Hydrogen pipeline
Thread Content
200 kg hydrogen pipeline (normal temperature), the pipe and flange material is 316, the flange uses an annular groove sealing surface, how to choose the corresponding annular gasket? (The corresponding gasket material given on the hydrogen station is hard steel cardboard or copper plate, but there is no corresponding material gasket in hg20633)
It should be RJ, ring groove, and then look at the temperature-pressure allowable pressure. You need to be cautious about this. If you use annular gaskets, the hardness must be the main factor. Generally, the gasket hardness is lower than the flange material hardness, 30HB lower. As a reference, then look again. If the working conditions should reach GC1, you must be cautious. It is best to consult similar manufacturers to see what the current usage is like, and then benchmark to see if the load does not meet the current standard requirements.
There are only requirements for material hardness. Are there any requirements for specific materials?
I don’t know about this. I have only been exposed to hydrogen pipelines of 20 kg and below.
To use RJ, the gasket is an octagonal pad, and the material is high nickel 316L. There are many designs of this kind.
Is this a job to take over from Tian Jiayi?
