Seamless pipe - this is one of the key elements in the construction of industrial and building communication systems.Due to the lack of joints in the construction of such components we can say that they are among the most durable in its kind.Practice shows that seamless tubes really are characterized by high resistance to physical and mechanical stress, and therefore - have high performance.
Scope
As we have noted, these parts have high performance.It is because of these qualities, they are applied to those objects which require high reliability.For example, a thick-walled models of these devices are used in the laying of 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 in municipal services.Also worth noting is that most of the products manufactured in the CIS countries (GOST 8732-78 Seamless pipe included) comes on imports of many countries in Europe.
Species
wall thickness These products are divided into two types:
- Thick.
- Thin.
The width of the walls of the first type of detail varies from 12.5 to 40.0 millimeters.Thin-walled tubes - Seamless cold - wall has a width of 6 to 12.5 millimeters.
tolerance and precision data-diameter pipe can be divided into conventional products and products of high accuracy.The very length of the steel member can be from 4 to 12.5 meters and more.
Material
often seamless pipes made of high-strength alloy or carbon steel.Both materials are characterized by high reliability and performance.With this seamless pipes are maximally resistant to corrosion, corrosive substances and other chemical reagents.
Depending on what type of steel was used in the design of products, experts there are several types of seamless pipes:
- standardization of mechanical properties.
- standardization chemical composition.
- with a valuation of both (chemical and mechanical) characteristics.
- Not to the properties and composition.
way, the methods of manufacturing these four parts.This can be: forging, rolling, pressing or drawing.However, whatever method of manufacturing not used, such products will always be the most durable and resistant to aggressive external factors.
Conclusion
Thus, seamless tubes are one of the most durable and resistant products used in industrial and municipal communications.Such a wide range of applications due to the high performance of this product.And this, in turn, a special seamless method of manufacture and use of the most durable types of steel - alloy and carbon.
