To create an additional axial load on the nature of the bit in the drill setting applies drill collar. The use of such a structural element greatly facilitates the production of oil or gas. Varied performance of these products is able to cover almost all the main points of the drilling process. Balanced pipe attached to the entire range of equipment for stiffness, thick-walled product, transferring torque from the rotor to the tool facilitates the movement in a layer of rock while the horizontal well development. And in telemetry systems and inclinometers have found the use of the product of a balanced non-magnetic character. When drilling a large enough depth justified the use of weighted pipes with special grooves that facilitate waste rock generated.
Industrial facilities that manufacture such products include the entire production cycle, from plants and steel forging and thermal complexes, finishing machining lines. The material for these pipes are steel increased strength category under the brand name «D» or «R». A wide range of standard sizes, regulated by normative documentation provides a complete standardization and interchangeability of such products.
Each type of drill pipe is measured repeatedly during manufacture and subjected to ultrasonic flaw detection in the thickness of latent defects of the workpiece material. To increase the strength characteristics of a threaded connection similar product is calendered at low temperatures to the top of the pressure increasing and decreasing radius susceptibility to cracking during operation.
Best Performance of the pipe due to the use for its manufacturing of alloy structural steel, particularly resistant to wear and tear with regular heavy loads. Heat treatment improves the initial mechanical properties of the material and reduces the impact on the surface of the tube shocks. Additional processing weighted drill pipe, such as copper plating or surface coating treatment it phosphor can improve the durability of the threaded connection and the drilling tool to protect the threads from sticking to the base during operation.
These products are in great demand not only in the production of important industrial resources. Sometimes these products are successfully used in the course of exploration work. The special design tool joints and a thickening at the ends of these tubes enables a reliable connection of all elements of the production complex and long-term service of all drilling equipment. On the length of eight millimeters from the edge of the article uses a special heat treatment to give special strength and hardness of the castle structures.
We supply a wide range of drill pipe at the best price. The technical documentation included data on the performance of the product. We easily purchase wholesale products for any large-scale productions. We provide services to retail customers. High level of service, compliance with GOST and international standards of quality, service efficiency are the face of our company.
