Foreword

GB/T 19831 is divided into two parts. --- Petroleum and natural gas industries - Casing centralizers - Part 1. Bow - spring casing centralizers --- Cementing oil and gas industry equipment - Part 2. centralizer placement and snap ring test This section GB/T 19831 Part 2. This part identical with ISO 10427 2.? 2004 "oil and gas industry --- --- centralizer cementing equipment placement and testing stopper ring Again "(in English). For ease of use, this section made the following editorial changes. a) "ISO 10427 Part" be replaced by "this section"; b) use a decimal point instead of a decimal comma ",". ","; c) Remove the ISO 10427 2.? 2004 foreword and introduction, an increase of this preface. Appendix A of this section is an informative annex.
