Product Parameters

 

Introduction

A drill pipe is a seamless steel pipe that composes around 95% of the length of a drill string. For clarity, a drill string is what is used to actually drill into the ground to extract resources. The drill pipe is hollow, which allows drilling fluid to flow freely throughout the pipe and the pumping process to be completed successfully.
