How can you be sure of the precise pump setting?
By careful design of the Boreline reinforcement, the extension of the riser has been minimised to balance the extension effect of axial loads against the reverse effect of internal pressure. The precise extension of the Boreline riser can be predicted with reasonable accuracy and, as a rule, will not exceed 2%. The riser can swell radially up to 15% at the maximum operating pressures which benefits hydraulic efficiency.
