Fan-Shaped Tank Manway with Single Handwheel

A sector-shaped tank opening

The fan-shaped cover and collar provide a different opening outline from round, oval or rectangular manways. The design is described for small-diameter mixing tanks, where the space available on the tank head is an important layout consideration. Compare the actual outline with the intended access opening.

Handle, hinge and side closure

The product photograph shows a top bar handle, hinge attachment at the narrow end and a single handwheel fastening position on the opposite side. These visible features help identify the closure arrangement. Plan access to the handwheel and space for the cover rather than relying only on the outline of the opening.

Welded collar and material choices

The listed connection is welding and the metal options are SS304 or SS316L. The series also lists silicone, EPDM, Viton and NBR seal choices. Select a seal that matches the actual sector profile and process conditions; a material name alone does not identify a matching perimeter gasket.

Layout information for ordering

Specify the required opening outline, collar geometry and surrounding clearance with the tank layout. The arc, chord and sector angle need to be confirmed for the ordered assembly before preparing the tank opening. Routine checks can focus on the visible handle, hinge, closure and seal seating surfaces.
