An oval opening gives an operator more usable reach through the same shell width than a round one of similar area.

Overview
Oval manhole covers are used where the tank shell is narrow or where the operator needs more usable access than a round opening of the same width provides.
They are built in stainless steel to match the vessel, with the gasket chosen for the product and the cleaning chemistry, and can be supplied with a new tank or as a replacement on an existing one.
| Cover type | Oval manhole cover |
|---|---|
| Material | Stainless steel matched to the vessel |
| Access | Oval opening for improved reach through a narrow shell |
| Gasket | Selected for product and cleaning chemistry |
| Sizing | Confirmed against the opening on both axes |
Key Benefits
The long axis gives access that a round cover of the same shell width cannot.
Oval covers are commonly arranged to pass through the opening, which suits pressure duty designs.
Material and finish matched to the vessel.
Elastomer selected for the product and the cleaning chemistry rather than supplied as standard.
Application Scenarios
Tanks where shell width limits the size of a round opening.
Vessels entered for inspection or manual cleaning.
Fitting a new cover and gasket to an existing oval opening.
An oval shape improves usable access without widening the shell opening.
A new cover and gasket sized to the existing opening restores the seal.
Correct gasket selection and seating keep the cover area as cleanable as the rest of the vessel.

Materials And Process
| Round manhole cover | Round is simpler to seal. Oval gives better access where the shell is narrow. |
|---|---|
| Rectangular manhole cover | Rectangular gives the largest opening but is the hardest shape to seal reliably. |
Use Guide
Long and short axis of the opening, plus the frame and gasket groove.
Handle, hinge and clamping arrangement are what make a replacement fit.
Atmospheric or pressure, and the cleaning chemistry and temperature.
Inspect for weeping after the first hot cleaning cycle with the new gasket.
Answers
Because it gives more usable access through a narrow shell than a round opening of the same width.
Yes. Send both axes, the frame details and a photograph of the current cover.
Stainless steel matched to the vessel.
Yes, with material chosen for the product and the cleaning cycle.
Tell us the vessel pressure with the enquiry and we will confirm what can be supplied.
