Preface
This is the fifth edition of CSA G401, Corrugated steel pipe products. It supersedes the previous editions, published in 2007, 2001, 1993, and 1981.
Changes have been made to this Standard to permit materials, manufacturing methods, and inspection procedures that meet appropriate current and projected industry practices. These changes include the following:
a) adding requirements for structural plate Type II, deep corrugated structural plate Type III, and tunnel liner plate corrugated steel pipe (CSP) products, including product specifications, sheet layout, and installation requirements;
b) adding requirements for polymer coating for structural plate products;
c) adding requirements for flange connections for structural plate and deep corrugated structural plate Types I and III;
d) changing requirements for chemical limits of structural plate;
e) adding requirements for alternative fasteners for applications in more aggressive environments;
f) removal of the requirements for asphalt and mastic coatings; and
g) updating the list of reference standards in Clause 2.
This Standard is considered suitable for use for conformity assessment within the stated scope of the Standard.
The development of this Standard was made possible thanks to the leadership and financial support of the Corrugated Steel Pipe Institute (CSPI). Such support does not indicate endorsement of the contents of this Standard.
This Standard was prepared by the Technical Committee on Corrugated Steel Pipe Products, 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 approved as a National Standard of Canada by the Standards Council of Canada.
