Stainless steel oval tank manhole cover

    This type of oval manhole is mainly used in beer fermentation tanks. We have  has two sizes, 480mm*580mm 340mm*440mm, which can be used in different sizes of tanks. The outer surface treatment of the oval tank manway adopts satin, and the inner surface treatment adopts mirror Polish ra<0.4um to ensure the hygienic requirements in the beer fermentation process.

    Shadowless manways are designed to be mounted flush with the exterior of the tanks, thus creating no interior protrusions, or a lip inside, where unsanitary conditions can build up; they are recommended instead of their oval counterparts. Round manways are simply designed to be an access port for pressurized brewing systems. The manway has a working pressure of 58 PSI, with a design pressure of 72.5 PSI.
