The characteristics of "BAIWEI" drill rods

Two force regions

The thread of the non-digging drill pipe produced by the company has two Force areas. This structure is designed to reduce the resistance faced by drill A during the construction process. These pipes are designed to withstand high torque while retaining a large inner diameter for excellent drilling fluid flow, so that the threads will not deform.

Optimal design

Drill rods through the dispersion of equal strength And stress optimal design, can give full play to the Potential of drill material.

Forged connector

The connector material is forged, has an improved material density, and changes the fiber texture of the material, thereby greatly improving the general mechanical properties of the material. The end ensures that the thread is anti-corrosion, anti-sticking, and improves the fatigue resistance of the joint surface.

Upsetting & thicking

The setting thickness and thickening of the bar have been improved. The metallurgical structure and enhanced impact toughness ensure that the comprehensive mechanical properties and friction welding seal are not damaged.
