Dear NDT Experts I have a problem with a gasometer (Hydrogen Storage ) that will enter soon in operation, my concern is around the influence of the hydrogen. It is a Russian steel 16gc (0.16 C 1Mn 1Si), the design considerations are: 20m height. 3m diameter. 35mm thickness. Storage Temperature 38 degrees C Pressure 50 atm Would be critical, the effects of HIC or hydrogen damages, in this case?
