Core Barrel Spare Parts

PEERCHEER offers BQ NQ HQ PQ NQ3 HQ3 PQ3 BWL NWL HWL PWL landing ring for use with BQ NQ HQ PQ core barrels. The landing ring sits in the upper-end of the outer tube and is retained by the mating coupling. As the inner tube assembly trips into the drill string, the landing shoulder on the Head Assembly impacts the landing ring setting the inner tube assembly into drilling position.Q series landing rings are available for application in standard DCDMA B N H P size.
PEERCHEER'S landing rings are made made of high quality alloy steel that is specially heat treated for improved impact toughness and durability.

PEERCHEER offers BQ NQ HQ PQ BWL NWL HWL PWL core lifter for use with BQ NQ HQ PQ core barrels. The BQ NQ HQ PQ core lifter is a hardened steel, split collar with a tapered body that mates to a tapered socket in the BQ NQ HQ PQ core lifter case. In a core breaking operation, the drill string is lifted off bottom and the core sample begins to slide out of the inner-tube. Grip features on the inner surface of the core lifter catch the moving core sample and pull the core lifter towards the smaller end of the tapered socket in the core lifter case. The core lifter is constricted against the core sample and retains it after it has broken, allowing retrieval to surface. Q series core lifters are available for application in standard DCDMA B N H P size.
PEERCHEER'S core lifters are made out of high-quality alloy steel that has been heat treated to increase strength, toughness, and wear life.

PEERCHEER offers BQ NQ HQ PQ BWL NWL HWL PWL core lifter case for use with BQ NQ HQ PQ core barrels. The BQ NQ HQ PQ core lifter case mates to the inner-tube and houses the core lifter in a tapered socket which controls movement of the BQ NQ HQ PQ core lifter. As the drill string is lifted during a core breaking operation, the core lifter case bottoms out on the inside of the drill bit transferring the pullback load from the drill string to the core lifter until the core sample breaks. Q series core lifter cases are available for application in standard DCDMA B N H P size.
PEERCHEER’S core lifters are made of a high-quality alloy steel that is specially heat treated to increase strength,toughness, and wear life.

PEERCHEER offers BQ NQ HQ PQ NQ3 HQ3 PQ3 BWL NWL HWL PWL NWL-3 HWL-3 PWL-3 inner tube stabilizer for use with BQ NQ HQ PQ core barrels. The BQ NQ HQ PQ inner tube stabilizer is seated in the reaming shell , the replaceable and reversible BQ NQ HQ PQ inner tube stabilizer provides centralizing for improved sample recovery and a bearing between the stationary inner tube and the rotating outer tube. Inner tube stabilizers are available for application in standard DCDMA B N H P size.
PEERCHEER'S inner tube stabilizers are made of high quality bronze alloy. The purpose of the inner tube stabilizer is to stabilize the inner tube at the bottom of the hole, directly above the bit or near the core lifter case.

PEERCHEER offers BQ NQ HQ PQ NQ3 HQ3 PQ3 NWL HWL PWL locking couplings for use with BQ NQ HQ PQ core barrels. BQ NQ HQ PQ locking coupling connects the drill string to the outer-tube assembly and provides a mating surface which the head assembly latches ride against while drilling. BQ NQ HQ PQ locking couplings provide directional control for BQ NQ HQ PQ core barrel assembly through wear resistant stabilizing pads that wear down against the drill hole wall.Q series Locking couplings are available for application in standard DCDMA B N H P size.
PEERCHEER'S locking couplings are made out of high quality alloy steel with a hard-faced latch resting area for better latching reliability.
PEERCHEER offers the option of a TANG which is the tab of steel located on the pin end of the locking coupling.
