Full Description

Preface:

This is the third edition of the CSA Z245.20 Series, Plant-applied external coatings for steel pipe, which consists of the eighth edition of CSA Z245.20, Plant-applied external fusion bond epoxy coating for steel pipe, the seventh edition of CSA Z245.21, Plant-applied external polyethylene coating for steel pipe, and the third 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 2014, 2010, 2006, 2002, 1998, 1992, and 1986; this edition of CSA Z245.21 supersedes the previous editions published in 2014, 2010, 2006, 2002, 1998, and 1992; and this edition of CSA Z245.22 supersedes the previous editions published in 2014 and 2010.

CSA Z245.20 deals with the requirements for plant-applied external fusion bond epoxy coating for steel pipe. The main differences from the previous edition are as follows:
  • updated definitions (Clause 3); and
  • revised test procedures (Clause 12).
CSA Z245.21 deals with the requirements for plant-applied external polyethylene coating for steel pipe. The main differences from the previous edition are as follows:
  • revised product ordering requirements (Clause 4.1);
  • revised requirements for the repair of coated pipe (Clause 8);
  • revised test procedures (Clause 12); and
  • revised acceptance criteria for polyethylene (Tables 3 and 9).
CSA Z245.22 deals with the requirements for plant-applied external polyurethane foam insulation coating for steel pipe. The main differences from the previous edition are as follows:
  • revised test procedures (Clause 12);
  • revised coating system qualification tests (Table 2); and
  • revised acceptance criteria for polyethylene (Table 5).

Z245.20-18 - 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 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 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.

Z245.21-18 - 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 A: a coating that consists of an adhesive and a polyethylene outer sheath (see Table 1);
b) System B1: a coating that consists of a liquid or powdered epoxy primer, a polymeric adhesive, and a polyethylene outer sheath; and
c) System B2: a coating that consists of a powdered epoxy primer, a powdered copolymer adhesive, and a powdered polyethylene outer layer.

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.

Z245.22-18 - 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 layer, or a leak detection and monitoring system (LDMS), or a combination thereof;
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 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.
