Steel pipes: types and features
In the modern market, rolled steel pipe is traditionally considered one of the most common types of production. It is difficult to imagine modern construction without the use of this element. It is presented in a large assortment, it may have some unique features. In order to choose the optimal type of steel pipes in the required quantity, it is advisable to consult competent specialists. We will help you understand the subtleties and make an order for specific requests. The price is always guaranteed to be the most favorable for each individual client, and the service will surprise even the most demanding people.
Classification and its differences
The metal structure can have different shapes and sizes and is made using different technologies. In accordance with such nuances, classification takes place. The most popular type of classification is the method of production. Here it is possible to distinguish welded products and rolled products. In the latter case, the method of cold or hot rolling can be used. In such a situation, a hole remains in the central part of the product, which can be round or square. By observing the technology, it is possible to achieve a high level of wear resistance, which expands the scope of application.
Pipes can be straight-seam and spiral-seam. In the first variant, the steel is heated, after which the folding process takes place with the preservation of the seam along the entire length. In the second, the winding takes place in a spiral, and at the final stage of production, the edges are welded.
Scope of application
It is quite extensive due to the variety of execution options. Profile pipes are actively used in the following industries:
- Production of furniture.
- Mechanical engineering
- Light industry.
- Agriculture.
There are also pipes for arranging various systems, for example, gas pipes or water pipes.
Technical characteristics
Steel pipes can differ in various technical parameters. Among the most common can be noted:
- Size Length and diameter are the main parameters. They have a direct impact on the price.
- Section geometry. According to this parameter, pipes can be square or round. There are also ribbed and multifaceted versions.
- The accuracy class plays an important role. In the case of the first class, the trimming will be neat, no extra components will remain. In the case of the second class, only trimming is performed, some burrs may remain.
