  6. revised requirements for notch-toughness tests
  7. new requirements for special counterbore end preparation option
  8. revised requirements for elevated temperature service
  9. and revised requirements for material test reports.

This Standard was prepared by the Subcommittee on Materials, under the jurisdiction of the Technical Committee on Petroleum and Natural Gas Industry Pipeline Systems and Materials and the Strategic Steering Committee on Liquid and Gaseous Energy Systems, and has been formally approved by the Technical Committee

Scope
1.1 General

This Standard covers wrought steel buttwelding fittings, including extruded headers, primarily intended for use in oil or gas pipeline systems. Note: Induction and cold bends are covered in CSA Z245.16 and CSA Z245.17, respectively.

1.2 Size, grade, and category 1.2.1 Size

This Standard covers fittings in sizes from NPS 1/2 to NPS 60 (see Table A.1).

1.2.2

Grade Other than sour service, this Standard covers fittings from Grade 207 to Grade 690. For sour service, this Standard covers fittings from Grade 207 to Grade 483.

Note:

  1. The standard grades are Grades 207, 241, 290, 317, 359, 386, 414, 448, 483, 550, 620, and 690 (see Table
  2. ; however, intermediate grades are addressed in Clause 9.2.2
1.2.3 Category

This Standard covers fittings in the following categories

  1. Category I: fittings without requirements for proven notch-toughness properties
  2. and Category II: fittings with requirements for proven notch-toughness properties.

Note: A fitting cannot be classified as Category II if it has not been notch-toughness tested

1.3 Assemblies

This Standard does not cover assemblies. Note: An assembly means a grouping of fittings or flanges, or both, joined by one or more circumferential welds.

1.4 Terminology

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.
