The space available to connect in the additional tank drainage pipework was very limited. Great care and consideration were required to design a tie-in branch to the existing pipework. Room for installing bolts was critical to ensure constructability. A narrow window of time to install the tie-in demanded an accurate design to avoid site works.
The pipework was designed in 3D. This enabled critical elements to be accommodated including generating enough space to install the fixing bolts and having adequate space to enable welding of the fittings.
The initial tie-in branch spool was successfully fitted during the first short availability window. With the new tank installed the connecting pipework was quickly added and the new tank made available for service. No problems were encountered on site during any of the installation work.
Space constrained tie-in pipework connection.
At a STW an additional tertiary filter tank was to be installed. The outlet required connecting into the above ground drainage pipework for the neighbouring tank.
Calculating the thrust forces acing on an elbow.
When an open ended horizontal pipe was to have an elbow fitted to direct the flow vertical, we were asked to calculate the forces and verify the structural support elements.
