Regarding several types of flanges
Thread Content
The standards used for pressure vessel flanges include the JB/T4701 series, HG20615 or HG20592 series – what else? I’ve heard recently that there is a GB9119-2000 standard. I would appreciate it if experts could share their insights and explain the differences in their use
JB/T4701 series for pressure vessel flanges; HG20615 or HG20592 series for pipe flanges
Flanges used for pressure vessels include: JB/T4701 series pipe flanges, HG series, GB series, JB series, GB marine series, SH series, ASME series, etc
Additional information for the second floor: The pipe flanges are of types HG20615 or HG20592; one is based on American standards and the other on European standards. Larger diameter pipes generally use those based on American standards. In practice, the standard used is mainly determined by the requirements specified in the customer’s specification sheet, as it needs to be in line with the standards of the user’s entire system.
There’s no requirement for “large-caliber items to use American standards”, right? Hey, the person above! According to the specification diagram, it’s correct
Does anyone know about GB9119?
Of course I know, I have standards too. A set of drawings designed five years ago used these standard flanges
The German DIN standards have equivalents to our container flange standards; I used them in a project with BAYER in the past. I can’t remember the specific standard numbers, but I can look them up if anyone needs them. This post was last edited by yangtzeliu on 2009-4-17 at 16:31.]
There is also SH3406-96, a petrochemical standard
GB9119 is a **standard flange; I’ve seen this standard – you can search for it online where it’s available for download
