The oil refining industry is a very important element of any state's industry, so the manufacture of such products is constantly being improved and strictly controlled by regulatory documentation.

One of the brightest examples of such control is the production of drill pipes. Because the technology of deep drilling implies using only high-quality and reliable units and auxiliary elements that are extremely durable and strong and show high resistance to destruction of corrosive nature. Since drill pipes are used for drilling rather deep wells in both oil and gas fields, they are constantly exposed to the negative influence of aggressive environment, at great depths. This means that the production of such products implies special attention to increased resistance of the material. A wide range of size range allows you to choose the necessary diameter and wall thickness of the pipe, depending on the operating conditions and climatic zone.

Varieties

There are several varieties of pipes of similar purpose. Each of them has its own field of application. For example a weighted and well-balanced drill pipe creates an axial load in the area of bit and, thus, gives additional rigidity to the entire drill string. And casing pipe is used in the construction of a well and the arrangement of the entire oil or gas field. Sometimes the different layers of oil or gas are separated from each other with such products, and sometimes the wall or wellhead of a drill hole is reinforced.

Manufacturing

Even at the production stage, drill pipes are coated with a reliable protective coating, of a conservation nature with high anti-corrosion properties. The threaded joints should be lubricated with the same grease in order to prevent the premature failure of the entire structure. Also at the junction of multiple elements of the design is supposed to use caps and nipples safety properties.

Rolling mills of a screw or press and roll type are used for production. These lines by means of numerous manipulations sew the semi-finished product into a hollow sleeve. This type of equipment makes it possible to produce the desired thermowell size in a single process step. Then the finished sleeve is transformed into a draft tube with a given wall thickness and required diameter. Afterwards the product is supposed to be calibrated, cooled, trimmed and tested.

Operation

Drill pipes are indispensable when drilling very deep wells, thanks to their exceptional performance qualities. Materials of the highest quality are used in their manufacture. Today, such products made of polyvinyl chloride are quite popular. Such material compares favorably with its metal counterpart with high corrosion resistance and reliability. Service life of more than fifty years, good resistance to chemical aggression and environmental safety of this product noticeably expanded its use not only in the oil industry, but also in many other sectors of the economy.
