Updated KGS Standards for Hydrogen and LPG Piping in South Korea
12. September 2024The Gas Technology Standards Committee (Chairman Shin Dong-il) recently convened its 155th meeting, where 15 revisions to detailed standards, including KGS FU671, were reviewed and approved. These updates involve significant changes to the standards governing hydrogen pipelines, particularly regarding the electrical method, non-destructive inspection procedures, and seismic design for buried pipelines. Additionally, new standards for ventilation in hydrogen fuel cell rooms and the painting of hydrogen piping have been introduced to better align with practical, on-site conditions. Pressure piping materials typically require KGS certification to be approved for import and sale in South Korea.
The meeting also focused on revisions related to city gas and liquefied petroleum gas (LPG) facilities. For city gas systems, updated standards for pipes installed in homes and for sound-absorbing materials in pressure regulator rooms have been clarified. Meanwhile, the LPG division introduced new standards for installing fixed image information processing devices at charging stations to enhance safety. These changes, along with adjustments to standards for river crossing installations and airtightness tests for buried pipes, are expected to be approved by the Ministry of Trade, Industry and Energy soon, with the revised standards becoming official upon publication.
