Technological racks

Technological overpasses are a structure consisting of a foundation, supports and spans (in some cases they may be absent) and used to fix pipelines on the ground at the required height above the ground.
Technological overpasses are used in cases where underground communications are impossible or impractical. The use of such structures significantly reduces the cost of installing pipelines, and also facilitates their maintenance due to the availability of free access. The installation of such metal structures allows you to optimize the costs required for the maintenance of the facility where they are used. In addition, the systems are equipped with additional elements that ensure the safety of the operating personnel.

Such designs are versatile and in some cases can also be used to fix cables, including power ones. In this case, additional cable protection is required, which is usually carried out by means of special steel boxes.

There are standard projects for overpasses for technological pipelines. However, if it is necessary to solve specific problems, such structures can be made on the basis of a special project.

The design of technological racks usually does not imply the presence of spans when it comes to the installation of a large diameter pipeline.

Overpasses of technological pipelines can have several tiers. The maximum number of tiers for such structures is three. The calculation of the parameters of a metal structure, the number of nodes and tiers is carried out in accordance with the characteristics of the site on which it will be used, the load that it will have to experience, as well as climatic conditions that can have an additional temporary or short-term impact.

For the arrangement of overpasses for technological pipelines, several types of supports are used: anchor, intermediate, single-column and two-column. Anchor supports are the most stable structures designed for high horizontal forces. As a rule, they are used at those points of overpasses that have the maximum load.

Since technological overpasses are operated outdoors, they are designed for high wind loads and temperature fluctuations, and also have high-quality anti-corrosion protection, ensuring their service life for 35-30 years. To ensure such protection, hot-dip galvanizing, a modern and efficient technology, can be used, which involves processing metal structures and system elements at temperatures at which zinc melts. In this state, zinc acquires the ability to penetrate into the deep layers of steel and form a connection with it, strong and at the same time aesthetic. The advantage of this technology over all others is that the resulting coating is characterized by maximum durability and, accordingly, prolongs the service life of the metal structures themselves, which most often lose their properties precisely due to the destructive effects of corrosion.
