Description

Our ASME code elliptical manway assemblies are designed in accordance with ASME Sec VIII-1 standards.  They are meant for use in ASME code pressure vessels and allow access to the interior of the vessel.  The self-sealing design allows for the internal pressure of the tank to force the cover tightly against the ring which is separated by a neoprene gasket.  Pressure ratings are determined by the cover.
