Product Details
Preface
This is the fifth edition of CSA B137.3.1, Molecularly oriented polyvinylchloride (PVCO) pipe for pressure applications. It supersedes the previous editions published in 2020, 2017, 2013, and 2009.
This Standard is to be used with the 2023 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 to this edition are updates to the ozone resistance test conditions and requirements in Table 8and the markings in Clause 7.
This Standard is considered suitable for use for conformity assessment within the stated scope of the Standard.
This Standard was prepared by the Technical Committee on Plastic Pressure Piping, under the jurisdiction of the Strategic Steering Committee on Construction and Civil Infrastructure, and has been formally approved by the Technical Committee.
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 General
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 Joining method
PVCO complying with this Standard is not suitable for solvent cementing and is intended to be joined by gasketed joints.
1.3 Requirements
This Standard specifies requirements for materials, quality of work, dimensions, markings, hydrostatic sustained pressure, extrusion, impact resistance, and quality for PVCO pipe.
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.
