Nowadays, pipes are used in almost all areas of human activity and are found at almost every step. It is hard to imagine how communication can be made without them. To equip 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 an ordinary person to independently deal with this.
For example, a thin-walled steel pipe is best suited for installing gas pipelines. 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 obtain various structural elements.
Steel pipes can solve many engineering problems. They are metal products made from carbon steel grades. At the same time, arc and gas welding technologies are involved .
Types of pipes
Modern steel thin-walled pipe is presented in two varieties:
- suture (welded);
- seamless.
According to the type of material used, pipes made of ferrous metal and stainless steel are distinguished. Such products, in addition to varieties, can have different sections: square or rectangular. Each of these types of pipes is intended for a particular field of activity.
Key classification parameters
Thin-walled steel pipe is classified by the following parameters:
- The length of the finished product.
- The thickness of the material (in this case, steel).
- A certain sectional shape.
Thin-walled steel pipe: diameters, technical characteristic
The main characteristics of tubular products are dimensions and strength level. The latter is the ability to withstand nominal pressure, and as for the dimensions, we mean the outer and nominal diameters. The ratio of these parameters plays a significant role, therefore, the choice of this value must be approached very carefully, observing standard boundaries that range from 12.5 to 40 units. For example, a thin-walled steel pipe, the diameter of which should not exceed 20 mm, has a wall thickness of at least 1.5 mm.
Scope of application
Steel pipes allow for an uninterrupted supply of water and gas, and cable lines are laid inside them. Therefore, in the near future it is absolutely impossible to refuse them, despite the fact that active attempts are being made to create an alternative in the form of plastic with similar properties.
A thin-walled steel pipe with a sufficiently large diameter is used when laying sewer galleries and collectors. It uses the most efficient punching technology for individual links. During the installation of such products, various hydraulic devices are used that connect the pipes to each other.
The popularity of steel pipes
Thin-walled steel pipe surpasses other products of this kind in terms 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 arranging a heating system, such steel materials are not recommended, since the constant influence of high temperatures can cause deformation and failure of the entire system, and this will entail additional financial costs.
Due to the 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 affordable of all available to date.
