Product Details
High Drilling Rate HDD Drill Rod Good Flushing Effect For Coal Mining
Specifications:
To guarantee premium quality product, all products material is sourced from Shanghai Baosteel specially developed hot rolling high strength alloy structure tube for oil and gas drilling tools without considering about high cost.
This material uses external refining and vacuum degassing technology with even composition and high purity. The lowest content of harmful chemical elements such as phosphor and sulfur is reached.
Non destructive test is performed according to NDT standard Level 2 with combination of eddy and ultrasonic to guarantee material quality without any defect.
Each of drill pipe is treated by shot peening. After shot peening treatment, surface of drill pipe and thread gets residual pressure stress. This stress can improve drill pipe anti-fatigue service life. Shot peening treatment on thread can help thread compound adhering to thread. Thread service life is improved.
Product Application
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.
