What is the primary purpose of installing a metallic liner inside a vessel?

The primary purpose of installing a metallic liner inside a vessel is to resist corrosion. In many industrial applications, vessels are exposed to aggressive environments that can lead to corrosion of the base material. A metallic liner, typically made from a corrosion-resistant alloy, serves as a protective barrier between the corrosive contents and the vessel itself.

This protection is crucial because it extends the lifespan of the vessel, reduces maintenance costs, and enhances overall reliability. Corrosion can lead to structural integrity issues, leaks, or even catastrophic failures if left unaddressed, making the use of liners an important consideration in vessel design and maintenance.

While enhancing thermal conductivity, reducing weight, and improving pressure resistance may also be beneficial characteristics in certain contexts, these are not the primary motivations for the inclusion of a metallic liner. The intent behind such installations is fundamentally centered on safeguarding against the pervasive effects of corrosion.
