GB/T 3091 specifies that pipes with a diameter of DN500 or less can be delivered in galvanized form. So what should be done if pipes larger than DN500 are to be used as galvanized pipes? I would appreciate some guidance from experts, thank you!

That’s also an option, but the first thing to do is to find a manufacturer, as some manufacturers are not capable of producing pipes for very large-diameter wells
