The development of petroleum industry involves the use of special equipment and pipes with high requirements for quality and performance. After all, the oil pipes used for laying pipelines, drilling wells and pumping an important industrial fuel work in difficult conditions under constant exposure not only aggressive media, but also the harsh weather and climatic conditions.
Production of oil pipe involves the use of high-quality steel, resistant to corrosion damage. Depending on the purpose of a particular type of pipes, semi-finished products can be subjected to additional heat treatment, hardening additives or special application for finished products protective coatings can extend the service life of pipes and their resistance to destruction.
The size range of similar products is presented in a rather wide range (from one hundred fourteen to five hundred thirty millimeters in diameter) and regulated by normative documents. Moreover, state standards for such products stipulate not only the pipe diameters, but the thickness of their walls.
Pipe oil use enough critical parts, so their production requires special attention as to the quality of sheet metal intended for such products, and the strict observance of technological process. Preferably used for oil industry products produced by hot deformation method, without welds. The production technology assumes control not only the overall condition of the semi-finished product, but also its structure at macro — and microscopic level. Then measuring the workpiece on the measuring cut length. Next, after a preliminary designation of the center of the prefabricated part is heated in a special oven (3-Sonny unit with walking hearth furnace). The product was then stitched into a hollow structural shell and is rolled into a rough version of the finished pipe. The finished pipe is calibrated and reduced, then controlled by its main characteristics — the diameter and wall thickness.
Such tubes are used not only in laying gas or oil pipelines, but also suitable for the installation of household water supply. The main advantage of this product is its high corrosion resistance and durability due to an exclusive production technology and use quality material durable steels alloyed chemical elements.
During operation these products require constant monitoring of the surface condition. It involved a variety of laboratory tests from ultrasonic testing to the metallographic analysis of defective parts. The key performance characteristics of oil pipes are constantly improved by regular review of regulatory documents and optimization of the production technology. Due to this fact increases the durability and longevity of pipe products.
