As a result of extensive research into the nature and behaviour of the bolted joint it is now technically  feasable to build such, which are stronger than the members joined.

  • A VCF-joint can be made as strong as the associated pipe itself.

  • Nowhere in a VCF-flange are there tensile stresses as high as in the pipe.

  • In the bolts there are no concentrated stresses from bending.

  • Bolts are being preloaded to above 80% of their minimum guaranteed yield strength.

  • Education, training and detailed instructions may be provided for mechanics to become qualified to bolt up VCF-joints.

 A detailed comparison between VCF and a convensional joint is available for download in swedish and  english.
