In summary, while both coating and lining are essential for protecting pipelines, they serve distinct purposes and are applied in different contexts. Coating focuses on external protection, shielding pipes from environmental factors, while lining addresses internal protection, safeguarding pipes from the substances they carry. Both processes offer significant benefits, including corrosion resistance, enhanced flow efficiency, et durée de vie prolongée. As technology continues to advance, the effectiveness and sustainability of coating and lining methods are expected to improve, ensuring the continued reliability and safety of pipeline systems across various industries.
