About This Item


Full Description


This is the third edition of CSA B242, Groove- and shoulder-type mechanical pipe couplings.

It supersedes the previous editions published in 1980 and 1971. It is written in SI (metric) units.

1 Scope

1.1 This Standard covers groove-type mechanical pipe couplings for liquid and gas pressure pipes up to and including NPS-42 and shoulder-type mechanical pipe couplings for liquid and gas pressure pipes up to and including NPS-60.

1.2 This Standard includes minimum requirements for materials, chemical properties, physical properties, pipe groove and shoulder dimensions, finishes, and pipe coupling markings.

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; "may" is used to express an option or that which is permissible within the limits of the standard; and "can" is used to express possibility or capability.

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.
