What Are Wireline Stop Rings?
Wireline stop rings are small but essential components used in core drilling systems. They are typically made of high-quality alloy steel and undergo special heat treatment to enhance their strength, toughness, and wear resistance1. These rings are designed to work in conjunction with core lifters and core barrels.
Function and Importance
The primary function of wireline stop rings is to prevent the core lifter from moving upward when retrieving core samples. As the core sample enters the inner tube, the stop ring ensures that the core lifter remains in place. Without this mechanism, the core lifter could dislodge, compromising the integrity of the sample.
Design and Application
Material: High-quality alloy steel
Heat Treatment: Specially treated for durability
Compatibility: Available for various core barrel sizes (e.g., NQ3, HQ3, PQ3)
Installation: Seats into a mating groove within the core lifter case
Conclusion
Wireline stop rings may be small, but their impact on core drilling accuracy and sample quality is significant. By preventing core lifter movement, they ensure reliable data collection during exploration and mining activities.
