South Korean media reported that Posco has succeeded in producing special steel pipes for hydrogen transportation by using a new steel material that greatly improved the lifespan and safety of welded connections to withstand rupture or corrosion and will supply them for the first time to the city of Ansan in Gyeonggi Province of South Korea. The new products from Posco are made to overcome the safety problem, can withstand temperatures as low as minus 45 degrees Celsius and are wider in diameterUntil now, South Korea has relied on imported, small-caliber seamless steel pipes with a width about 15 centimeters for hydrogen transportation. Bigger pipes, as wide as 20 centimeters, are needed to carry the big volume of hydrogen transfer needed in the hydrogen test bed cities such as Ansan. But imported products with welded parts were always used on a limited basis for safety issuesAnsan was designated as a hydrogen test bed by the Transport Ministry in 2019. The southern cities of Ulsan as well as Jeonju and Wanju in North Jeolla Province have also been chosen by the ministry for pilot projects to adopt hydrogen to power living facilities and public transportations there.
