TNGROUP EOOD builds complete pipelines and pipe structures of various types. Performs cutting, clamping, bending of pipes, connection, installation. We work on isometric drawings.
Pipelines and pipe systems
Each pipeline consists of basic elements. These are pipes and their connections, profile parts, fittings and supports, as well as additional elements – measuring devices, remote controls, insulation and others. Usually, pipes are made from metal-steel, cast iron, non-ferrous metals, and for more special purposes – from plastics, concrete, reinforced concrete, ceramics, glass, porcelain, wood and others. In order to install a pipeline of a certain length, the individual pipes must be connected to each other. They are connected by non-threaded sockets, threaded sockets, flanges or by welding. Our base has straight-seam, seamless, spiral-welded pipes in stock.
Peculiarities in installation and operation of pipelines and fittings
The volume of work on the installation of technological pipelines compared to the total volume of installation work in chemical industries reaches 35 ÷ 40%, and in the oil refining industry up to 55 ÷ 60%.
When centering the welding pipes, special devices are used, ensuring the necessary accuracy.
Their cleaning can be continued by washing with alcohol or gasoline with hot water and cleaning solutions.
During the installation of the pipelines, after their placement along the route, leveling is carried out in the horizontal and vertical direction of individual segments (parts) over a certain distance. Movable and fixed supports, fittings, temperature compensators and others are placed. When installing inter-shop pipelines, it is possible to use lifting machines, cranes, etc. When installing pipelines inside the workshops, it is necessary to ensure access to all elements of the pipeline fittings. Pipelines are most often installed as assembled units, representing a section of the pipeline with fittings, compensators and thermal insulation. In recent years, the block equipment method (block assembly technology) has been used a lot. In this method, several units of equipment together with pipelines, fittings, control and management devices arrive at the installation site in a ready form from the manufacturing company. The blocks are installed in a certain order of assembly. This increases the speed of installation and its reliability. After the completion of the installation works, hydraulic or pneumatic tests of the pipelines are carried out in order to check the tightness and strength of the construction.
