Preface

This is the first edition of the CSA Z245.20 Series, Plant-applied external coatings for steel pipe, which consists of the sixth edition of CSA Z245.20, Plant-applied external fusion bond epoxy coating for steel pipe, the fifth edition of CSA Z245.21, Plant-applied external polyethylene coating for steel pipe, and the first edition of CSA Z245.22, Plant-applied external polyurethane foam insulation coating for steel pipe. This edition of CSA Z245.20 supersedes the previous editions published in 2006, 2002, 1998, 1992, and 1986, and this edition of CSA Z245.21 supersedes the previous editions published in 2006, 2002, 1998, and 1992.

Z245.20-10 Plant-applied external fusion bond epoxy coating for steel pipe

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 110 °C or less;
(b) System 1B: single-layer FBE with a glass transition temperature greater than 110 °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.

Z245.21-10 Plant-applied external polyethylene coating for steel pipe

Scope
1.1
This Standard covers the qualification, application, inspection, testing, handling, and storage of materials required for plant-applied polyethylene coating applied externally to steel pipe, whereby an adhesive is interposed between a bare or epoxy-primed pipe and the polyethylene. 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 A1: a coating that consists of an adhesive and a polyethylene outer sheath;
(b) System A2: a coating that consists of an adhesive and a polyethylene outer sheath that has more stringent peel adhesion requirements than those for System A1 (see Table 1);
(c) System B1: a coating that consists of a liquid or powdered epoxy primer, a polymeric adhesive, and a polyethylene outer sheath; and
(d) System B2: a coating that consists of a powdered epoxy primer, a powdered copolymer adhesive, and a powdered polyethylene outer layer.

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.

Z245.22-10 Plant-applied external polyurethane foam insulation coating for steel pipe

Scope

1.1
This Standard covers the qualification, application, inspection, testing, handling, and storage of materials required for plant-applied external polyurethane foam insulation coating to steel pipe. The coated pipe is intended primarily for buried or submerged service for oil or gas pipeline systems.

1.2
This Standard applies to foam insulation coating composed of
(a) anti-corrosion coating;
(b) polyurethane foam insulation; and
(c) external polyethylene jacket.

1.3
This Standard covers spray-applied or moulded polyurethane foam insulation coating systems.

1.4
This Standard does not cover material requirements for steel pipe and cryogenic applications.

1.5
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.
