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.
