Road Fuel Tanker Top Manhole Cover in European Standard

Safety Features

1) With an impressive emergency venting capacity of 7000m³/hr, the pressure-actuated fill cap stands as a robust guardian against tank explosion, providing essential protection in the event of a fire.

2) Ingeniously designed, all bolt holes are blind, preventing them from penetrating to the underside of the manhole cover. This critical feature ensures that no liquid cargo can seep through, maintaining utmost integrity and safety.

3) Strategically cast webs on the underside of both the base plate and the fill cap significantly enhance the structural integrity, offering fortified support.

4) Equipped with four visible, corrosion-proof, plated springs, this emergency venting mechanism is designed for reliability and longevity.A noteworthy advantage is that the springs are not encased in a rubber sleeve, a design flaw in other manufacturers' covers that has led to significant failures.
