China's first one-time process treatment technology for integral drill pipe intermediate frequency heat treatment production line
The joint adopts high-strength medium sandblasting technology combined with laser treatment technology, and the hard layer is 0.1-0.3mm
The surface hardness, hard layer and uniform distribution of the two connecting ends are durable and wear-resistant, stable and reliable, and the service life of the drill pipe is improved.
working principle:
The trenchless steerable drilling pipe laying method is a construction technology for laying, repairing and replacing underground pipelines without digging trenches on the surface by using technical means such as cliff soil drilling tools and pipeline detection. It uses a drilling rig placed on the surface to form holes by water jet or extrusion, and receives signals from the drill bit on the surface to control the drilling trajectory. The construction process is divided into: drilling pilot holes, reaming, pipelines Back to drag three stages.
Scope of use:
It is suitable for horizontal drilling of drill pipe in various complex formations.
It is suitable for drilling with different specifications and models of drill pipes for different laying pipe diameters and weights.
It is suitable for the requirements of top thrust and return drag force of ground drilling rigs. Different specifications and models of drill pipes are selected for drilling.

Advantage
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.
