Which specifications should be followed to select the pressure and temperature rating for pipe flanges? I know that there are HG standards in China, but what are the reference standards such as ASTM and ANSI abroad? Could you please provide more details?
In China, there are also SH/T 3406, ASME B16.5, and ASME B16.47 as well as ANSI B16.5
There are, right? . . I remember it. .
First, it is necessary to determine the standard for the flange; each standard has its own pressure-temperature chart, and they cannot be used interchangeably.
Some standards also exist; I heard that they have been incorporated by ASME.
The information is very useful; thanks to the original poster for sharing it.
