The circulating sub is connected between wellhead pipe string and ground circulating system. When casing is running or finished running, the circulating sub is connected to make fluid circulation. According to the application, the circulating sub is connected between Kelly and casing or between casing and hose. The former is used for fluid circulation during connecting of casing. The later generally is used after connecting of casing. Construction The circulating sub during running casing is equipped with casing pin thread on one end or DP thread and DP box thread or union thread on other end.

The Oil casing is used to support the well bore of oil and gas wells to ensure the normal operation of the whole well after drilling and completion. 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. Therefore, the consumption of casing accounts for more than 70% of all oil well tubes. Casing can be divided into: conduit, surface casing, technical casing and reservoir casing. Specification OD: 4 1/2-20(114.3 - 508 mm) WT: 0.205-0.635(5.21-16.13mm) Length:R1(4.88-7.62m),R2(7.62-10.36m),R3(10.36-14.63m) Application Tubing is used to extract petroleum and natural gas from a well.Casing serves as walls of a well.
