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.

China Short Drill Pipe Manufacturing
Length: Lengths ranging from 5 feet to 10 feet.
Outside Diameter (OD): The OD of short drill pipes usually varies between 2 3/8 inches to 6 5/8 inches.
Wall Thickness: The wall thickness of these pipes can vary greatly depending on the pipe material and the expected downhole conditions.
Material: Short drill pipes are made from high-strength steel or alloy materials that can withstand the harsh drilling environment.
Tool Joint: The drill pipes typically have tool joints on both ends. These tool joints can be of different types such as NC (Numeric Connection), IF (Internal Flush), or FH (Full Hole).
