Application:coupling is a short pipe used to connect two pipes. Because of its convenient use, 

hoop is widely used in civil construction, industry, agriculture and other fields.

The tubing used to make the coupling is called the tubing coupling material. Each well should use 

several layers of casing according to different drilling depth and geological conditions. Cement 

cementing is used after casing goes down. It is different from tubing and drill pipe. It can not be

 reused. It belongs to disposable consumable material.
