Characteristics of HDD Drill Pipe (Forged Type)

The thread of the trenchless drill pipe has two force-bearing regions to reduce the resistance during construction. Particularly offered for high torque, the drill rod is designed with large inner diameter for the drilling fluid to avoid thread deform.

1. Force-bearing shoulder A
2. Force-bearing shoulder B
