Oval manway A309

The A309 oval manway is built into the side wall of a stainless steel pressure tank and opens to the inside. During production, the manway is bent to the specific diameter of the tank, which is why it is manufactured only on request. This model is suitable for tanks with a diameter of Ø900 mm and larger.

 

Manway A309 is made from AISI 304/304L stainless steel as standard, and optionally from AISI 316L grade steel. A wide range of elastomers used for gaskets, allows the manway to be applied for a broad spectrum of working media (fluids, liquids).

The use of stainless steel oval manway A309

The main areas of application are:

  • brewery tanks,
  • fermentation industry,
  • beverage, wine and spirits production,
  • chemical and biotechnology industries.

The A308/A308R elliptical manways are also used successfully in other applications, provided that the operating environment is suitable in terms of the properties of the materials used in their construction.
