Build steel pipes, people learned long ago. However, in recent decades due to the rapid growth of the use of energy and raw materials as oil and gas, construction of steel pipelines was the most important sector of the economy. Modern steel pipe is a complex technical structure, consisting of a line of welded pipes, supporting structures, fittings (valves, gate valves, cocks, valves) instrumentation and other components – the elements of the pipeline (transitions, elbows, caps, joints). There are two kinds of steel pipes – internal and backbone. Pipelines are used for internal transportation of different products within a facility, enterprise, residential area.

Such pipelines are literally all around us in everyday life, they become habitual and therefore invisible. By the main steel piping product (water, oil, gas) is passed from the place of production to point of consumption. Their length is several thousand kilometers. Of these pipelines, and will continue it. First of all, the structure of the field pipeline (PMTP). It consists of a so-called head works in which the product is prepared for shipping, the actual steel pipeline, compressor and pump stations, storage facilities and product distribution centers, support facilities (repair and maintenance services, communication systems, power lines, office and household objects).

The main component of the main field Pipeline (PMTP) – the linear part, collected from the pipes fittings. K line facilities also include pipeline crossing various obstacles, supporting structures and various support facilities, along the route. After the planned route of steel pipe, starting to clean up and planning of the band, setting up the technical and consumer base. Next, take the incoming pipeline elements (pipes) weld them into sections of three or four tubes and take out the section, and other materials on the road. Pipe sections are welded into a single thread, dig a trench and isolate the steel pipe is laid and covered trench. Then clean the inside cavity pipeline and experience it for strength. After successful tests steel pipe sit-up.
