GB/T29465-2012: Minimum thickness of butted cylinders
Thread Content
Clause 5.5 of GB/T29465-2012 stipulates that when the thickness of the butt cylinder connected to the side flange is less than the minimum butt cylinder thickness δ0 specified in Table 3, the total flange height H shall be adjusted in accordance with the requirements of Table 3, and this value together with the flange thickness shall be indicated on the flange markings. Does Table 3 here refer to the amendment table attached to NB/T47023? No amendment table was found in GB/T29465-2012. I would like to ask everyone: when encountering this issue, should one refer to the amendments in NB/T47023?

And then there’s the sentence behind that: together with the flange thickness. . . In fact, it is specified together with the flange height H in the flange markings. . . Those people in China who set standards. Ah, just casual like that
GB-T 29465-2012: Side flanges for external covers of floating-head heat exchangers. Table 3 is included in this standard; dear user, could it be that you’re referring to the wrong standard?
