Seamless pipes are one of the main elements in the construction of industrial and building communication systems. Due to the absence of seams in the design of such parts, we can say that they are among the most durable of their kind. As practice shows, seamless pipes are indeed characterized by increased resistance to physical and mechanical stress, and therefore have high performance characteristics.
Scope of application
As we have already noted, these parts are characterized by high performance. It is because of these qualities that they are used in those facilities where greater reliability is required. For example, thick-walled models of these devices are used when laying water and gas pipelines. Hot-rolled seamless pipes are widely used in the oil and gas industry and mechanical engineering. In addition, these products are used inpublic utilities. It is also worth noting that most of the products manufactured in the CIS countries (including seamless pipe GOST 8732-78) are imported to many European countries.
Varieties
According to the wall thickness, these products are divided into two types:
- Thick-walled.
- Thin-walled.
The width of the walls of the first type of parts varies from 12.5 to 40.0 millimeters. Thin-walled pipe - seamless cold-formed - has a wall width of 6 to 12.5 millimeters.
According to the accuracy of manufacturing the diameter, these pipes can be divided into ordinary products and high-precision products. The length of the steel element itself can be from 4 to 12.5 meters or more.
Material
Often, seamless pipes are made from high-strength alloy or carbon steel. Both materials are distinguished by high reliability and performance characteristics. Thanks to this, seamless pipes are highly resistant to corrosion, aggressive substances and other chemicals.
Depending on what type of steel was used in the design of the product, experts distinguish several types of seamless pipes:
- With standardization of mechanical properties.
- With standardization of chemical composition.
- With normalization of both (chemical and mechanical) characteristics.
- Without respect for properties and composition.
By the way, manufacturing methods
these parts are four. It can be: forging, rolling, pressing or drawing. However, no matter what manufacturing method is used, such products will always be as strong as possible and resistant to external aggressive factors.
Conclusion
Thus, seamless pipes are one of the most durable and resistant products used in industrial and municipal communication systems. Such a wide range of applications is due to the high performance characteristics of this product. And this, in turn, is a special seamless manufacturing method and the use of the most durable steel grades - alloy and carbon.
