In the development process of petroleum industry, petroleum pipelines and petroleum pipe threads play an indispensable role. Different oil pipelines correspond to different pipe threads. The threads used for petroleum pipes are mainly divided into two categories: the joint threads of petroleum drilling tools used for the connection of downhole tools and drill string components and the joint threads of oil and Casing pipes used for the connection of oil and CASING pipes.
With the development of oil and gas drilling and production in the direction of deeper, higher pressure, higher temperature and other more severe working conditions, as well as the continuous progress of petroleum drilling and production technology, conventional petroleum pipe threads are difficult to meet the development needs of oil fields, thus promoting the development and research of special threaded joints. Petroleum pipe threads are moving towards special threads with better strength and sealing performance.

Casing is a large-diameter pipe that serves as the structural retainer for the walls of oil and gas wells or wellbore.

It is inserted into a well bore and cemented in place to protect both subsurface formations and the wellbore from collapsing and to allow

drilling fluid to circulate and extraction to take place
