GB/T 28413-2012Welded carbon steel tubes for boilers and heat exchangers (English PDF)

Foreword

This standard GB/T 1.1-2009 given rule drafting.

The standard reference to EN10217-1:2002 "welded steel tubes for pressure purposes - Technical delivery conditions - Part 1. Performance of non-cooperation with specified room temperature Gold steel ", EN10217-2:2002" welded steel tubes for pressure purposes - Technical delivery conditions - Part 2. specified elevated temperature properties of welded unalloyed And alloy steel tubes ", JISG3461-2005" boilers and heat exchangers with the preparation of carbon steel pipe. " The standard proposed by China Iron and Steel Association.

1 Scope

This standard specifies the welded steel pipe for ordering content, size, shape, weight, technical requirements, test methods boilers and heat exchangers, test Rules, packaging, marking and quality certification.

This standard applies to the heat exchanger and low pressure boiler with welded steel pipe, stainless steel welded pipe not apply.
