Description

Preface

This is the fourth edition of CSA B137.3.1, Molecularly oriented polyvinylchloride (PVCO) pipe for pressure applications. It supersedes the previous editions published in 2013 and 2009.

While earlier editions of this Standard were published as part of the CSA B137 Series, Thermoplastic pressure piping compendium, the third edition was reissued as a stand-alone Standard in January 2019. The compendium format has been discontinued.

This Standard is to be used with the 2020 edition of CSA B137.0, which provides requirements and test methods that are common to some or all of the Standards of the CSA B137 series.

The major changes in this new edition are

a) clarification of impact resistance for pipe sizes NPS-14 or larger in Clause 5.6.3;

b) addition of Note to Clause 5.7 on oil-resistant materials;

c) correction of pressure rating for CIOD pipe in Tables 1, 5, and 7; and

d) addition of oil-resistant gaskets and liquid immersion test to Table 8.

This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.

Scope

1.1

This Standard covers molecularly oriented polyvinylchloride (PVCO) pipe intended for use in pressure applications such as water mains, sewer force mains, and process piping.

Note: This Standard does not address chemical compatibility between PVCO pipe and process fluids. Where PVCO pipe is to be used in non-water applications, the manufacturer should be consulted.

1.2

PVCO complying with this Standard is not suitable for solvent cementing and is intended to be joined by gasketed joints.

1.3

This Standard specifies requirements for materials, quality of work, dimensions, markings, hydrostatic sustained pressure, extrusion, impact resistance, and quality for PVCO pipe.

1.4

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.
