GB/T 30059-2013Seamless corrosion-resisting alloy tubes for heat-exchanger (English PDF)

Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules.

The standard reference ASMESB-163 (2010 Edition) "Seamless Nickel and Nickel Alloy Condenser and heat exchanger tube" and ASMESB-444 (2010 Edition) "Nickel - chromium - molybdenum - niobium alloys (UNSN06625) and nickel - chromium - molybdenum - silicon alloy (UNSN06219) nominal pipe and tube" to develop. The standard proposed by China Iron and Steel Association.

1 Scope

This standard specifies a heat exchanger corrosion resistant alloy seamless ordering content, size, shape, weight and tolerance, technical requirements, test Test methods, inspection rules, packaging, marking and quality certificate content.

This standard is applicable for use in corrosive media nickel-based, iron-nickel-based heat exchanger corrosion resistant alloy cold-rolled (pull) seamless pipe (hereinafter referred to as Alloy tube). Alloy tube can refer to use for other purposes.
