Steel pipe thin-walled: types, classification, scope

Nowadays pipes are used practically in all branches of human activity and are encountered almost at every step. It's hard to imagine how you can build communication without them. For the arrangement of water, gas, heating and other systems, metal-plastic, polypropylene, polyethylene, steel and copper pipes are used. The choice is so diverse that it is sometimes very difficult for a simple person to deal with this independently.

For example, for the installation of gas pipelines, a thin-walled steel pipe is best suited. It is also used in mechanical engineering as one of the elements of metal structures. In addition, it often plays the role of a shaft and is used to produce various structural elements.

With the help of steel pipes, you can solve many engineering problems. They are metal products made from carbon steel grades. This technology involves arc and gas welding.

Types of pipes

The modern steel thin-walled pipe is represented by two varieties:

• Seam (welded);
• Seamless.

According to the type of material used, the pipes are distinguished from black metal and stainless steel. Such products in addition to varieties can have different sections: square or rectangular. Each of these types of pipes is intended for a particular area of activity.

Basic classification parameters

A thin-walled steel pipe is classified according to the following parameters:

• The length of the finished product.
• The thickness of the material (in this case, steel).
• A definite shape of the section.

Thin-walled steel pipe: diameters, technical characteristics

The main characteristics of pipe products are the dimensions and strength level. The latter is the ability to withstand the nominal pressure, and as far as the dimensions are concerned, the outer and nominal diameters are meant. The ratio of these parameters plays a significant role, so the choice of this value should be approached very carefully, observing the standard boundaries, which range from 12.5 to 40 units. For example, a steel thin-walled pipe, the diameter of which should not exceed 20 mm, has a wall thickness of at least 1.5 mm.

Scope of application

Pipes made of steel allow to ensure uninterrupted supply of water and gas, and also cable lines are laid inside them. Therefore, in the near future it is absolutely impossible to refuse them, in spite of the fact that today there are active attempts to create an alternative in the form of plastic with similar properties.

Steel pipe thin-walled with a sufficiently large diameter is used for laying sewer galleries and collectors. Here, the most effective technology of extrusion by individual links is used. When installing such products, various hydraulic devices are used, making the pipes to be joined to each other.

The popularity of steel pipes

Steel pipe thin-walled surpasses other products of this kind of strength and durability. This means that one unit can be used for many years. Therefore, it is steel pipes that are the most suitable option for the construction of private houses, stalls and other light structures. When installing a heating system, such steel materials should not be used because permanent exposure to high temperatures can cause deformation and failure of the entire system, and this will entail additional financial costs.

Due to active introduction of advanced technologies, steel pipes are provided with the necessary mechanical strength and rigidity. As for the price of such products, it is the most democratic of all available today.
