Round Manway with Central Handwheel

A central handwheel and crossbar

One handwheel sits at the centre of the solid round cover, with a crossbar spanning the opening. This visible arrangement distinguishes the manway from designs using handwheels around the perimeter. The cover and collar should be identified together when comparing replacement assemblies or preparing a tank-access layout.

Non-pressure design and welded interface

The product is listed as a non-pressure round manway and has a welding connection to the tank. Use that design classification when selecting the intended access point. The actual collar dimensions and surrounding clearances need to be defined for the chosen assembly rather than taken from the product photograph.

Material and reference-series choices

SS304 and SS316L are listed material options. The page also gives a 200–600 mm reference-series size range and silicone, EPDM, Viton and NBR seal options. These choices provide a starting point for selection; the seal profile, collar geometry and cover configuration must correspond to the same ordered assembly.

Access around the centre closure

Reserve space to reach the handwheel and to move the cover and crossbar during routine access. Nearby fittings should be considered when planning that space. Maintenance checks can focus on the visible closure parts and seal seating area, with worn or damaged parts replaced by components matching the actual assembly.
