API 5L X52 Line Pipe

API 5L X52 Line Pipe is high carbon alloy steel pipes. This results produced line pipe is harder due to the addition of carbon amount. During the formation of pipes carbon addition increase toughness and hardness, however, it reduces strength.
These line pipes are used in the conditions where wear, tear and abrasion reductions are the main concerns. These pipes are suitable for piping applications. In construction and fabrication, the grade and composition of pipes used to make a huge impact on the end pipes. The line pipes are common boasts as tougher quality and harder four times as standard grades.

These pipes are made by quenching and tempering process. While the manufacturing process, the grain structure is changed to increase the toughness and improve formability that results in hardening of materials.
These line pipes have great resistance to crevice and pitting corrosion in terms of adverse environments. The line pipes have high temperature stability without any deformation and elongation. These pipes have great elevated strength in stress corrosion cracking environments where the issue is sulfides, chlorine, nitric acids, phosphoric acids, sulfuric acids, chlorides, halides, and more. Also, these line pipes are exposed in the process streams. Line pipes can be applied in the environments where grain boundary precipitation is a concern. The reheating of line pipes break down crystal structure formed in the quenching process. The long lasting cooling allows crystal structure reform and maintaining the strength and hardness but increase overall ductility.

Moreover, the heat treatment and annealing process are performed on the pipes to achieve the desired mechanical strength and ductility. Furthermore, the cold working operations are performed to prevent embrittlement while retaining adequate mechanical dimensions.
The line pipes get the desired dimensions and accurate finish after the industrial finishing process. Moreover, these are processed from industrial coats that prevent additional protection from the oxidation.
