At least three of the ASME B31 piping codes are logical choices:
Considerations for code selection include:
The requirements of the code used for the original construction apply. The piping may meet the requirements of more than one code. In which case, the code used for changing the rating may be different than the original code of construction. In any case, the re-rated system should meet all of the requirements of the selected code. Note that if the original proof test of the system was…
The code used for repair and alterations of an existing system depends on the code used for construction as well as on the requirements imposed by the jurisdiction. Note that getting a permit from the jurisdiction may be necessary for an extensive alteration.

The HSP recommends against the use of glycols for pressure tests due to the difficulty of adequately removing all glycol that might be left in a system after a hydrotest. The HSP recommends a pneumatic test at 110% of the system maximum allowable working pressure (MAWP), which is acceptable by code. Due to an increased danger with pneumatics vs hydrotesting, establish a pressure test zone for… Category: Piping
The Panel recommends performing a pressure test at 110% of design pressure. This requirement should be applied to all systems regardless of construction type since the intent is to ensure pressure integrity and proper installation. All fitting types have modes of failure during installation. For example, there are numerous examples where compression fittings have had ferrules installed… Category: Piping

Each system should be evaluated for exposure of equipment to jet fires. The design team should develop Category: Site Planning Keywords: Fire Protection, Jet Fire, Fire Barriers, Hazards Analysis
Codes and standards to address issues like this one are under development, along with applied research and field trials. As with any new application, appropriate codes and standards must be developed to meet public risk targets. Category: Site Planning Keywords: Heating, Explosion, Setback Distance
Systems should be sited in accordance with national and local standards such as NFPA 2, Hydrogen Category: Site Planning Keywords: NFPA 2
Exposure between these products is bidirectional. A hazard analysis should consider what happens to Category: Site Planning Keywords: Multi-fuel Stations, Separation Distance
