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.
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.
