What is cladding in the context of boiler construction?

In the context of boiler construction, cladding refers to a metal covering that protects the exterior of the boiler. This layer of metal serves several important functions: it enhances durability by providing a protective barrier against external elements, such as moisture and corrosion, which can lead to deterioration of the boiler's structural integrity over time. Additionally, cladding can help improve safety by insulating the boiler surface, thus reducing the risk of burns or heat transfer to surrounding areas.

In many cases, the cladding materials are chosen for their strength, resistance to heat and corrosion, and their ability to withstand the high-pressure environments often encountered in boiler operations. This protective metal layer is a crucial part of ensuring the longevity and reliability of the boiler system.
