1 Scope 1.1 This Standard covers the qualification, application, inspection, testing, handling, and storage of materials required for plant-applied fusion bond epoxy (FBE) coating applied externally to bare steel pipe. The coated pipe is intended primarily for buried or submerged service for oil or gas pipeline systems. 1.2 This Standard covers the following coating systems: (a) System 1A: single-layer FBE with a glass transition temperature of 115 °C or less; (b) System 1B: single-layer FBE with a glass transition temperature greater than 115 °C; (c) System 2A: two-layer FBE with an anti-corrosion coating and a protective overcoat; (d) System 2B: two-layer FBE with an anti-corrosion coating and an abrasion-resistant overcoat; (e) System 2C: two-layer FBE with an anti-corrosion coating and an anti-slip overcoat; and (f) System 3: three-layer FBE with an anti-slip overcoat applied over an anti-corrosion coating and a protective overcoat. 1.3 In CSA Standards, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; “should” is used to express a recommendation or that which is advised but not required, and “may” is used to express an option or that which is permissible within the limits of the standard. Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material. Notes to tables and figures are considered part of the table or figure and may be written as requirements. Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.
