HDD drill pipes are used for horizontal directional drilling and rock drilling tools
Describe:
1. After forging the joint material, the density of the material is
increased, the material of the fiber structure is changed, and the
mechanical properties are improved.
2. The joint is treated with nitriding, phosphating or copper to
ensure the anti-corrosion and anti-sticking of the thread and
improve the fatigue resistance of the joint surface.
3. The pipe shrinks and thickens, improves the metallographic
structure, improves the impact toughness, ensures the comprehensive
mechanical properties, and does not damage the friction weld seal.
1. Our drill pipes are of the highest quality and are manufactured
according to strict specifications using advanced processing
technology.
2. It is made of cold-drawn seamless steel pipe, and the material
is in line with international standards.
3. The drill pipe is made of high-quality heat-treated materials to
ensure excellent strength, wear resistance and toughness in the
most demanding applications
4. Drill pipes and casings are manufactured in accordance with
strict industry standards and are tested on site under various
conditions.
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.
