Function and Components:

Function: This component is a type of integral pump-in or side-entry sub. It is used in a drill string or tubing string during well operations (such as cementing, circulation, or well control) to allow fluids to be pumped into the string from the side, rather than through the top connection.
Components:
- Sub (Sub-assembly): A short, heavy-duty pipe section with different connections on each end to adapt various components of a drill string.
- 2-7/8 CS Box x Pin: Refers to the main thread connections on the ends of the sub. One end has a 2-7/8 inch female connection (“Box”), and the other has a 2-7/8 inch male connection (“Pin”). The “CS” likely refers to a specific thread type, possibly “RTS-8 (CS)” or a similar proprietary connection.
- 2″ 1502 Thread Half Side Outlet: A secondary port on the side of the sub with a 2-inch Figure 1502 wing union connection. This union is a high-pressure, quick-connect fitting, suitable for the high working pressures (up to 15,000 psi) typically encountered in oilfield operations.
