The Range
Four Cover Types For Different Tank Heads
Round covers suit flat and dished heads, oval covers fit where the operator must reach through a narrow shell, rectangular covers give the largest opening, and pressure versions are rated for vessels that work above atmospheric.

Problems It Solves
The gasket leaks after cleaning cycles
Hot cleaning solution attacks the wrong elastomer. Specify the seal against the chemistry and the temperature, not just the size.
The opening is too small to work through
Cover shape decides how well a person can reach inside. Oval and rectangular openings give more usable access on the same shell.
The cover is not rated for the vessel
A vessel that works above atmospheric needs a pressure rated cover, not a lid that happens to fit the opening.
Why This Line
What To Look At On A Cover
Shape To Suit The Head
Round, oval and rectangular versions so the opening matches the tank geometry and the access the operator needs.
Pressure Rated Versions
Pressure round manhole covers for vessels that operate above atmospheric pressure.
Built With The Tank
Covers come from the same works as the vessels, so the opening, the gasket and the finish are consistent.
Application Scenarios
Where Covers Are Fitted
On A New Vessel
Specified with the tank so the opening is cut, the ring is welded and the finish matches the shell.
As A Replacement
Fitted to an existing tank where the original cover or gasket no longer seals.
On Pressure Vessels
Pressure rated covers for vessels operating above atmospheric, supplied with the vessel documentation.

Selection Guide
Choosing A Manhole Cover
Measure The Opening
Existing opening size and shape, or the access you need on a new vessel. Send a photograph of the current cover if you are replacing one.
State The Pressure
Atmospheric or above. A pressure rated cover is a different product, not an option on a standard one.
Pick The Seal
Gasket material chosen against product contact and cleaning chemistry.
Confirm The Finish
Internal surface finish should match the vessel so cleaning behaves the same across the whole tank.
Answers
Sanitary Manhole Covers FAQ
Which shapes do you supply?
Round, oval and rectangular covers, plus pressure rated round covers for vessels working above atmospheric pressure.
Can you supply a cover for an existing tank?
Yes. Send the opening dimensions and a photograph of the current cover and ring so the replacement seats correctly.
What material are the covers made from?
Stainless steel, matched to the vessel material, normally SS304 or SS316L.
Are gaskets included?
Gaskets are supplied with the cover. Tell us the product and the cleaning chemistry so the elastomer is right.
Do you supply the spray ball as well?
Yes. Fixed spray balls and rotating spray devices are part of the sanitary fittings range and are normally specified with the manhole.

Tank Manholes And Spray Balls Specifying The Parts That Make A Vessel Work
A vessel is judged by how easily it opens, how completely it cleans and how well the seal survives. All three are decided by parts that cost a fraction of the tank.

DIN SMS 3A ISO And IDF How To Order Fittings That Actually Fit
Five standards, similar looking parts, different dimensions. Measuring one existing fitting saves more time than any catalogue.

Dimensions, pressure rating and the cleaning chemistry are enough for us to quote the cover and the gasket.
