Frequently Asked Questions (FAQ):
-
Q: What distinguishes NQ from HQ diamond core barrels?
A: NQ barrels have a smaller diameter (approx. 47.6mm) for finer sampling in shallow holes, while HQ barrels (approx. 63.5mm) are suited for deeper drilling with larger core recovery. -
Q: How long do these barrels typically last under regular use?
A: With proper maintenance, they can endure for hundreds of drilling meters, depending on rock hardness and operational conditions. -
Q: Are these barrels compatible with all types of drilling rigs?
A: Yes, they are designed to fit standard drilling equipment, but compatibility can be confirmed with specific rig models upon request. -
Q: Can I request custom sizes or configurations?
A: Absolutely, we offer customizable options for barrel dimensions and features to meet unique project requirements. -
Q: What maintenance is required to prolong barrel life?
A: Regular cleaning and inspection after use are recommended; avoiding excessive force in hard rock conditions helps maintain performance. -
Q: How do these barrels handle wet drilling environments?
A: They are engineered for both dry and wet drilling, with corrosion-resistant materials ensuring reliability in moist or abrasive settings. -
Q: What is the average delivery time for orders?
A: Standard lead times are 2-4 weeks, but expedited options are available for urgent needs. -
