Piperack units expansion on Hellenic Petroleum Industry
Piperack units expansion and strengthening on Hellenic Petroleum Industry

The projects involve the control of structural adequacy, the expansion and strengthening of four piperacks on Hellenic Petroleum Industry in Thessaloniki, having a total length of 400 metres. These piperacks were constructed from the beginning of the factory operation in 1965. For each one an analytical finite element model was developed using the software
Strand7. The analysis was done with non-linear stress-strain law and geometrical non-linearity.
