Horizontal directional drill pipe S135 steel grade, 73mm*3000mm
Describe:
HDD drill pipe is a tool suitable for transmitting driller torque
and tension during directional drilling construction. Due to the
torsion, tension, bending, friction and vibration in the
directional construction process, the requirements on the
processing technology are very strict.
1. Use American MTI equipment for friction welding, computer
automatic control, heat treatment, grinding, and magnetic particle
testing to ensure the high quality of the finished product.
2. Processing can be provided according to customer requirements.
The finished product is hard-bent, with high hardness and no
cracking.
3. The tool joints are processed by a 1500T precision forging press
to ensure the quality of the joints and have high compactness,
cleanliness, wear resistance, and excellent mechanical properties
of homogeneity.
Quality Control
Quality guarantee is not only responsible for customers, but also
the assurance of enterprise's steady development. The necessary
test equipment and the effective & perfect production process
control is the assurance of product quality. Taking the spirit of
"To win the market with innovation, to serve the customers with
friendship, to build the brand with quality, to develop the
enterprise with sincerity", we utilize the advanced testing methods
to make each product meticulously.
The raw materials selected by our company are all the alloy
structure steels for geographical usage produced by Baogang Steel.
After laboratory tests, 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.
