The Vector SPO Compact Flange has been used across the globe since 1989, offshore, onshore and subsea, offering significant weight and space savings over conventional flanges, leak-free joint integrity and therefore is the most effective environmentally friendly piping joint available today.Its double sealing action prevents hydrocarbon releases, addressing health and safety issues and concerns.
Typically weighing between 70 - 82% less than a conventional flange, the Vector SPO Compact Flange is designed using state-of-the-art finite element analysis and is in full accordance with ASME VIII, Div 2 provisions and with ANSI/ASME B31.3.
The Vector SPO Compact flange is up to 60% smaller and 80% lighter proven alternative to conventional ASME flanges.
No relative flange movement of SPO components even under extreme loads.The only flange that meets the strict design requirements in DNV-OS-F201 and ISO 13628-7.
The faces have full contact at the internal bore. There is no discontinuity which can disturb the flow.
Suitable for high pressure (available up to 20,000psi) or extreme temperature requirements
No corrosion/erosion problems on SPO® Compact Flange faces.
High integrity product, providing a 100% leak free connection protecting the environment. Often used in critical areas where conventional flanges are not accepted.
Compact bolt tensioners & standard torque tools are available for easy make-up. Compact Flanges require less time to makeup than conventional flanges.

Freudenberg Oil & Gas Technologies’ Vector SPO® Compact Flange dual-seal hydrocarbon release prevention has been tested up to 20k psi, which makes the Vector SPO® Compact Flange the most environmentally friendly piping joint available today.
Highly reliable with a probability of leakage in the same range as a pipe-girth weld, the Vector SPO® Compact Flange has been subjected to an intensive, full-scale verification and testing programme. Finite element analysis and full scale testing was used in pre-qualification for riser installations. There was close correlation between FEA and full scale test results.
The flange’s static behavior under any design load condition ensures that neither dynamic, nor static loading, will degrade the seal performance or other characteristics within the capacity of the corresponding pipe. Furthermore, the bolted joint fatigue life exceeds the fatigue life of the adjoining welded pipe. This high performance is achieved through its unique design and full flange face contact. Due to the high preloading of the bolts, no adjustment or re-tightening is required in service. Indeed, the Vector SPO® Compact Flange has been successfully deployed in temperatures ranging from -200 °C to +720 °C with absolutely no need for bolt re-tightening.
FIGURE STATIC CONNECTION: Dynamic loading does not have an impact on the Vector SPO® Compact Flange, however, on the ASME flange the bolting may loosen and the flange will start leaking (when bolting hasn’t been re-tightened within due time).
