Seamless pipes - characteristics and application

Seamless pipes are one of the main elements in the construction of industrial and construction communication systems. Due to the absence of seams in the construction of such parts, we can say that they are among the most durable in their kind. As practice shows, seamless pipes are indeed characterized by increased resistance to physical and mechanical influences, and consequently - have high performance characteristics.

Application area

As we have already noted, these parts are characterized by high performance characteristics. It is because of these qualities that they are used on those facilities where greater reliability is required. For example, thick-walled models of these devices are used for laying water and gas pipelines. Hot-rolled seamless pipes are widely used in the oil and gas industry and mechanical engineering. In addition, such products are used in the communal economy. It is also worth noting that most of the products produced in the CIS countries (seamless pipe GOST 8732-78 including) is supplied for import to many European countries.

Varieties

In terms of wall thickness, these products are divided into two types:

1. Thick-walled.
2. Thin-walled.

The width of the walls of the first type of parts varies from 12.5 to 40.0 millimeters. Thin-walled tube - seamless cold-deformed - has a wall width of 6 to 12.5 millimeters.

By the accuracy of the diameter, these pipes can be subdivided into conventional products and products of increased accuracy. The very length of the steel element can be from 4 to 12.5 and more meters.

Material

Often seamless pipes are made of high-strength alloyed or carbon steel. Both materials are characterized by high reliability and performance characteristics. Due to this, seamless pipes are as resistant to corrosion, aggressive substances and other chemical reagents.

Depending on the type of steel used in the design of the product, specialists distinguish several types of seamless pipes:

1. With the standardization of mechanical properties.
2. With the standardization of the chemical composition.
3. With the normalization of both (chemical and mechanical) characteristics.
4. Without respecting the properties and composition.

By the way, the manufacturing methods These details are four. This can be: forging, rolling, pressing or drawing. However, whatever method of manufacture would not be applied, such products will always be as strong as possible and resistant to the influence of external aggressive factors.

Conclusion

Thus, seamless pipes are one of the most durable and stable products used in industrial and communal communication systems. This wide range of applications is explained by the high performance characteristics of this product. And this, in turn, is a special seamless method of making and using the most durable grades of steel - alloyed and carbonaceous.
