General

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.

VERAX has gone into detail in a number of issues in order to find the truth behind the boilted joint. The results are available for download below:

• Risk analysis - conventional, ANSI- versus modern, VCF-joint
• The theory behind the non-gaskeded pipe joint - Experimental verification
• The VERAX Compact Flange System - Structural Integrity
• An analysis of the effect of contact surface damage
