of the oil casing thread is constantly upgraded, which is gradually suitable for the requirements of unique formations.
The above is the characteristics of the outer thickening of the oil casing, I hope to help you.
