Differences between the two welding standards

2016-12-06View Original

Thread Content

I need help understanding the differences between the two welding standards, HG/T20583 and JB/T4709. When designing atmospheric pressure storage tanks today, I encountered these two standards; I need help understanding the differences between them

JB/T4709 has been replaced by NB/T47015. . Check them separately – the standard focuses are different: HG/T20583 for the structural design of chemical vessels, and NB/T47015 for welding procedures for pressure vessels

One is design, and the other is craftsmanship
