Seamless pipes, due to their impressive strength and resistance to various loads, are used in almost all industries. For example, they are in demand in the extraction of minerals, in particular oil and gas, to transport these substances over long distances. Pipes are also used in the design of drilling rigs. In the coal industry, they are used to remove excess steam under pressure. All these options use hot-rolled pipes, which are characterized by high strength. In all areas of mechanical engineering, they are also indispensable. Pipes are used in the construction of aircraft, cars, ships, machine tools, and in the military industry. The main reason for the widespread use of this type of rolled metal is its resistance to internal pressure, unprecedented among analogues. Depending on the purpose, seamless steel pipes are divided into 6 classes: 1 class. Such pipes are designed for laying irrigation systems, electrical lines, as well as transporting gaseous mixtures and various liquids. Also, fences, scaffolding and other similar structures can be assembled from such rolled products. Grade 2 This is rolled products for main pipelines, through which water, oil, gas, solids, fuel and oil products can go. Grade 3 Such pipes are used in environments with high pressure and temperature loads. 4th grade. Products are used in the oil industry as auxiliary elements, parts of drilling and casing structures. Grade 5 This is pipe rolling, which is used as structural elements of masts, towers, cranes or supports. Also, parts of furniture are made from such pipes. 6th grade. Pipes for various branches of engineering. They are used for the manufacture of cylinders, pistons, bearings. They are also used to make tanks for high pressure loads and shaft rings. This division greatly facilitates the choice of pipeline for a particular production. But still, in order to buy seamless pipes, it is better to seek the advice of specialists. In most cases, this will save time. Limitations in the use of seamless steel pipes Another condition for the competent purchase of a batch of pipes is the knowledge of some limits in their use: Pipelines with cold water in apartment buildings. Permissible diameter - up to 150 mm. Hot water supply and heating at industrial facilities and residential buildings. The outer diameter should be between 40 and 50 mm. Main oil and gas pipelines. Pipes with a diameter of 1020 mm or more can be used. Hydraulic systems of cars and road equipment. It all depends on the amount of liquid. The pipe diameter can vary from 8 to 50 mm. Chemical and oil and gas industry. For internal transfer of liquids, pipes up to 273 mm are suitable. In construction, rolling of diameters from 650 mm is suitable for driving the supporting structures of bridges, foundations, piles. The permissible diameter of sewer pipes can vary from 530 to 1020 mm. Products with a diameter of up to 325 mm are used to supply water in urban boiler houses or supply heating to a house. Seamless metal pipe: types, characteristics and applications Despite the active introduction of pipes made of macromolecular compounds, or polymers, into all areas of industry, seamless steel pipes continue to remain popular, and in some areas of human activity they are completely irreplaceable. For example, when assembling water supply circuits in production, only such products are still used. This article is about the types of seamless pipes and their characteristics. Seamless metal pipe: types, characteristics and applications Types of steel pipes It is possible to classify metal pipes - seamless or with a seam - according to many different parameters. For example, according to the method of manufacturing pipes are divided into: spiral-seam electrowelded; longitudinal electric welded; seamless cold deformation; seamless hot-formed pipes. Seamless metal pipe: types, characteristics and applications The wall thickness of products can also vary, respectively, they distinguish: For example, with a diameter of up to 20 mm, a thin-walled pipe is a product with a wall thickness of not more than 1.5 mm. In the case when this parameter does not exceed 0.5 mm, the pipe is called especially thin-walled. The surface of the products can be coated with a corrosion-preventing coating. In most cases, zinc is used for this, although other options are possible, such as chromium plating. Seamless metal pipe: types, characteristics and applications It is possible to apply protective material to all pipes, regardless of the dimensions, wall thickness, geometry and methods by which the products were manufactured. It is obligatory, according to GOST, to apply such a coating to longitudinally welded pipes and products for water and gas pipelines. The procedure for the manufacture of steel pipes In the case of the production of welded pipes, the starting material is steel sheet, which corresponds to
