CLAMP CONNECTOR

VIAR-LOCK® (4 BOLDS CLAMP CONNECTOR)
VIAR LOCK is a type of connection composed by two hubs, a seal ring and two clamps tightened by bolts and nuts.VIAR LOCK can be used in most of application of welding neck, with the following advantages:

  • Lower installation cost in 600 class and higher services
  • Minimized maintenance
  • Reduced cost during performance
  • High joint performance under the effect of external forces
  • High joint performance under the effect of thermal loads: the bolts are not directly involved by the process fluid and this minimizes the “bolt relaxation effect”
  • Lower torque requirements with no necessity of special tensioning tools
  • Self-energized and pressure energized seal ring
  • Reusable seal ring
  • Compact assembly
  • Quick assembly: 4 bolts on the clamp
  • No overstress of the connector during over-tightening of the bolt
  • No bolt holes to align
  • Few parts
  • Lighter structure
