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 tubes are designed to withstand high torque while retaining a large inner diameter to achieve excellent drilling fluid flow so that the threads will not deform.
Optimal design
Through the evenly distributed drill rod strength and stress optimization design, the potential of the drill bit can be fully utilized.
Forged connector
The connector material is forged, has improved material density, and changes the fiber texture of the material, so that the general mechanical properties of the material have been greatly improved. 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.
Application
It has applied successfully in gas exploration, drilling, geothermal well drilling and mine rescue hole and a ventilation hole construction, etc.
Quality control
The complete systematic testing equipment guarantees BaiWei first-class products quality with attitude of rigorous speciality and the spirit of aggressive research and self probing.
