Customer cases

higher strength steel in district heating pipeline core tubes

Helen decreased carbon footprint in Vuosaari power plant by using SSAB’s higher strength steel tubes

LOGSTOR Finland delivered to Helen Vuosaari power plant district heating pipe line that were produced with thinner steel core pipelines made of higher strength steel. This was the first large size project for Helen to use higher strength steel in district heating pipeline. Higher steel grade enables customer to use lower material thickness tubes in steel core of pipelines which not only reduce weight of the pipes during the transportation but also prolongs lifetime of the pipelines. Power plant is benefiting of the longer lifetime compared with traditional solution and at the same time environment aspect with lower carbon footprint are enabled.
