The material has uniform thickness, smooth surface and high strength, and maintains its strength at high pressure and high temperature. It also has high wear resistance and impact resistance.
It is highly resistant to corrosion and has excellent pressure resistance. It will not deform or burst, ensuring the integrity of the pipeline. Long service life reduces the frequency of replacement.
