Forging Remet Metzke Thread 3 1/2" 4" Well Drilling Pipe
Well Drilling Pipe Introduction
Each drill pipe consists of three parts welded together, a central portion and two end pieces. The end piece contains either a male ("pin") or a female ("box") thread, which permits interconnection of two drill pipes. The entire drill string is subjected to extremely high loads during drilling, and the thread is always the most critical part in each pipe. If for any reason the male and female thread do not fit exactly into each other, the thread will most probably break and you will lose your entire drill string.
