MANAWAYDOORS, MANHOLES, LIDS AND DOORS
Depending on the application we differentiate between:
Manhole: Manhole access to the tank through which a man can pass
Doors: Vertical access to the tank. They have to withstand the pressure of the liquid column
Lids and Gauge Hatches: non-large tank access for a measurement or inspection of the tank. They are installed on the roof of the tanks and only have to withstand the internal pressure of the tank, being able to be for applications with atmospheric or pressure pressures.
Quick Opening closures: Doors for pressure pipes, filters, reactors, designed to withstand large pressures of up to 300 bar, facilitating access and ensuring a tight seal.
