ASME B31.8 covers transmission and local distribution of natural gas. This chapter discusses the 2020 Edition of B31.8. ASME B31.8S is a supplement to B31.8 covering integrity management of natural gas transmission pipelines. This chapter discusses the 2020 Edition of B31.8S. B31G covers evaluation of the fitness for service of B31.4 and B31.8 pipelines affected by corrosion. This chapter discusses the 2020 Edition of B31G. B31Q covers the qualification of frontline personnel who work on B31.4 and B31.8 pipeline systems. This chapter discusses the 2021 Edition of B31Q.
