Original condition

The manhole joint was causing long-term problems due to the use of a small number of bolts and thus developing insufficient specific pressure on the seal.

New solution

  • Complete coupling analysis
  • Calculation and design of sealing with respect to the new fastener material (treated with DEPAC metal-free paste)
  • POWERgraf HP Premium gasket dimension adjusted to achieve higher leak class in all operating conditions
  • Damage to flanges caused by pitting corrosion was found during implementation - levelled with POWERgraf Cor tape
  • Controlled tightening of manhole holes to the calculated tightening torque
  • Successful pressure test

Result - guarantee of tightness
