50-9.625-40.0-BTC-P REV H is a standardized part number specification for an oilfield downhole casing torque ring.
Here is the breakdown of what each segment in this industrial specification represents:
- 50: Typically designates the yield strength, material grade classification, or specific model series.
- 9.625: Specifies the outer diameter (OD) of the oilwell casing, which is 9-5/8 inches.
- 40.0: Represents the linear weight of the casing pipe, measured in 40.0 pounds per foot (lb/ft).
- BTC: Indicates the connection thread type, standing for Buttress Thread Casing.
- P: Usually stands for Premiere Inc. (the primary manufacturer/patent holder of these specific torque rings).
- REV H: Denotes Revision H, meaning this is the 8th engineering design iteration or manufacturing update for the component.
What is this used for?
These rings are inserted into the standard Buttress threaded coupling connections of a 9-5/8" casing string. They create a positive torque shoulder inside the connection. This allows the casing pipe to withstand significantly higher torsional forces during rotation without over-threading or damaging the joint, which is crucial for directional drilling or when navigating obstructions downhole.
