6 - Standards and codes to control hydrogen-induced cracking in pressure vessels and pipes for hydrogen gas storage and transport

Abstract

This chapter discusses the American Society of Mechanical Engineers (ASME) codes and standards that have been developed for pressure vessels, piping and pipelines for high pressure gaseous hydrogen storage and transport. It does not cover codes and standards that apply to vehicle fuel tanks. The focus of this chapter is primarily on calculating crack growth rates and determining the design fatigue (cyclic) life in high pressure hydrogen service. Although the ASME Section VIII Division 3 high pressure vessel code requires calculation of design fatigue life for all services, the primary difference for high pressure gaseous hydrogen service is the consideration of the significant effects that high pressure gaseous hydrogen has on fatigue life. Codes and standards are important for the growing ‘hydrogen economy’ because regulators typically rely on codes and standards for assurance of the integrity of pressure vessels, piping and pipelines, so it is important that these be in place prior to construction of facilities. An example problem that describes the calculation of the design fatigue life for a steel pressure vessel in high pressure hydrogen service in accordance with the requirements of the ASME Code is provided.
