•  SPO compact flange was developed by Steelproducts Offshore A/S, using 
   extensive testing and finite element analysis. 
---------------------------------------------------------------------------------------------------------------------
•  First used for a relief well riser in 1989 and subsequently for production and
   export risers. Today over 60,000 in service
---------------------------------------------------------------------------------------------------------------------
•  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 bore
---------------------------------------------------------------------------------------------------------------------
•  Designed as a static connection, removing the disadvantages of the dynamics
   provided by conventional flanges
---------------------------------------------------------------------------------------------------------------------
•  SPO compact flange can be used as well for subsea applications
