How to choose a geological drill pipe

Usually, when purchasing engineering equipment, the first thing that comes to mind is whether the model, specifications, and parameters meet the requirements. The selection of geological drill pipes is nothing more than these.

1. Standard structure of geological drill pipe:

A geological drill pipe is a drilling tool that uses alloy steel pipe to be thickened by upsetting at both ends, turns small pitch taper threads, and connects with lock joints. It is used in the field of geological exploration, transmits Drilling Rig torque to the bottom hole bit, and is responsible for the transmission of drilling fluid. Drill rods are divided into 1 meter, 2 meters, 3 meters, and 4 meters in length, and customers can choose according to the depth of the drilling. Drill rods can be divided into 40, 50, 60, and 89 drill rods according to their size. The 50 drill rod has a wider application range and is more practical for drilling soil, rock and sand.

2. Technical parameters of geological drill pipe:

3. Common specifications and materials of geological drill pipes:

Generally, there are several large specifications such as Ф42x760, Ф42x800, Ф42x1000, Ф42x1500, Ф42x2000, Ф42x2500, Ф50x800, Ф50x1000, Ф50x1500, Ф50x2000, Ф50x3000, Ф63.5X1000, Ф63.5X1500, Ф73 X1000, Ф73 X1500. The drill pipe of our company's model specification of R780 (42MnMo7) adopts the normalizing + tempering heat treatment process, which has excellent mechanical properties and is suitable for higher-level drilling requirements. You can also ask the manufacturer to tailor it according to your own needs.
