Full Description

Preface

This is the third edition of CSA Z245.30, Field-applied external coatings for steel pipeline systems . It supersedes the previous editions published in 2018 and 2014. This Standard covers the requirements for external coatings for buried or submerged piping as specified by CSA Z662. The major changes to this edition are the following: a) added a definition for Non-editorial change, MQAP; b) added requirement for digital surface contact thermometer; c) revised requirements for holiday inspection; d) revised test procedures for hardness and peel adhesion; e) revised manufacturer qualification coating test requirements for all FC systems; f) revised applicator qualification and coating quality test requirements for Systems FC1, FC2, FC3, FC4, FC5, and FC7; and g) added new Annex A on holiday inspection of existing coating. This Standard was prepared by the Subcommittee on Coatings, under the jurisdiction of the Technical Committee on Petroleum and Natural Gas Industry Pipeline Systems and Materials and the Strategic Steering Committee on Petroleum and Natural Gas Industry Systems, and has been formally approved by the Technical Committee.

Scope

1.1 This Standard covers the qualification, application, inspection, testing, handling, and storage of materials required for coatings applied externally to steel piping in the field or a shop. Coated piping addressed by this Standard is intended primarily for buried or submerged service in oil or gas pipeline systems.

1.2 This Standard covers the following coating systems: a) System FC1: liquid-applied epoxy or fusion bond epoxy (FBE) with a glass transition temperature of 115 °C or less; b) System FC2: liquid-applied epoxy or FBE with a glass transition temperature greater than 115 °C; c) System FC3: liquid-applied epoxy or FBE intended for abrasion service; d) System FC4: adhesive and a polymeric backing (e.g., tape, heat shrinkable sleeve); e) System FC5: epoxy primer, adhesive, and a polymeric backing (e.g., tape, heat shrinkable sleeve); f) System FC6: anti-corrosion coating, if applicable [see Items a), b), d), and e)], polyurethane foam insulation, and a polymeric backing with or without adhesive (e.g., tape, heat shrinkable sleeve); and g) System FC7: fibre-reinforced petrolatum, paraffin-filled, or visco-elastic systems.

1.3 In this Standard, "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.
