Pipe flanges for pressure vessels

Hello everyone: There is currently a heat exchanger with a design pressure of 0.8 MPa; the medium used is hydrogen, and the design temperature is 80°C. According to TSG21-2016, pressure vessels that store liquefied petroleum gas, media with extremely high or high toxicity levels, or media with high permeability and moderate toxicity levels require the use of wafer-type butt weld flanges. Here, by \"media with high permeability and moderate toxicity levels\", it refers to media that are either highly permeable or moderately toxic – in either case, wafer-type butt weld flanges must be used. I would appreciate some guidance from those who are more experienced, thank you
