While standards like ASME B31.3 handle general process piping, is specifically engineered to address the unique challenges of hydrogen. Hydrogen molecules are incredibly small and can cause "hydrogen embrittlement," making standard steel brittle and prone to cracking. The code is divided into three primary parts: Part IP: Industrial Piping (Refineries and chemical plants) Part PL: Pipelines (Long-distance transport)
