Structural Connectors

Super-Tight is an advance weld less forged steel pressure vessel equipment, design to join two ends (a flanged end to a bare end) of pipes with bolting arrangement. Equipped with internal components of matching hardened steel with precise tolerances in comply with elastomeric sealing systems with accurate chemical and mechanical properties.

Benefits

  • Low torque and less number of bolting
  • Repeatable and corrective installation without dismantling the mechanism
  • Adjustable end gap to tolerate spool length
  • Test port feature to test the sealing prior to pressurizing the line
  • Tolerant of ovality with independent gripping blocks
  • Minimum pipe end preparation
  • Sour service compliant
  • Environmental seal
  • Gripping force control to avoid pipeline damage in oversized OD
  • Guiding rods (for easier and faster installation)
  • Piggable after installation
  • Cathodic protected (25+ years)
  • No hot-work permit needed
  • Diver and diver-less options
  • Mechanical /Hydraulic activation
  • Permanent installation
  • Single operation with no follow up works
  • Internal and external protective coating
  • ANSI pressure rating from 400 to 2500
  • Sizes from 4" up to 56"
  • Forged steel treated material
  • 100% hydrotested
  • N2, NBR,VITON Graphite and PU elastomer packing
  • NDT test and full inspection documentation
  • Installation saddle
  • Long-term storage packaging offered
