EPDM / Silicon / NBR / FKM

Sanitary Stainless Steel Oval Inward Manhole

  • Non-pressurized tank manholes are available in SS304 or SS316 (as special order).
  • Their primary application is to make the liquid in the tank accessible, allow checking of liquid levels.
  • While still retaining control over the head-space atmosphere of the tank - manholes do seal and prevent air exchange.
  • But are not designed to withstand the stronger pressure like tank manways.
  • Manholes are usually mounted on top of the tank with the size depending on the condition application: larger for ease of adding solids, or smaller for adding liquids or powders.
