•  SPO compact flange was developed by Steelproducts Offshore A/S, using 
   extensive testing and finite element analysis. 
---------------------------------------------------------------------------------------------------------------------
•  First used for a workover riser in 1989 and subsequently for production and
   export risers. No operational leakage for more than 400.000 flange-years of
   operation, mainly thanks to the 100% static sealing conditions.
---------------------------------------------------------------------------------------------------------------------
•  Engineered with additional capacity to accommodate external loads, valve
   neck configurations and standard make-up tools
---------------------------------------------------------------------------------------------------------------------
•  Independently verified as a high quality, highly reliable connector with the 
   mechanical strength of a girth weld
---------------------------------------------------------------------------------------------------------------------
•  The SPO compact flange has two independent seals in series together with
   an additional environmental seal.
---------------------------------------------------------------------------------------------------------------------
•  Designed to be used in temperatures ranging from -200ºC to 720ºC
---------------------------------------------------------------------------------------------------------------------
•  One sealring size for each nominal pipe size 
---------------------------------------------------------------------------------------------------------------------
•  Designed as a static connection, removing the disadvantages of the dynamics
   provided by conventional flanges like gasket relaxation, cyclic flange rotation,
   flange separation, bolt bending, non-uniform bolt load,...
---------------------------------------------------------------------------------------------------------------------
•  SPO compact flange can be used as well for subsea applications
