Steel pipe 50×25.
A steel pipe 50×25 usually has a length of 6 m., and on the cut is presented in the form of a rectangle. This type of metal product refers to the profile – at the factories it is made using hot or cold formation. The most durable, but in turn, quite expensive, are hot -formed pipes. They have a different wall thickness, which is from 1.5 to 4 millimeters and a step half a centimeter. The quality of materials is determined by GOST 8645-68, which indicates information on inertia and resistance, which is taken into account when designing. Thanks to special welding, this product is used for construction and design. It is the most popular in the market of metal rolling.
Significant disadvantages of a 50×25 steel pipe include the exposure of corrosion. But this is eliminated due to a special zinc coating – it is it that prevents rusting.
Positive factors include a low temperature regime and a linear expansion coefficient. It is also necessary to take into account the fact that such pipes have excellent heat capacity.
In the special documentation, the main characteristics of the pipe are indicated by special symbols. Based on the data, we see that the product is a steel pipe of the ST08 brand with a rectangular cross section, the long side reaches 50 millimeters, and the short – 25 millimeters, the wall of the pipe with a thickness of 3 millimeters. The service life of a steel pipe 50×25 is from 30 to 40 years. That is why it will be in great demand, even though a number of shortcomings.
