The MAXFLOW MIDLINE (MFML) is a straight, full-bore, pressure-balanced Hot Stab.
The MAXFLOW Hot Stab is the world’s first straight-through, pressure-balanced stab connector. It incorporates Secc’s patented MAXFLOW zero head-loss technology and is ideally suited to high-flow operations where a conventional API 17H hot stab of the same bore size is limited by relatively large pressure drops.
The balanced geometry provides the lowest pressure drop possible across any Hot Stab equivalent and zero axial hydrostatic force on the retention system.
The straight-through, full bore permits maximum flow at minimum pressure. A 1″ MAXFLOW performs the same as a 2″ conventional hot stab and a 2″ MAXFLOW the same as a 4″conventional hot stab.
Utilising the MAXFLOW, engineers are able to consider reducing the bore size or pressure rating of the subsea infrastructure. Additionally pumps, valves and other pressure related equipment can be appropriately sized. All of this can lead to significant cost and weight savings on subsea projects.
Secc’s pressure balanced geometry has been utilised for over 20 years.
