In order to create additional axial load on a drill bit a weighted drill pipe is used in a drilling rig. The use of such a structural element greatly facilitates oil or gas production. A variety of design of such products is able to cover almost all the main moments of the drilling process. Balanced pipes give additional rigidity to the whole complex of equipment, the thick-walled product, transmitting torque from the rotor to the tool, facilitates movement in a rock layer during development of a horizontal well. And in telemetry systems and inclinometers balanced nonmagnetic products have found their application. When drilling wells with sufficient depth it is reasonable to use weighted pipes with special grooves that facilitate waste of excavated rock.

Manufacturing

Production complexes that produce such products include the whole technological cycle, beginning with steelmaking shops and forging-thermal complexes, and ending with mechanical processing lines. The material for these pipes is high-strength steel of "D" or "K" grade. Wide range of standard sizes regulated by normative documentation ensures complete standardization and interchangeability of such products.

Each drill pipe of this type is measured during manufacture and subjected to ultrasonic defectoscopy in order to detect flaws hidden inside the material thickness of the billet. To increase the strength characteristics of the threaded joint, such a product is calendered at low temperatures to increase the pressure of the upper part of the radius and reduce the tendency to cracking during operation.

Additional Processing

The high performance of this pipe is due to the use of alloyed structural steel for its manufacture, which is particularly resistant to wear and tear under regular high loads. Heat treatment improves initial mechanical characteristics of the material and reduces the influence of shock loads on the tubing surface. Additional processing of drill pipe weighted pipe, such as copper plating or phosphorus coating, can increase the durability of a threaded joint and protect the drill pipe from sticking to the thread base during operation.

Application of

These products are not only in high demand in the extraction of important industrial resources. Sometimes such products are successfully used in the course of geological prospecting works. A special design of interlocking joints and some thickening at the ends of such pipes provides a reliable connection of all elements of the mining complex and long life of all drilling equipment. On a length of eight hundred millimeters from the edge of the product a special heat treatment is used to impart special strength and hardness to the locking structures.
