This Standard covers the requirements for factory-made steel induction bends intended to be used for transporting fluids as specified in CSA Z662. As of this edition, induction bends and cold bends have been removed from CSA Z245.11, Steel fittings, and are now covered in CSA Z245.16 and Z245.17, respectively. CSA Group acknowledges that the development of this Standard was made possible, in part, by the valuable dedication of Maros Tropp and the financial support of ATCO Ltd., Benpro Technologies Corp., British Columbia Oil and Gas Commission, Enbridge Inc., FortisBC Energy Inc., TC Energy Corp., and Tectubi Raccordi S.p.A. (Allied Fitting). 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 Petroleum and Natural Gas Industry Systems, and has been formally approved by the Technical Committee. Scope 1.1 General This Standard covers the manufacturing of factory-made induction bends, primarily intended for use in oil or gas pipeline systems. 1.2 Size, grade, and category 1.2.1 Size This Standard covers induction bends from outside diameters (ODs) 60.3 to 1524 mm (NPS 2 to NPS 60, see CSA Z245.11 Table A.1). 1.2.2 Grade For other than sour service, this Standard covers bends from Grade 241 to Grade 690.
