Can hydrogen compressors use bellows heat exchangers?
Thread Content
Bellows heat exchanger, compressed hydrogen, flow rate 3000Nm3, pressure less than 5.0Mpa, 12* Can the stainless steel corrugated pipe of 1 be used?
Hydrogen is an explosive medium and cannot be used. It is not suitable for explosive media.
The inapplicable occasions listed in Appendix K of GB/T 151-2014 refer to thin-walled corrugated pipes processed by the internal expansion method, that is, according to GB/T 28713.2-2012 "Enhanced heat transfer elements for shell and tube heat exchangers - Part 2: Stainless steel bellows》standard processed bellows. It should be possible to use thick-walled corrugated pipes processed by external rolling according to GBT 24590-2009 "Special Tubes for High-Efficiency Heat Exchangers".
