Definition - What does Cladding Flange mean?
A cladding flange is a flange on which an operation such as a weld overlay cladding has been performed. This operation is also performed on pipelines and pipeline equipment such as valves, rings, gaskets and flow control equipment. The basic purpose for performing this operation on a flange or any other industrial equipment is to provide a protective corrosion resistant layer on areas that are prone to corrosion or wear and tear while operating in harsh environmental conditions.
Corrosionpedia explains Cladding Flange
Cladding flanges make use of a weld overlay cladding technology process that builds up the corrosion resistant alloy (CRA) layer on the welded parts of pipes and other piping components (e.g., valves, flanges). It protects the piping system's integrity, and provides a low cost and long-term solution. The weld overlay cladding process is commonly applied on products used in an environment where there is a likelihood of corrosion, abrasion or cavitation erosion.
