Alloy Structure Steels HDD Drill Pipe For Underground Utilities Installation
Description of Horizontal Directional Drilling HDD Drill pipe For
Installation Of Underground Utilities
HDD drill pipe is a tool applicable for transferring torque and
tension of drillers in the process of directional drilling
construction. Due to the fact that it has to bear torsion, tension,
bending, friction and vibration in the process of directional
construction, the requirements for processing process are very
strict.
The raw materials selected by our company are all the alloy
structure steels for geographical usage produced by Baogang Steel.
After laboratory tests, both ends of a pipe are upsetted and
proceeded to overall heat treatment, then friction welded. Before
finished drill pipes are plated and packaged, a series of tests
have to be implemented including hardness, metallurgical structure,
physical performances, etc.
