Technical Specifications
Overview
High-Performance DTH Drill Pipe
These friction-welded DTH (Down-The-Hole) drill pipes are engineered for demanding rock drilling and piling applications in mining and construction industries. Manufactured using high-quality carbon steel, each rod undergoes rigorous testing including spectrograph analysis, impact, and tension tests to ensure structural integrity. Advanced features such as anti-adhesion threads with nitrogen treatment and integral heat treatment provide superior durability, minimal energy loss, and extended service life in high-pressure environments.
