Flange fitting issues

Thread Content

I would like to ask whether there are any regulations regarding the length of the flange stub when connecting the flange to the cylinder What are the length requirements for flange connections of different sizes?

It seems there are regulations regarding this in GB150; you can check it out. The strength of the pipe fittings needs to be calculated, and it appears to be related to the length of the pipe fittings

For general flanges and valves, leave a gap of 1.5 to 2 MM for socket welding.
