GB/T 31944-2015Corrosion resistant steel plates for cargo oil tanks (English PDF)

Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules. The standard proposed by China Iron and Steel Association.

1 Scope

This standard specifies the crude oil cargo tanks with corrosion-resistant steel grades that way, ordering the content, size, shape, weight and allow partial Poor, technical requirements, inspection and testing, packaging, marking and quality certificate.

This standard applies to the manufacture of crude oil cargo tank deck and internal floor area of \u200b\u200bnot more than 50mm thickness of the corrosion-resistant steel (hereinafter He said plate). Steel can be performed with reference to this standard.
