The characteristics of "BAIWEI" drill rods

Two force regions

The threads of the non-dig drill pipe produced in the company have two Force regions. Such structure is designed to reduce the resistance that A drill faces during the construction process. The pipes are designed to handle high torque while retaining a large inside Diameter for superior 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

Connector material had been forged, that have Improved material density, changed the fibrous Texture of the material, so that the general mechanical Properties of the material have been more improved Nitride, phosphide or copper plating processing Nitride, phosphide or copper plate processing to the rod ends Have ensured thread anti-corrosion, anti-bonding, and improved Joint surface fatigue resistance.

Upsetting & thicking

Upsetting & thicking to the rods have improved The metallurgical structure and enhanced the Impact toughness, that have ensured comprehensive Mechanical properties and the friction weld seals Not be broken.
