PE pipes are widely used in our daily lives, and everyone should be familiar with them. A good pipeline should not only have good economy, but also have a series of advantages such as stable and reliable interfaces, material impact resistance, cracking resistance, aging resistance, and corrosion resistance.
In fact, there are many processes and principles involved in the production of PE pipes. Today, we will introduce the relevant content of solid solution treatment for PE pipes, hoping to help everyone.
During the production process of PE pipes, the microstructure and mechanical properties of the material will change due to the high temperature effects of rolling, stretching, and welding, which seriously affects the quality of the pipe. These changes mainly include cold work hardening phenomenon, that is, the regular displacement of one or more columns of atoms in the crystal, lattice distortion, and the formation of a stress concentration zone, also known as dislocations.

Due to high temperature and uneven cooling,welding stress is generated and ferrite is formed in the original single austenite structure,resulting in uneven structures such as carbides.In order to improve production efficiency,ensure the surface brightness of the coil,eliminate residual stress,obtain a single austenite structure,and produce high-quality coils,it is necessary to implement online bright solid solution treatment method.
Through the above introduction,I believe everyone should have a better understanding of the solid solution treatment of PE pipes.I hope it can help everyone.When encountering such problems,one can quickly and proficiently solve them without delaying the project schedule.
