Are there any standards for the dimensions of flanges on pipes when they exceed DN2000?
Thread Content
If the size of the flanges on the pipeline exceeds DN2000, are there any standards? And if no standards exist, how should it be calculated?
Flanges of such a large diameter are rarely used in industrial processes. You can refer to the flanges specified in AWWA standards; additionally, you can provide the operating conditions to the equipment specialists or manufacturers so that they can assist you with this.
The larger it is, the lower the pressure. . . EN1092
We calculate it ourselves; the methods are provided in GB150
If it’s larger, it doesn’t belong to the process piping anymore, right?
Yes, nowadays devices are getting larger and larger, which results in many non-standard components
It should fall pretty much under the category of containers, right?
Let’s look at the specialized roles of each department. In our unit, the non-standard components related to pipelines are still handled by the pipeline department
:Lol, we have made aluminum alloy flanges for DN2800
It is possible to refer to GB150 and EN1092, and set the values according to the operating conditions.
