Industrial Protective Coatings And Linings Corrosion Inspection Management
The word “coating ” is a generic term and includes “paint.” In the most general terms, a “coating” is protection against corrosion, whereas a “paint” may have additional properties such as color or ultraviolet screening pigments. The terms “coating ” and “paint” are used interchangeably most of the times.
Other terms often used together are “ coatings” and “linings.” In general, when describing the interior surfaces of pipes or tanks, the term “linings” is used to identify the interior
surfaces and “coatings” is used to identify the exterior surfaces.

Protective or industrial coatings are the primary means employed to control corrosion.

Service Exposure:

Coatings are specified by service exposure or the environment the coating will be subject to. The following are the basic service exposures defined:

• Atmospheric - Indoors, Outdoors
• Buried
• Immersion
• Complete, partial, or fluctuating immersion conditions
• Atmospheric exposure subject to condensation, high humidity, splash, or spray
• The following sub-exposure conditions may apply to any of the above:

Direct sunlight or UV: several coatings, such as epoxies, will deteriorate by chalking when exposed to sunlight.

Chemical resistance: exposures may include acidic or alkaline concentrations, industrial smog, acid rain, sewage, or specific chemicals.
