STS: Pipe pipe wuled
STS, a pipe -pipe welded or simply pipeline - a steel product, the main “working advantage” of which should be considered high strength, the ability to withstand the loads in various directions. This and a number of other important properties allows you to actively use technologies using pipeline punts in the work of various types and scale: from the equipment of small pits to the arrangement of deep wells and the construction of large hydraulic facilities.
A separate STS is a pipe equipped with a pair of special castle mounts: fasteners are welded along the pipe and are located “in diameter” against each other.
The round cross section of the profile gives the pipeline to the required “resistance” to the loads (the laws of the sopromat are of great benefit). Groceine locks serve for a sequential connection of individual shpuntin into a pipeline circuit and, as a result, form a protective circuit of the required configuration, which has a given rigidity and tightness. Tightness is especially important when protection against groundwater is necessary, as well as when the construction of a pipe -punt wall is carried out as an alternative to water -reducing measures.
The characteristics of the STS
The main characteristics of the STS are the brand of steel from which the product is produced, as well as its geometric dimensions: length, diameter and wall thickness. Modern computer modeling methods allow you to calculate the strength characteristics of the future pipeline circuit in advance and select the optimal solution depending on the tasks “on the ground”.
The total strength of the structure also depends on the reliability of the locks. Modern castle joints are ready to withstand the loads of up to 700 or more tons of strength per linear meter. At the same time, many Russian companies producing STSs offer both standard structures and their own developments, including patented ones, which are able to provide an even higher reliability of the connection.
The standard diameter of the shopant products varies from 400 to 1600 mm, length up to 12 meters. At the same time, buying products up to 40 meters long is possible to buy “on order”.
The production of the STS is carried out in accordance with GOST 5266, approved in 2010. Only products that are fully consistent with this GOST can be used in Russia.
According to the method of production of STS, they can be available from seamless pipes of hot rental and from direct -haired welded pipes. In the production process, the reliability of fastening of locking joints is carefully monitored. The party can be delivered by a STS of only one size.
A number of companies in Russia produces pipelinePunts on independently developed technical conditions: of course, data from TU cannot be “less strict” than the current GOST.
where the pipe -wrappedis used
The high strength of the Spunteous structures is the main, but not their only advantage.
The tubular form makes it possible to further strengthen the entire structure due to its internal concreting or the ability to place enhancing steel elements inside. Through the cavity of the Spunt, you can “skip” the aircraft of the drilling rig when working on rocky and rocky soils. In addition to “shock” immersion technologies in the ground, methods of pressing and vibro -loading can be used: such methods are relevant, for example, in conditions of dense urban development.
The possibility of repeated use is another advantage of TSHS. After extracting from the soil and the necessary “retraining”, products can be used up to 10 or more times.
The combination of various advantages makes it possible to effectively use a shpunta contours to solve various problems in construction.
- The pipeline pack is optimally suitable for protecting pits and construction sites from shedding soil and the appearance of groundwater. According to the current rules, the fence of the pit is built if its depth exceeds 1.25 meters (in the case of sandy and loose soil).
- Truboshpunt is used to strengthen the coastline, in the construction of hydraulic facilities: berths, docks, gateways. At the same time, the reliability of pipeline discount structures is especially in demand in difficult climatic conditions, for example, in the Far North.
- The construction of supporting walls during the construction of road and railway overpasses and tunnels, protection against soil and rockfall.
- Drilling and wells of wells in the mining industry also requires the creation of reliable protective circuits from the STS.
Trupleshpunt directly from the manufacturer.
It is most profitable to buy the required amount of trumpeter directly from the company engaged in its production.
Given the constantly growing construction needs, the Zagorsky Pipe Plant constantly increases the capacities for the production of various types of STS. Today, an enterprise operating in the territory of the Moscow Region supplies on the market the rogue pipes of its own production with a diameter of 530 to 1420 mm and with a wall thickness of 8 to 35 mm, fully consistent with GOST in force in Russia. Among the regular buyers of the products of the Zagorsky Pipe Plant & NBSP; - Leading Russian corporations, Gazprom, Rosatom, Rosneft, Novatek, FSUE Rosmorport. Cooperation with reliable logistics companies allows the Moscow Regional Metallurgists to ensure uninterrupted supplies of the STS to anywhere in both Russia and in the world.
