Features of steel profile pipes

Among the huge number of steel pipes, profiles are most popular, which, depending on the shape of the cross section, are divided into several types. Profile pipes are considered all those that have a cross section that is different from the round.

In almost all construction works, a profile square pipe is widely used, its demand is explained quite simply, because such a pipe can significantly reduce construction costs, namely metal structures. Moreover, a special form of section contributes to the fact that the pipe has sufficient rigidity.

The use of high -quality metal for the manufacture of the pipe contributes to the fact that it differs in the proper level of quality and reliability, the average service life of such a pipe exceeds 5 years, it increases significant if the pipe is galvanized, because in this case, it is not terrible of corrosion.

Today, specialized steel pipes are made in accordance with all the requirements of GOST 13663-86. In most cases, the pipe is made using the method of deformation. The choice of it is precisely due to the fact that in this method of manufacturing, the high accuracy of the size can be observed. In addition, it is possible to make such a pipe using a seamless way. Note that profile pipes are produced mainly from electric welding or straight -line pipes. To get one of the specified types of pipes, a special workpiece is required, the role of which is usually a round pipe.

The creation of a profile pipe is carried out through cold or hot deformation. Depending on the purpose of the pipe, the technology of its production, they make one that has a certain shape and size. If in the process of manufacturing it is necessary to remove the internal mechanical voltage, then the pipe can be subjected to heat treatment. There are other manufacturing methods during which you can get:

electric welding pipe,

cold – and hot -formed,

Electric welding, cold -deformed.

We add that the pipe is profile square, however, like a rectangular one, has a variety of sizes, which allows you to choose one that is in great way to solve a variety of problems. The thickness of the walls of the profile pipes varies from 1 and to 12 mm, the length, in accordance with the requirements of GOST, can be from 6 and to 12 meters. Pipe steel may be as follows: ST2KP, ST2SP, ST2PS, ST4PS, ST4KP, as well as ST4SP.

Corner ribs of stiffness contribute to the fact that the steel pipes of the profile type are quite resistant to various mechanical loads, which is why this kind of pipes is the optimal solution for loading and unloading, during cargo transportation, etc. p. In addition, they allow designers and architect to find various non -standard solutions for design projects.
