From a solid billet, cast pipes are obtained that have no seams, are free of flaws and defects. Despite the fact that the number of materials is constantly replenished with new analogues, seamless tubular products are also widely used in all aspects of human activity. Such products belong to the field of ferrous metal rolling and are often chosen for the transportation of gases and liquids.
Advantages of Seamless Steel Pipes
Steel seamless pipes are divided into cold and hot rolled. It is advisable to use both those and others in critical areas due to the fact that they differ in increased strength. Moreover, seamless steel pipes have other equal advantages:
- high thermal conductivity;
- low coefficient of linear expansion;
- less roughness;
- clean surface;
- maximum reliability.
Usually seamless analogs are made from cylindrical blanks, thanks to which the required shape can be achieved during the production process. The outer diameter and wall thickness are the main parameters on which they rely in the final choice of rolled metal.
Cold and hot forming
In the process of obtaining hot-deformed tubular products, the billet is passed through the rollers and begins to stretch in a hot state, shaping and cooling in containers with water. The resulting product is adjusted to the size and defects are eliminated in it.
With cold deformation, the pipe billet enters the production cycle in a cold state. Its qualities are improved by annealing, after which the pipe is cooled and recrystallized. Ultimately, the required wall thickness is removed and defects are eliminated.
The range of seamless pipes is formed on the basis of the following indicators:
- sizes;
- precision manufacturing;
- surface quality;
- mechanical properties;
- tolerances;
- protective properties;
- steel grades.
