Diameter 300-1200mm Long Spiral Rock Drill Rods High Elasticity Listed

Diameter 300-1200mm long spiral for core mining water well drilling rod

Core drilling rod introduction

This drilling rod adopts the new T-shaped steel strip with pre-stress winding, which has the characteristics

of light weight and high elasticity, and is not easy to bend. It has automatic self-aligning function and stable

operation. The drill rod is connected by a spring pin, which is automatically locked and disassembled more

conveniently and quickly. It can be used with hand-held pneumatic drills or reinforced coal drills. It can be

drilled for 8-30 meters, which is especially suitable for high-density water exploration and discharge gas

drilling in mines.

Drill rod specifications

Characteristics

1. It adopts plug-in threaded connection, which is convenient and quick to disassemble, good in sealing,

high in tensile strength and high in pile quality. Good verticality for easy disassembly and installation.
2. This product adopts A3, 4mm thick coiled plate, ribbed joint adopts 35# cast steel piece, and pipe

joint is welded on both sides.
3. This product is tested by water and gas mixed test before leaving the factory.

The following are the relevant operation steps for adding drill rods to water well drilling machines:

Operation of Adding Drill Pipe to Water Well Drilling Machine

1. When drilling to a depth of one drill rod and additional drill rods are required, stop advancing first, then stop rotating, and turn off the cooling water;
2. Manipulate the gripper handle to clamp the drill rod and open the micro regulating flow valve (right rotation);
3. The rotator rotates in reverse, and at the same time, the feed cylinder retracts to separate the water braid shaft from the drill rod;
4. Stop rotating and operate the quick advance and retreat handle to the quick retreat position to quickly retract the chuck into place;
5. Connect the drill rod to be connected to the previous one, and the rotator moves forward while rotating. When the trapezoidal taper thread of the water braid shaft comes into contact with the taper thread of the newly connected drill rod, immediately operate the gripper handle, release the gripper, and complete the drill rod connection.
