China Short Drill Collar Manufacturing
Diameter: The outside diameter of a Short Drill Collar is 3 1/2, 4 1/2, and 5 inches. The inside diameter can also vary but is usually much smaller than the outside diameter.
Length: As the name suggests, Short Drill Collars are shorter than regular drill collars. They can range in length from 5 to 10 feet, depending on the application.
Material: Short Drill Collars are made of high-strength alloy steel, designed to withstand the intense pressures and stresses of drilling operations.
Connections: Short Drill Collars usually have API connections, which allow them to be screwed into the drill string.
Weight: The weight of a Short Drill Collar can vary greatly depending on its size and material, but it is generally heavy enough to provide significant weight on the drill bit.
Slip and elevator recesses: These are grooves cut into the collar to allow for secure gripping by the handling tools.

Safety joint for oil well drilling fishing tools
Quickly releases from a downhole string should the assembly below the safety joint become stuck
Enables the recovery of tools and down-hole gauges above the safety joint when the string is stuck
Allows the retrieval of the lower (stuck)portion by either fishing over the OD of the box section or by re-engaging the pin section into the box section
Prevents right-hand torque from acting on the shear pin
Easily disengages and reengages with a large, coarse thread design that carries the string load
